M-950ED Adjustment Procedure 1. Adjust the DC power supply so that 4.5V is obtained at the battery terminals. 2. Turn the microphone ,checking first whole machine work electric current whether normal(<100 mA) 3. Confirm that dummy load and coumunication tester(HP8920A) are prepared. 4. use the HP8920A to measure the frequency.if the frequency error margin out +/-4 PPMs, If there is variable electric capacity in VC3 in modulator to adjust the frequency error. 5. Change different channel. Repeat the test., It will change the frequency to 766.5MHz,768.5MHz and 770.25MHz.
