TM-610 Adjustment Description This mobile radio can be adjusted via programming software or manually. The manual adjustment procedures are listed below. (please refer to “test mode” and “adjustment mode” in Mobile Radio Mode. Tools: Radio Communication Test Set a set Spectrum analyzer a set 20A/30V power supply aset Wattmeter a set Signal line (with dummy load) a piece Procedures: 1. Download: ¾ Connect the mobile radio with PC via programming software and turn on the radio. ¾ Click “Download” on the software interface; ¾ Select your desired program and click “begin” to begin download; ¾ Click “Close" when the program is fully downloaded. ¾ Turn off the radio and plug the programming cable out. 2. Initialization: ¾ The necessary information hasn’t been imbedded into the Flash of the radio when it leaves the factory. So users need to adjust the frequency and initialize the radio before adjustment; ¾ Press [P2] to power the mobile radio on. Press [P4] when “DESINAO” is displayed; ¾ The LED on the control panel stops flashing when initialization process is finished. 3. Adjustment (Part of the adjustment items can be adjusted in conventional mode while other should be adjusted manually.) ¾ Turn on the mobile radio to enter conventional mode; ¾ Power your mobile radio off and press [PF1] to restart the radio to adjust other items. The channel number will be displayed on LED; ¾ Frequency chart:
TM-610V：136-174； VCO Adjustment Measurement Adjustment Item Condition Test Instrument Terminal Part Method Specifications/Remarks 1. Power supply 1. Power supply: 13.6 V DC Note: 1. This mobile radio only can be installed in a minus groundingpower system. Reverse polarity will cause the cable fuse to blow. Check the vehicle ground polarity before the installation to avoid wasted timeand effort. 2. IF DC power is to be controlled by the vehicle ignition switch, a switchrelay should be used to switch the positive power lead. The vehicle ignition switch then controls DC to the relay coil.。 1.CH：TX HI 6.0V±0.1V 2. VCO Latch voltage (TX) 2.CH：TX LO TC1Check ＞1.0V 1.CH：RX HI 6.0V±0.1V 3.
