- CD Player Service Precautions
1. For pickup unit(CXX1311) handling, please refer
to"Disassembly"(see page 72).
During replacement, handling precautions shall be
taken to prevent an electrostatic discharge(protection
by a short pin).
2. During disassembly, be sure to turn the power off
since an internal IC might be destroyed when a connector is plugged or unplugged.
3. Please checking the grating after changing the service pickup unit(see page 64).
- When the Repair is Complete
When the repair is complete, make the CD mechanism
ready for transportation
implementing the following procedures:
1. Press the changer side 1 and 4 simultaneously to turn
the ACC on.
2. As the ACC is turned on, the disc indicator blinks in
red.
3. When the blinking is stopped, the mechanism is
ready for the transportation.
4. Attach the Transportation Bracket (CNC7878). Now
you can transport it.(See the figure below)
