Basic Functions Power on Turn the power switch clockwise/volume control knob to turn on the radio. The sound "beep", if the voice function turning on, and reports the current channel number. Channel Selection Switch the channel rotator to the demanded channel.if turning on channel report (programmed by PC),then hear the channel No. VOX Adjust Press [MONI] and rotating the VOX to adjust the suitable at same time. Transmitting Press PTT and Red Indicator flashes, then transmitting the information and release. Monitor Short press (FM/Monitor/FM+) to turn on the Squelch Function, press gain to turn off. Call Function Press (PTT) and (FM/Monitor/FM+) simultaneously to call and transmit, release (FM/Monitor/FM+) to quit. FM Operation 1.Long press Keys SK1(FM/Monitor/FM+) for more than 2 seconds and hear the sound beep, turning on the FM.The radio can scan automatically by short pressing the (FM/Monitor/FM+) Keys 11
SK1 or Keys SK2.Stop scanning when get a signal If want to receive another radios, short press (FM/Monitor/FM+) or Keys SK2 again. 2. Long press (FM/Monitor/FM+) for more than 2 seconds and hear the sound beep,beep means to quit the FM. 3. Closing the FM function can be programmed by PC. Note: The radio can return automatically to be ready for transmitting when receiving the same frequency signal.if set on it, radio can return and go on receiving FM after communication for 5 seconds. If not, the radio can not return automatically. Scan Function When activate the scan function by PC program, and turn to the Channel 16, then radio tips the sound of scanning. If report 16, it means to turn off the scan function. Turning on the scan function and being standby,radio would scan the signal one by one from the present channel. When match with same signal,led light would flash green and receive signals.then you can transmit the information by PTT.If there is no operation on the radio for 10 seconds,it would return to scan. Example: When activate the scanning of Channel 3,5,7,radio would scan automatically when get to Channel 16.Once receiving the signal from anyone of channel 3,5,7,16,scanning would stop and ready for transmitting. 12
Channel Lock Out Radio with channel lock out function avoids not transmitting by some improper operation on the radio at some specific occasions. Steps: Press Keys SK1(FM/Monitor/FM +) and Key SK2(FM-) at the same time to turn the radio on, and beep tips sound. It means changing present status. It is only allowed to use one channel and can not be changed by Channel Selector when active Channel lock out function. Do again the above steps to turn to Channel 16. Low Battery Alert 1. Working in Voltage higher 6.5 V 2. Transmit and receive working,but red indicator flashes when voltage lower than 6.3V,but higher than 5.8V (Battery shows 1 Grid) alarm every 20 seconds. 3. Voltage lower than 5.8V, receive working, alarm every 2 0 seconds,but can not transmitting. Wired Cloning (Mutual clone between two transceivers) 1. Well connected the transmission lines to the both transceivers, and then power on the subsidiary transceiver. 2. Rotate the channel selector on the base transceiver to channel 8, then hold and Press Keys SK1 Radio/Monitor/FM+ key to power on, (3 seconds later) until the orange light (red light and green light flash simultaneously) flashes which indicates the base transceiver is in cloning state, then 13
release the button. 3. When the orange light on the base transceiver flashes, press the PTT key, the green light on base transceiver flashes, and the red light on subsidiary transceiver flashes, which indicates the base transceiver is in cloning state. The mutual clone is successful when the light on base transceiver flashes orange again. 4. If indicator lights of both two transceivers flashes abnormally in the process of data transmit, it means replication fail. In that case, please check and make sure the transmission line is well connected. And please press the PTT button again to resume cloning when the indicator light of the base transceiver shines orange. 5. If need to clone with more than one transceiver, please turn off the subsidiary device after cloning finished and then pull out the transmission cable. And then clone to next transceiver following steps by press PTT again. 6. Please reboot the transceiver to make it work properly after cloning. 14
Function Setting PC Software Programming Setting Please login in http://www.nanfone.com to download to NF-910 software. Or ask for the local distributors. SQL Setting 1. Open the PC software to select the squelch level you require on the right corner Squelch level is from 1-9. The higher the squelch level, the lower chance of interference, but it may affect the communication distance. 2.Squelch system can eliminate background noise when there is no signal received, which not only make it more comfortable at standby mode, but also significantly reduces the standby power consumption. VOX Function 1. Open the PC software, you can select the squelch you require, like the picture. The level of VOX is from level 1 to level 10. The higher the lever is, the higher the sensitivity will be. 2. VOX Postponement: If the transceiver returns to receiving mode immediately after launch, the end part of the call may not be transmitted correctly. Such kind of problem can be avoided by setting VOX Postponement. 15
TOT 1. Open the PC software programming to select the times. The purpose of the Time-out Timer is to prevent any single person from using a channel for an extended period of time. 2. The overtime can be set by PC software programming ( the time can set as 30 seconds, 60 seconds, 90 seconds 120 seconds 150 seconds 180 seconds or OFF ). If the continuous launching time is over the preset timer, the launching will be stopped and a Beep tone sounds. To stop the Bi tone, please release the PTT button. You can press the PTT button again to resume launching. Oral Channel Indicator Function Open the PC software to select the language. When the oral channel indicator function is programmed to be off, then the transceiver will not report the channel. When the oral channel indicator function is programmed to be in English or in Chinese, then the transceiver will report the channel accordingly. Scan Function 1. Open the PC software to select the scan should be turned on or not. 2. There re scan function options behind each channel if the function is selected. When the scan function is set to be ON, the channel can be scanned automatically in standby state, and you can talk on this channel while there s signal. Rotate the channel selector to channel 16 to activate the 16
scan function, and then those channels which set automatic scan will be activated by it-self. For instance, if the scan function of channel 3,5,7 was activated by PC software programming, when you rotate the channel selector to channel 16, the transceiver will scan channel 3,5,7,16, when receive signal from one of these four channels, it will stop scanning, and talk on this channel. It s normal that it will be delayed when you open the speaker after activating the scan function, the delay time is related to the number of channels which set scan function. Note: If the channel with CTCSS/DCS, if it is disturb by signal with CTCSS/DCS or not during scanning, the radio light will bright green and quit scan. The speaker is also without sound. It must wait for 10 seconds after the interference, which is normal. Busy Channel Lockout 1. Open the PC software to select the channel you require. NF-910 can be set to be OFF, carrier wave and QT/DQT busy lockout 2. CTCSS Busy Lockout: The transceiver receives SQ, but not QT/DQT, and then transmitting is allowed. The transceiver receives SQ, and QT/DQT and then transmitting is prohibited. 3. Carrier Wave busy lockout: The radio receives SQ and it is prohibited. Power Save Open the PC software to decide whether you select the power saves or not. When on is chosen, that means you the power save function being turned on. 17
FM Radio Open the PC software to decide whether you will select the FM radio or not. When on is chosen, that means you the function being turned on. Radio Return Open the PC software to decide whether you will select the Radio return function or not. When on is chosen, that means you the Radio return function being turned on. If not, the FM radio exit automatically after receives a signal. High and Low Power Selection Open the PC software to select the high/low power in the corresponding channel you are in. Broad Band and Narrow Band Selection Open the PC software to select the Broad Band /Narrow Band in the corresponding channel you are in. QT/DQT 1.Open the program software, select the channel what you want and under the QT, and set it into QT/DQT/off. 2.QT/DQT: The SQ can work and radio transmits information under the same QT/DQT. If both radios with same channel but different QT/DQT then the SQ can not work and only bright green light. 18
