3 Unpacking and Installation Athough it is neither complicated to install nor difficult to operate your set, a few minutes of your time is required to read this manual for a properly wired installation and becoming familiar with its many features and how to use them. Please take a great care in unpacking your set and do not discard the carton and other packing materials. They may be needed when moving your set and are required if it ever becomes necessary to return your set for service. Never place the unit near radiators, in front of heating vents, in excessively humid or dusty location to avoid early damage and for your years of quality use. Connect your complementary components as illustrated in the following page. CAUTION RISK OF ELECTRIC SHOCK DO NOT OPEN This symbol is intended to alert the user to the presence of uninsulated dangerous voltage within the product s enclosure that may be of sufficient magnitude to constitute a risk of electric shock to persons. CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK. DO NOT REMOVE COVER (OR BACK). NO USER-SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL. Caution: This symbol is intended to alert the user to the presence of important operation and maintenance (servicing) instructions in the literature accompanying the appliance. To prevent electric shock do not use this (polarized) plug with an extension cord, receptacle or other outlet unless the blades can be fully inserted to prevent blade exposure. WARNING To prevent fire or shock hazard, do not expose the unit to rain or moisture. Attentions: Pour prévenir les chocs électriques ne pas utiliser cette fiche polarisée avec un prolongateur, une prise de courant on une autre sortie de courant, sauf si les lames peuvent étre insérées à fond sans en laisser aucune partie à découvert. * Do not install this apparatus in a confined space such as a book case or similar unit. * The apparatus shall not be exposed to dripping or splashing and no objects filled with liquids, such as vases, shall be place on the apparatus.

VOLUME This control is used for adjusting the variable output (4, 6 of rear panel). 3. UP/DOWN SWITCH When the switch is pressed one time, AM/FM frequency is up and down by one step. And in case of pressing continually, the frequency is up and down fastly. Also when the frequency is matched, it automatically stops. 4. FM/AM BAND SELECTOR This switch is used to select AM or FM. 5. MONO/ST This switch is used to select MONO/STEREO FUNCTION in FM. 6. TUNED This TUNED indicates tuning for absolute of AM and FM signals ensuring minimum distortion and maximum output. 7. MEMORY INDICATE (Number 10 Switch) This indicator is for memorizing the broadcasting frequency. 8. FM/AM BAND INDICATE (Number 4 Switch) This indicator is used for selecting AM or FM. 9. PRESET This indicator is display of the memory state. PT-9107S 3

6 10. MEMORY SWITCH This switch is for memorizing the broadcasting frequency. - Method 1 A. Select the frequency that you want to memorize by the UP/DOWN switch and press 4(memory switch). B. Press 4(memory switch) then select the desirable address when 13(address selector switch). C. Present status of tuner will be memorized in selected address. - Method 2 A. Select the frequency that you want to memorize by the UP/DOWN switch and press 4(memory switch). B. Press 4(memory switch) C. Present status of tuner will be memorized in 1 address. D. If A and B action repeat, present status of tuner will be memorized in next address. 11. PRESET/SCAN When the switch is pressed one time, memorized broadcasting can be listening sequentially during five seconds. (The status display at the Number 9 of LCD.) 12. MODE PRESET/TUNE When you press the UP/DOWN switch, MODE PRESET is increase and decrease by 1 channel. MODE TUNE is increase and decrease by 1 step. 13. ADDRESS SELECTOR SWITCH 20 kinds address are prepared and each address is accessible by this switches. 4 PT-9107S

8 Application of The Antenna - FM RECEIVING ANTENNA First of all, you have to connect FM antenna in the box. But, The electric wave of FM broadcasting is able to weaken in the case of hills and valleys, around buildings and in iron-reinforced buildings. - INSTALLATION OF ANTENNA EXCLUSIVELY FOR FM Listening to the broadcasting, fix the antenna after deciding the location and the direction so that the reception may be optimized. - INSTALLATION OF ANTENNA USING THE COAXIAL CABLE Noisy reception may occur in built-up areas and factory sites as well as around power cables. This may be the case even when an antenna is used exclusively for FM. In these regions, install the antenna using 75Ω coaxial cable. T-type ANTENNA /70 - INDOOR ANTENNA In the regions where FM broadcasting is heard comparatively well due to the near distance to the station or wooden structure, you can receive broadcasting of good quality by using T-type antenna.(using matching trans: 300Ω/75Ω) - AM LOOP ANTENNA Tuning the electric wave of AM broadcasting, you have to connect AM loop antenna in the box. Fix one end of AM loop antenna single cable to the AM terminal and the other end to GND. - AM OUTDOOR ANTENNA Install the vinyl-coated cable to an outdoor place if the AM reception is not good enough. 6 PT-9107S

9 Warning: Do not Install Antennas Near Power Lines or Service Entrances - THE FOLLOWING INSTRUCTIONS ARE FOR EXTERNAL ANTENNA INSTALLATION: Antenna System This receiver, tuner or tuner-amplifier is intended for connection to an antenna system, including outdoor antennas or community antenna television (CATV) systems, installed to provide some protection against voltage surges and built up static charges. Articles 810 and 820 of the National Electrical Code, ANSI/NFPA , provide information with respect to grounding of the mast and supporting structure, the lead-in wire to an antenna discharge unit, and the coaxial cable system; and with respect to the size of grounding conductors, location of antenna-discharge units, connection to grounding electrodes, and the requirements for the grounding electrode. If an outside antenna is connected to the antenna terminal of the tuner, be sure the antenna system is grounded in a manner similar to the accompanying Figure. (See Figure 67.1).
