- CD Player Service Precautions

1.For pickup unit(CXX1480) handling, please refer to"Disassembly"(see page 38).

During replacement, handling precautions shall be taken to prevent an electrostatic discharge(protection by a jumper-solder).

2.During disassembly, be sure to turn the power off since an internal IC might be destroyed when a connector is plugged or unplugged.

1.SAFETY INFORMATION

CAUTION

3.Please checking the grating after changing the pickup unit(see page 35).

4.In this product, because the memory capacity of the microcomputer is insufficient, the test mode is not installed. However grating of the pickup unit can be confirmed.
