ADJUSTMENTItemAdjustment pointAdjustment methodVCO P/D VoltageTC2(VCO Box)Adjust TC2 so that the voltage of TP3 is 2.3V on the receiving mode(RX)at 144.00MHz.VCO P/D VoltageTC1 (VCO Box)Adjust TC1 so that the voltage of TP3 is 2.0V on the transmission mode(TX)at 144.00MHzFrequencyTC2(Main Board)Set the unit in the transmission mode at 145.00MHz and adjust TC2.Power outputVR6(Hi)On "HI"position,turn VR6 for 50W output at 145.00MHz.VR7(Lo)On"LO"position,turn VR7 for 5W output at 145.00MHz.RF Power MeterVR4Turn VR4 so that three segments will light on "LO"position.DeviationVR3Input a signal of 1KHz/25mV into the MIC jack and adjust VR3 so thatyou obtain 4.9KHz/Dev in the transmission mode.MIC GainVR2Input a signal of 1KHz/4mV into the MIC jack and adjust VR2 so thatyou obtain 4.0KHz/Dev in the transmission mode.DiscriminationL-10Enter SSG input 1KHz/MOD+3.5KHz/Dev 60dBu.AdjustmentAdjust to maxmize the output wave.SensitivityL1-5.L-6-8Enter SSG input 1KHz MOD+3.5KHz/Dev.At 145.00MHz,adjust to maxmize 12dB SINAD sensitivity.SensitivityL-15-17,TC4-10Enter SSG input 1KHz MOD+3.5KHz/Dev.at 880MHzAt 880MHz,adjust to maxmize 12dB SINAD sensitivity.Subaudible ToneVR1 (Tone squelchOn the "ENC"mode at 146.00MHz,turn VR1 so that the deviation isDeviationboard)O.7KHz.(DR-119T)1750Hz ToneVR1 (Tone burstPressing Tone button at 145.00MHz,turn VR1 so that the deviation isDeviationboard)3.5KHz.(DR-119E)S-MeterVR1Turn VR1 so that the 1 begins to light.(SG output:3dBx EMF)Squelch SensitivityVR9Turn the squelch control fully clockwise and turn VR9 so that the(SG output:squelch will be closed at the SG output of-6dBy.-6dBy EMF)Upper Side ViewL8飘TC4!OCN1028o2TC0VR6 O VR4VB7O O OVR2L30>0L7TC5OVR300L15v9L40VCOOTP388oL6品0L788OL8-8-
