jedyne do czego mogę mieć zastrzeżenie to jakość zdjęć zawartych w przesłanej instrukcji serwisowej ponieważ są fatalnej jakości, praktycznie nieczytelne. tak poza tym jestem zadowolony to jest to czego szukałem.
Wszystko w porządku.
Instrukcja czytelna i kompletna.
Dziękuję.
all right!
thank you.

HANDSET SECTION
Note: � Apply 3.6 V dc from regurated DC power supply. � Perform the adjustment at TEST1CH (26CH: 43.780 MHz) as a rule. � Set to handset manual test mode. (Refer to page 9) TX SECTION ADJUSTMENT TX VT Adjustment Setting :
digital voltmeter
RX SECTION ADJUSTMENT RX LEVEL Adjustment Note: � Perform the adjustment at TEST1CH (26CH: 43.780 MHz) as a rule. Setting : VOL switch : M
FM RF signal generator
+ �
TP6 (TX VT) TP30 (TX GND)
TP2 TP3 (RX GND) Carrier frequency : 43.780 MHz Modulation : 1 kHz Deviation : FM 3 kHz Output level : 60 dBµV (1 mV) (EMF)
level meter
+ �
Procedure : 1. The digital voltmeter connected TP6 (TX VT) to TP30 (TX GND). 2. Adjust the L52 for 0.9 ± 0.05 V reading on the digital voltmeter. RX VT Adjustment Setting :
digital voltmeter
TP26 (SP) TP27 (SP)
Procedure : 1. Adjust the FL101 for the maximam reading on the level meter. Also check that the output level is the specified values. Specified Value : �9.5 to �15.5 dBV
+ �
TP5 (RX VT) TP3 (RX GND)
RSSI Hi Adjustment Note: � Perform the adjustment at TEST1CH (26CH: 43.780 MHz) as a rule. Setting :
AF oscillator FM RF signal generator
Procedure : 1. The digital voltmeter connected TP5 (RX VT) to TP3 (RX GND). 2. Adjust the L102 for 3.0 ± 0.05 V reading on the digital voltmeter.
Procedure : 1. Use the oscilloscope to confirm the FM RF signal generator input (AF) signal waveform and RSSI signal, and use the RV101 so that they are synchronized (duty is synchronized).
RSSI output waveform 0V Adjust so that they synchronize at 0 V. RSSI WAVEFORM
AF oscillator EXT signal 20 Hz
Adjustment Location : hand main board (See page 15)
