CT-70 Adjustment Procedure 1. Adjust the DC power supply so that 3V 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 762.5MHz,775MHz and 787.45MHz. eface numb capacitance100P,0603.TDK capacitance102,0603.TDK capacitance103,0603.TDK capacitance104,0603.TDK capacitance6P3,0603.TDK capacitance10P,0603.TDK capacitance4P7,0603.TDK capacitance1P5,0603.TDK capacitance3P,0603.TDK capacitance473,0603.TDK capacitance33P,0603.TDK capacitance303,0603.TDK capacitance470P,0603.TDK capacitance173,0603.TDK capacitance15P,0603.TDK capacitance27P,0603.TDK capacitance330P,0603.TDK capacitance47P,0603.TDK capacitance200P,0603.TDK capacitance222J,0805.TDK Ta capacitance10U/A Ta capacitance100U/A Ta capacitance0.47U/A Ta capacitance1U/A Ta capacitance47U/A audionBAV99W,SOT-23 audionBAT54C,SOT-23 diodeRB051L, switch RS-282G02A1-SM inductance220N,0603 inductance82N,0603 inductance22N,0603 inductance7.5N,0603 inductance470UH quadrode BFG520/X, SOT- 143B audion 2SA1037AK, SOT- 23 audion2SC2412K, SOT-23 audion2SK208, SOT-23 audionXR151, SOT-23 audion XP162A, SOT- 89 resistance220R,0603.TDK resistance6.8K,0603.TDK resistance47K,0603.TDK resistance10R,0603.TDK resistance1K,0603.TDK resistance22R,0603.TDK resistance100R,0603.TDK resistance15K,0603.TDK resistance4.7K,0603.TDK resistance10K,0603.TDK resistance100K,0603.TDK resistance47R,0603.TDK resistance470R,0603.TDK resistance1M,0603.TDK resistance2.2K,0603.TDK resistance470K,0603.TDK resistance22K,0603.TDK resistance270R,0603.TDK resistance270K,0603.TDK resistance3.9K,0603.TDK resistance150K,0603.TDK resistance18K,0603.TDK resistance560K,0603.TDK resistance1.2K,0603.TDK resistance220K,0603.TDK resistance12K,0603.TDK resistance33K,0603.TDK resistance330R,0603.TDK resistance1.5K,0603.TDK ICHT7130,SOT-25 ICHT7150,SOT-25 ICMB15E03L ICLMV321 ICSA575,SO-20 ICJR4580 IC24C01,SOP-8 ICHT46R23A-1 ICHT1621B ICXC6367B adjustable capacitance VC2-6P VCO VCO805 adjustable resistance VR10K adjustable resistance VR1K adjustable resistance VR50K firm tube 3V,SOT-23 PCB U-800-P01B6.8*7.1 PCB U-800-P02B6.8*7.1 U-800-P01B6.8*7.1 U-800-P02B6.8*7.1 resistor4M,49-U resistor shield box886 connector2*14P displayM10230 case connector4P antenna socketBMC 240 battery 105-++-SET 780 transmiter box antenna point platic slip PVC sticker PVC PVC PVC sticker PVC ANT PVC sticker PVC GAIN PVC sticker PVC SET sticker sticker screw 2.6*10PA screw 2.3*4KB PO poly bag
