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.

Charged Section
The places where the commercial AC power is used without passing through the power supply transformer. If the places are touched, there is a risk of electric shock. In addition, the measuring equipment can be damaged if it is connected to the GND of the charged section and the GND of the non-charged section while connecting the set directly to the commercial AC power supply. Therefore, be sure to connect the set via an insulated transformer and supply the current.
High Voltage Generating Point
The places where voltage is 100 V or more besides the live parts are described above. You must not touch them, since there is risk of electric shock. The VSUS voltage remains for several minutes after the power to the unit is turned off. These places must not be touched until about 10 minutes after the power is turned off, or it is confirmed with a tester that there is no residual VSUS voltage. 1.

X CONNECTOR B Assy ............................... (�230V to 223V) Discharge the VSUS voltage, as shown below: [Method for discharging the VSUS voltage] 1. Set DRF_SW on the DIGITAL VIDEO Assy to ON (Drive OFF status). �1, �2 2. Leave the switch at that position for about 20-30 seconds. 3. If the power is on, turn it off. Then return DRF_SW to the OFF position. �3 Notes �1: You can also set the unit to "Drive OFF status" by sending the "DRF" RS232C command from the PC. �2: DRF_SW can be switched whether the power is on or off. �3: Power-down will occur if DRF_SW is set to OFF while the power is on.
