PCC ID: ALH24613110 2,1033(c)(9) TUNING o:ALHECC ID:ALH2ss13110 TK—280 Tuning procedure Before attempting to tune the transceiver, connect the unit to a suitable power supply. Whenever the transmitter tuned, unit must be connected to a suitable dummy load, uniess the instruction specify otherwise. The speaker output connector must be terminated with a 4 Ohm dummy load at any time during the tuning and connected to an AC voitmeter and an audio distortion meter or a SINAD measurement at all the time during the tuning. Power sw on during "A" push to test mode [1—1} then push "S" to tuning mode. This #** mean using 3 numbers from CHANNEL NOB. 1 Transmitter section 1.1 Frequency adjustment Set test mode CH1,Push "S" to enter tuning mode, Sefect [FREQ*##] , then PTT on. 160.100MHz+50Hz. 1.2 TX High power adjustment Set test mode CH1,Push "S" to enter tuning mode, Select Hpow, Push "A" to 5 points. a) Select [L Hpow###] then PTT on 4.8W +0.1W. b) Push "C" to select [L2 Hpow***] then PTT on, push "B" after tuned. c) Push "C" to select [C Hpow +**] then PTT on, push "B" after tuned. d) Push "C" to select [H2Hpow###] then PTT on, push "B" after tuned. e) Push "C" to select [H Hpow###] then PTT on, push "S" to return test mode.
