Very good manual, in depth and complete. Only criticism is that some of the circuit diagrams are slightly blurry and hard to follow for long periods of time, but this is to be expected. Perfect for any maintenance required. Also contains the wiring diagrams of the control cable for constructing extensions.

Received a quick response, material was exactly what it was supposed to be. The service did everything I expected it to do. would use service again.
;
Detailed SONY CFD980 Service Manual at an easy to find one stop shopping. Make my radio hobby technically interesting. Thanks.
 ;
Excellent service from Owner-Manuals.com, good prices and quick turn around. The supplied PDF was good enough quality to be enlarged sufficiently to read component values.

Very complete shop manual. It contains everything needed to troubleshoot bascially any problem. Instructions, diagrams, schmeatics, illustrations... it's all there. Highly recommended!

HANDSET SECTION
3. Checking TX output Setting:
peak power meter + � ANTENNA TERMINAL
� Make the set in Test mode (see page 24) 1. Checking RX I&Q Output Level Setting:
oscilloscope + � level meter + � TP520: RXIP TP521: RXIN TP522: RXQP TP523: RXQN TP553: GND
Procedure: 1. Place the handset in the Continuous Transmit mode (CH1, High power). 2. Measure the ANT OUT output of the RF module in the handset using a peak power meter. 3. Confirm that the measured output is 62 mW (MIN 25 mW). 4. Also, execute steps 1 through 3 for the channels 10 and 20. CH10: 64 mW (MIN 25 mW) CH20: 64 mW (MIN 25 mW)
SSG
ANTENNA TERMINAL
Procedure: 1. Place the handset in the Continuous Receive mode (CH1, LNA, AGC ON). 2. Set the SSG frequency to the frequency on CH1 + 300 kHz, and the RF output level to �95 dBm. 3. Measure the output level of RXIN, RXIP, RXQN, and RXQP with a level meter. At this time, confirm with an oscilloscope that a sine wave of 300 kHz is output. 4. Confirm that the measured output level is �25.0 to �19.0 dBV. If IC502 was replaced (there is no ID data), the output level is �30.0 to �24.0 dBV. 5. Also, execute steps 1 through 4 for the channels 10 and 20. * For the frequency on each channel, see page 18.
2. Checking TX Center Frequency Setting: � short: TP555 � TP553
frequency counter + � ANTENNA TERMINAL
Procedure: 1. Short TP555 and TP553 (GND) on the HAND MAIN board in the handset. 2. Place the handset in the Continuous Transmit mode (CH1, High power). 3. Measure the ANT OUT frequency of the RF module in the handset using a frequency counter. 4. Confirm that the measured frequency is 903.600 MHz ± 27 kHz. 5. Also, execute steps 1 through 4 for the channels 10 and 20.
