The service manual when downloaded and printed out was clear and easy to read. I would have liked to have been able to enlarge some details, but this was not possible as the file permissions did not allow this. The service was very good. The time taken from placing my order to downloading the document was only a few minutes.

The manual is useful for trouble shooting for an old instrument. It saved money,and let me enjoy DIY.
;
Perfect source of information for replacing the HDD and performing general diagnostics.

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:
