Bardzo dobra jakość skanu, przystępna cena. Instrukcja serwisowa okazała się przydatna przy "reanimowaniu" dwudziestoparoletniego decka, który teraz pięknie gra :)
Documentation made available quickly and It is good quality. Thanks.

SECTION 2 ELECTRICAL ADJUSTMENTS
Note: The adjustments should be performed in the order given.
2-1. Transmission Frequency Check and Adjustment
Preparation:
AF OSC ATT + + � � 600 � AUDIO IN (J403: Lch) 1 kHz 40 mVrms + � TMR-RF950R Transmitter frequency counter
+ �
Procedure: 1. Turn OFF the noise filter switch (S401) on the TX-BASE board. 2. Enter 1 kHz 40 mVrms signal only to the Lch (J403) on the TX-BASE board. 3. Connect a rod antenna to the input of frequency counter, and adjust its length to about 8 cm. 4. Install the set in the vicinity of frequency counter, and check that the frequency on each channel is as specified value. Specified value:
CH1 CH2 CH3 913.0 MHz ± 100 kHz 914.0 MHz ± 100 kHz 915.0 MHz ± 100 kHz
5. If out of the specified value, adjust the frequency by rotating RV402 and RV403 on the TX-BASE board. 6. After adjustment, recheck the frequency on CH1, CH2, and CH3. Adjustment Location: TX-BASE board (See page 6.)
2-2. Degree of Modulation of Subcarrier (L � R) Check and Adjustment
Preparation:
AF OSC AUDIO IN (J403: Lch) 1 kHz 316 mVrms ATT TMR-RF950R + � + � 600 � Transmitter
