-CD Player Service Precautions

1. For pickup unit(CXX1311) handling, please refer

to"Disassembly"(see page 52).

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 con-

nector is plugged or unplugged.

3. Please checking the grating after changing the ser-

vice pickup unit(see page 46).

-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)
