3 GNRAL TK-760G/(N)/762G/(N) 2. PR-INSTALLATION CHCKOUT 2-. Introduction ach radio is adjusted and tested before shipment. However, it is recommended that receiver and transmitter operation be checked for proper operation before installation Testing The radio should be tested complete with all cabling and accessories as they will be connected in the final installation. Transmitter frequency, deviation, and power output should be checked, as should receiver sensitivity, squelch operation, and audio output. Signalling equipment operation should be verified.. PLANNING TH INSTALLATION -. General Inspect the vehicle and determine how and where the radio antenna and accessories will be mounted. Plan cable runs for protection against pinching or crushing wiring, and radio installation to prevent overheating. -2. Antenna The favored location for an antenna is in the center of a large, flat conductive area, usually at the roof center. The trunk lid is preferred, bond the trunk lid and vehicle chassis using ground straps to ensure the lid is at chassis ground. -. Radio The universal mount bracket allows the radio to be mounted in a variety of ways. Be sure the mounting surface is adequate to support the radio s weight. Allow sufficient space around the radio for air cooling. Position the radio close enough to the vehicle operator to permit easy access to the controls when driving. -4. DC Power and wiring. This radio may be installed in negative ground electrical systems only. Reverse polarity will cause the cable fuse to blow. Check the vehicle ground polarity before installation to prevent wasted time and effort. 2. Connect the positive power lead directly to the vehicle battery positive terminal. Connecting the Positive lead to any other positive voltage source in the vehicle is not recommended.. Connect the ground lead directly to the battery negative terminal. 4. The cable provided with the radio is sufficient to handle the maximum radio current demand. If the cable must be extended, be sure the additional wire is sufficient for the current to be carried and length of the added lead. 4. INSTALLATION PLANNING CONTROL STATIONS 4-. Antenna system Control station. The antenna system selection depends on many factors and is beyond the scope of this manual. Your KNWOOD dealer can help you select an antenna system that will best serve your particular needs Radio location Select a convenient location for your control station radio which is as close as practical to the antenna cable entry point. Secondly, use your system s power supply (which supplies the voltage and current required for your system). Make sure sufficient air can flow around the radio and power supply to allow adequate cooling. SRVIC This radio is designed for easy servicing. Refer to the schematic diagrams, printed circuit board views, and alignment procedures contained in this manual. Note When you modify your radio as described in system setup, take the following precaution. The rating of pin 7 (SB) of the accessory connector cable (KCT-9) on the rear of the radio is.2v (A). Insert a A fuse if you use the SB pin for external equipment Accessory connector cable (KCT-9) If you do not intend to use the.5-mm jack for the external speaker, fit the supplied speaker-jack cap (B ) to stop dust and sand getting in.

Scan Operating (TK-760G only) Scan types Single group scan You can scan all valid (ADD) channels in the displayed group that can be selected with the group up/down key. Multiple group scan You can scan all valid (ADD) channels in the all valid (ADD) group. SCAN start condition One or more non-priority channels must be added to all channels that can be scanned. The transceiver must be in normal receive mode (PTT off). When you activate the key programmed to the scan function, the scan starts. The scan icon SCN lights and SCAN is indicated on alphanumeric display. Scan stop condition The scan stops temporarily if the following conditions are satisfied. ) A carrier is detected, then signalling matches on channels for which receive the signalling is set by the programming software. 2) A carrier is detected on the channels for which receiving signalling is not set by the programming software or when the monitor (signalling cancel) function is activated. 8

9 OPRATING FATURS TK-760G/(N)/762G/(N) Scan channel types ) Priority channel is the most important channel for the scan, and always detects a signal during scan and when the scan stops temporarily. 2) Non-priority channels detects a signal during scan. For the channels that can be selected with the group or channel up/down key when the scan does not occur, adds an indicator A lights. Priority channel setting A priority channel can be set as follows with the programming software (KPG-67D). ) Specify a priority channel as a fixed priority channel. 2) Make a selected channel, a priority channel. Scan type according to the priority channel ) When no priority channel is set : Only the non-priority channels are scanned. If a non-priority channel stops temporarily, it stops until there is no signal on the channel. 2) When priority channel is set : ither priority channel is scanned. If a non-priority channel stops temporarily, a priority channel signal is detected at certain intervals. If a priority channel stops temporarily, it stops until there is no signal on the priority channel. Revert channel The revert channel is used to transmit during scanning and set by the programming software (KPG-67D). ) Priority The transceiver reverts to the priority channel. 2) Priority with talkback The transceiver reverts to the priority channel. If you press PTT during a resume timer (dropout delay time, TX dwell time) or calling, you can transmit on current channel to answer to the call however revert channel is set to priority channel. After resume time, scan re-starts and transmission channel is return to priority channel. ) Selected channel The transceiver reverts to the channel before scanning or the channel that you changed during scan. 4) Last called channel The transceiver reverts to the last called channel during the scan. 5) Last used channel The transceiver reverts to the last used (transmitted) channel during scan. Last used revert channel includes talkback function. 6) Selected with talkback The transceiver reverts to the channel before scanning or the channel that you changed during scan. Scan end When you reactivate the key programmed to the scan function during scan mode, the scan ends. The scan icon SCN and SCAN display goes off. Temporarily delete/add It is possible to delete or add channel temporarily during scan. When scan stops on unnecessary channel for example by interference of the other party, activate the delete/ add function (for example press the key), then that channel is deleted temporarily and scan re-start immediately. When you would like to add the deleted channel temporarily to scan sequence, select the desired (deleted) channel during scan, activate the delete/add function (for example press the key) before scan re-start. That channel is added temporarily to scan sequence. The temporary deleted or added channels are returns to pre-set delete/add, when the transceiver exits from scan mode. 5. Details of Features Time-out timer The time-out timer can be programmed in 5 seconds increments from 5 seconds to ten minutes. If the transmitter is keyed continuously for longer than the programmed time, the transmitter is disabled and a warning tone sounds while the PTT button is held down. The alert tone stops when the PTT button is released. PTT ID PTT ID provides a DTMF ANI to be sent with every time PTT (beginning of transmission, end of transmission, or both). You can program PTT ID on or off for each group. The contents of ID are programmed for each channel. The timing that the transceiver sends ID is programmable. BOT : DTMF ID (BOT) is sent on beginning of transmission. OT : DTMF ID (OT) is sent on end of transmission. Both : DTMF ID (BOT) is sent on beginning of transmission and DTMF ID (OT) is sent on end of transmission. Radio password (TK-760G only) When the password is set in the transceiver, user can not use the transceiver unless enter the correct password. This code can be up to 6 digits from 0 to 9 and input with the key, and SCN key. Off hook decode If the Off hook decode function has been enabled, removing and replacing the microphone on the hook has no effect for decoding QT/DQT and option signalling. TOT pre-alert The transceiver has TOT pre-alert timer. This parameter selects the time at which the transceiver generates TOT pre-alert tone before TOT is expired. TOT will be expired when the selected time passes from a TOT pre-alert tone. 9

10 TK-760/G(N)/762G/(N) OPRATING FATURS TOT re-key time The transceiver has TOT re-key timer. This timer is the time you can not transmit after TOT exceeded. After TOT re-key time expired you can transmit again. TOT reset time The transceiver has TOT reset timer. This timer is the minimum wait time allowed during a transmission that will reset the TOT count. TOT reset time causes the TOT to continue even after PTT is released unless the TOT reset timer has expired. Clear to transpond The transceiver waits the transpond of 5-tone/2-tone / DTMF if channel is busy until channel open. This feature prevents the interference to other party. 6. Option Signalling (DTMF/2-Tone) Built-in DTMF decoder is available for option signalling. Built-in 2-tone decoder is available for option signalling. It is possible to use individual call, group call, D.B.D. (Dead Beat Disable). D.B.D. is used with DTMF only. If the option signalling matches, a predetermined action will occur. If option signalling matches on a group/channel which is set up with option signalling, the option signalling indicator (CALL) will flash and option signalling will be released. The transpond or alert tone will sound. The orange LD will flash. While option signalling matches (or if option signalling is deactivated when you are transmitting), you can mute or unmute QT/DQT/Carrier. AND/OR You can select AND or OR for option signalling match conditions. AND OR AND OR Alert/Transpond QT/DQTDTMF (2-tone); Option matches = Action QT/DQTDTMF (2-tone); Option matches = Action AF mute open QT/DQTDTMF (2-tone); Option matches = Action QT/DQT/ID; Signalling only matches = Action With OR set up, alert/transpond will not function with only DTMF. With OR set up, AF mute will not release when only DTMF matches. With a conventional channel not set up with QT or DQT, only the carrier is considered when signalling matches. Auto Reset If option signalling matches a group set up with option signalling, option signalling is released. After matching option signalling, option signalling will temporarily reset automatically. Dead Beat Disable If the D.B.D. code matches, a predetermined action will occur. Whether option signalling is activated or not, when D.B.D. matches on any channel, the transceiver will become TX inhibited or TX/RX inhibited. While D.B.D. is active, if the D.B.D. code # code is received, D.B.D. will disactivate. When D.B.D. matches, transpond will function. Alert will not be output, and option signalling match icon will not appear. 7. Audible User Feedback Tones The transceiver outputs various combinations of tones to notify the user of the transceiver operating state. The main tones are listed below. The high tone is 477Hz, the mid tone is 94Hz, and the low tone is 770Hz. Power on tone This tone is output when the transceiver is turned on. (The high tone is output for 500ms.) Alert tone This tone is output when the transceiver is TX inhibition for TOT, and PLL unlocked. It is output until the PTT button is released. DBD on tone When a D.B.D. code is received, transpond tone sounds. DBD off tone When a D.B.D. release code is received, transpond tone sounds. Busy tone Sounds in conventional mode, when busy channel lockout is functioning. You can select yes or no for the optional feature s warning tone. Group call tone Sounds when a group call with the correct DTMF/2-tone option signalling is received, repeats 7 times. You can select yes or no for the optional feature s warning tone.

Preface The TK-760G/762G transceiver is programmed using a personal computer, a programming interface (KPG-46) and programming software (KPG-67D). The programming software can be used with an IBM PC or compatible. Figure shows the setup of an IBM PC for programming Connection Procedure. Connect the TK-760G/762G to the personal computer with the interface cable. 2. When the Power is switched on, user mode can be entered immediately. When the PC sends a command, the radio enters PC mode. When data is transmitted from transceiver, the red LD blink. When data is received by the transceiver, the green LD blink. Notes : The data stored in the personal computer must match model type when it is written into the flash memory. Change the TK-760G/762G to PC mode, then attach the interface cable. 5-. KPG-46 Description (PC programming interface cable : Option) The KPG-46 is required to interface the TK-760G/762G with the computer. It has a circuit in its D-subconnector (25- pin) case that converts the RS-22C logic level to the TTL level. The KPG-46 connects the modular microphone jack of the TK-760G/762G to the computers RS-22C serial port. IBM-PC KPG Programming Software KPG-67D Description The KPG-67D is programming software for the transceiver supplied on two.5" floppy disks. This software runs under MS-DOS. or later on an IBM-PC or compatible machine. The data can be input to or read from the transceiver and edited on the screen. The programmed or edited data can be printed out. It is also possible to tune the transceiver. We recommend that install the KPG-67D for example to harddisk first then use it. 6. Firmware Programming Mode 6-. Preface Flash memory is mounted on the TK-760G/762G. This allows the TK-760G/762G to be upgraded when new features are released in the future. (For details on how to obtain the firmware, contact Customer Service.) 6-2. Connection Procedure Connect the TK-760G/762G to the personal computer (IBM PC or compatible) with the interface cable (KPG-46). (Connection is the same as in the PC Mode.) 6-. Programming.

24 CIRCUIT DSCRIPTION Frequency Configuration The receiver utilizes double conversion. The first IF is 49.95MHz and the second IF is 450kHz. The first local oscillator signal is supplied from the PLL circuit. The PLL circuit in the transmitter generates the necessary frequencies. Figure shows the frequencies.

The frequency configuration is shown in Figure. Front-end RF Amplifier An incoming signal from the antenna is applied to an RF amplifier (Q27) after passing through a transmit/receive switch circuit (D and D4 are off) and a band pass filter (L8). After the signal is amplified (Q27), the signal is filtered through a band pass filter (L, L and L5) to eliminate unwanted signals before it is passed to the first mixer. Band pass filters (L8, L, L and L5) have varactor diodes (D0, D, D8, D2 and D28). The voltage of these diodes are controlled by to track the CPU (IC502) center frequency of the band pass filter. (See Fig. 2) First Mixer The signal from the RF amplifier is heterodyned with the first local oscillator signal from the PLL frequency synthesizer circuit at the first mixer (Q5) to create a 49.95MHz first intermediate frequency (st IF) signal. The first IF signal is then fed through one pair of monolithic crystal filters (MCF : XF) to further remove spurious signals. SP MIC IF Amplifier The first IF signal is amplified by Q, and the enters IC5 (FM processing IC). The signal is heterodyned again with a second local oscillator signal within IC5 to create a 450kHz second IF signal. The second IF signal is then fed through a 450kHz ceramic filter (CF2) to further eliminate unwanted signals before it is amplified and FM detected in IC5.

25 CIRCUIT DSCRIPTION TK-760G/(N)/762G/(N) AF Signal System The detection signal (DO) from the TX-RX unit goes to the audio processor (IC508) of the control unit. The signal passes through a filter in the audio processor to adjust the gain, and is output to IC507. IC507 sums the AF signal and the DTMF signal, BP signal and returns the resulting signal to the TX-RX unit. The signal (AFO) sent to the TX-RX unit is input to the D/A converter (IC6). The AFO output level is adjusted by the D/A converter. The signal output from the D/A converter is input to the audio power amplifier (IC). The AF signal from IC switches between the internal speaker and speaker jack (J) output. DO CONTORL UNIT IC508 IC507 IC6 AFO AUDIO PROC. FIg. SUM AMP DTMF D/A CONV. AF signal system IC AF PA Squelch Circuit The detection output from the FM IF IC (IC5) passes through a band-pass filter and a noise amplifier (Q0) in the control unit to detect noise. A voltage is applied to the CPU (IC502). The CPU controls squelch according to the voltage (ASQ) level. The signal from the RSSI pin of IC5 is monitored. The electric field strength of the receive signal can be known before the ASQ voltage is input to the CPU, and the scan stop speed is improved. SP PLL Frequency Synthesizer The PLL circuit generates the first local oscillator signal for reception and the RF signal for transmission. PLL The frequency step of the PLL circuit is 5 or 6.25kHz. A 6.8MHz reference oscillator signal is divided at IC by a fixed counter to produce the 5 or 6.25kHz reference frequency. The voltage controlled oscillator (VCO) output signal is buffer amplified by Q06 (Sub-unit), then divided in IC by a dual-module programmable counter. The divided signal is compared in phase with the 5 or 6.25kHz reference signal in the phase comparator in IC. The output signal from the phase comparator is filtered through a low-pass filter and passed to the VCO to control the oscillator frequency. (See Fig. 5) VCO The TK-760G/762G has VCO in a Sub-unit (A) housed in a solid shielded case and connected to the TX-RX unit through CN0. The operating frequency is generated by Q0 in transmit mode and Q0 in receive mode. The oscillator frequency is controlled by applying the VCO control voltage, obtained from the phase comparator, to the varactor diodes (D02 and D04 in transmit mode and D0 and D0 in receive mode). The RX (ST) pin is set low in receive mode causing Q02 to turn Q0 off, and turn Q0 on. The RX (ST) pin is set low in transmit mode. The outputs from Q0 and Q0 are amplified by Q06 and sent to the buffer amplifiers.

During transmission, the 8RC signal goes low, the 8TC signal goes high and Q29 turns on. Q28 turns on and a voltage is applied to 8T. The CPU in the control unit monitors the PLL (IC) LD signal directly. When the PLL is unlocked during transmission, the PLL LD signal goes low. The CPU detects this signal and makes the 8TC signal low. When the 8TC signal goes low, no voltage is applied to 8T, and no signal is transmitted.

Unlock circuit Q28 SW Q29 SW 8TC 8T Transmitter System Outline The transmitter circuit produces and amplifies the desired frequency directly. It FM-modulates the carrier signal by means of a varicap diode Power Amplifier Circuit The transmit output signal from the VCO is amplified to a specified level of the power module (IC400) by the drive block (Q22 and Q25). The amplified signal passes through the transmission/reception selection diode (D6) and goes to a low-pass filter. The low-pass filter removes unwanted high-frequency harmonic components, and the resulting signal is goes the antenna terminal. APC Circuit The automatic transmission power control (APC) circuit detects part of a power module output with a diode (D5, D6) and applies a voltage to IC5. IC5 compares the APC control voltage (PC) generated by the D/A converter (IC6) and DC amplifier (IC7) with the detection output voltage to control Q and Q2, generates DB voltage from B voltage, and stabilizes transmission output. The APC circuit is configured to protect over current of the power module due to fluctuations of the load at the antenna end and to stabilize transmission output at voltage and temperature variations.

The KOUT0 to KOUT2 ports are always high, while the KIN0 to KIN2 ports are always low. The microprocessor monitors the status of the KIN0 to KOUT2 ports. If the state of one of the ports changes, the microprocessor assumes that the key at the matrix point corresponding to that port has been pressed. IC502 CPU KIN0 KIN KIN2 KOUT0 KOUT KOUT2 VOL DN D/A CH DN GRP DN CH UP VOL UP A GRP UP Memory Circuit The transceiver has a 2M-bit (256k x 8) flash ROM (IC50) and an 8k-bit PROM (IC505). The flash ROM contains firmware programs, data and user data which is programmed with the FPU. The PROM contains adjustment data. The CPU (IC502) controls the flash ROM through an external address bus and an external data bus. The CPU controls the PROM through two serial data lines. IC50 FLASH ROM ADDRSS BUS DATA BUS Fig. 0 IC502 CPU SCL SDA Memory circuit IC505 PROM Display Circuit The CPU (IC502) controls the shift register (IC50) and display LDs. When the LD line goes high when the transceiver is busy, Q508 turns on and the green LD on D52 lights. In transmit mode, the LD0 line goes high, Q504 turns on and the red light lights. Backlighting LDs for the key operation unit (D509~D54) and LCD are provided. When the MBL line goes high, Q506 turns on, then Q505 turns on, and the key illumination LD lights. A voltage is applied to the MBL line to turn on the LCD backlight. Fig. 2 Key matrix circuit ncode The QT and DQT signals are output from TO of the CPU (IC502) and summed with the external pin DI line by the summing amplifier (IC2) and the resulting signal goes to the D/A converter (IC6) of the TX-RX unit. The DTMF and 2- TON signals are output from DTMF of the CPU and goes to the audio processor (IC508). The signal is summed with a MIC signal by the audio processor (IC508), and the resulting signal passes through an analog switch (IC509) and goes to the TX-RX unit (MO). The D/A converter (IC6) adjusts the MO level and the balance between the MO and TO levels. Part of a TO signal is summed with MO and the resulting signal goes to the MD pin of the VCO. This signal is applied to a varicap diode in the VCO for direct FM modulation.

28 CIRCUIT DSCRIPTION Decode QT/DQT/DTMF The signal (DO) detected by the TX-RX unit passes through two low-pass filters of IC5, goes to TOI of the CPU (IC502) to decode QT, DQT. The DTMF signal is decoded by a dedicated IC (IC5) and the resulting signal is sent to the CPU (IC502) as serial data. 2-tone, 5-tone The detected signal passes through audio processor (IC508) RX OUT. Then it is filtered through IC54 2-stage low-pass filtered to enter CPU (IC502) to decode 2-tone and 5-tone signalling. IC502 CPU IC5(2/2) LPF TOI STD 2TN IC5 DTMF DCO. IC54(2/2) LPF Fig. 4 IC5(/2) LPF IC54(/2) LPF RXOUT Decode DO IC508 Audio processor D/A Converter The D/A converter (IC6) is used to adjust TON and MO modulation, AF volume, TV voltage, FC reference voltage, and PC POWR CONTROL voltage level. Adjustment values are sent from the CPU as serial data. The D/A converter has a resolution of 256 and the following relationship is valid: D/A output = (Vin VDAref) / 256 x n VDAref Vin: Analog input VDAref: D/A reference voltage n: Serial data value from the microprocessor (CPU) Horn Control The horn switch, consisting of Q, Q5, and Q6, controls the horn relay. It is supplied by the dealer to provide the external horn alert function. Q6 disables horn alert, turning on when its base is high, to inhibit the function. Normally, the output from IC9 is low, and Q5 is off; the base of Q is about 0V and Q is off. When horn alert is enabled, the output from IC9 goes high and Q5 turns on. The base current flows through R2 to Q to turn Q on. Q can sink a maximum of 00mA. If the optional KAP- is used, it can drive up to 2A. PA Switch If the optional KAP- is used (see the separate section for details), the PA (Public Address) function becomes available. In this case, the signal flow changes as follows; PA off For TX, the switch which is between pins 0 and of IC509 closes. The audio signal from the microphone passes through IC509 and IC6 and modulates the VCO. For RX, the switch which is between pins and 4 of IC509 closes. The detected signal passes through IC509, IC508, IC507, IC6 and IC and is then output to the speaker. PA on Since the switch which is between pins 0 and of IC509 is open, the switch which is between pins and 4 of IC509 is open, and the switch which is between pins and 2 of IC509 is closed, the audio signal from the microphone passes through IC508, IC507 and IC6, and then goes to IC. The signal is output to the external PA system through the PA relay in KAP-. MIC IC507 IC508 IC509 OP AMP MB Audio processor IC6 D/A converter Fig. 6 DO VCO IC Power AMP Power Supply Circuit When the POWR switch on the control unit is pressed, the PSW signal goes low. This signal is inverted by Q26 and sent to a flip-flop IC (IC4). This IC outputs a control signal when the PSW goes low. When the power turns on, pin of IC4 outputs a low signal and Q20 turns on. The base of Q9 goes high, Q9 turns on, SB SW (Q2) turns on and power (SB) is supplied to the set. This circuit has an overvoltage protection circuit. If a DC voltage of 20 V or higher is applied to the power cable, D2 turns on and a voltage is applied to the base of Q2.
