Bardzo dobra jakość skanu, przystępna cena. Instrukcja serwisowa okazała się przydatna przy "reanimowaniu" dwudziestoparoletniego decka, który teraz pięknie gra :)
1. Connect a regulated dc power supply (1.5 V) and ampere meter. 2. Set the [RF CHANNEL] switch (SW1) to [1]. 3. Check that the value of ampere meter satisfy specified value. Specified value: 50 mA to 65 mA 2. RX Frequency Adjustment Setting:
CT1 VCO Voltage Adjustment shield case
digital voltmeter +
lead wire antenna (ANT1)
� TX BASE BOARD � (Conductor Side)
FM RF SSG
� Foot of VCO lead wire board shield antenna (ANT1) case
Procedure: 1. Connect the 1/4 λ sleeve antenna to a SSG, and put the antenna by the lead wire antenna (ANT2). 2.

Connect a digital voltmeter to the TP51 on RX BASE board and the foot of FE board shield case. Connect REC out plug (P1) to an oscilloscope. Set the [RF CHANNEL] switch (SW1) to [1]. Adjust CT1 on the RX BASE board so that the value of digital voltmeter becomes 1.4 V. Confirm that the waveform of oscilloscope is sine wave. Change the carrier frequency of SSG to 864.2 MHz. Change the [RF CHANNEL] switch (SW1) to [2]. Adjust CT2 on the RX BASE board so that the value of digital voltmeter becomes 1.4 V. Confirm that the waveform of oscilloscope is sine wave. Change the carrier frequency of SSG to 864.6 MHz. Change the [RF CHANNEL] switch (SW1) to [3]. Adjust CT3 on the RX BASE board so that the value of digital voltmeter becomes 1.4 V. Confirm that the waveform of oscilloscope is sine wave.
