DEH-5/XU/UC

CD Player Service Precautions

1. Before disassembling the unit, be sure to turn off the

power. Unplugging and plugging the connectors dur-

ing power-on mode may damage the ICs inside the

unit.

2. To protect the pickup unit from electrostatic dis-

charge during serviving, take an appropriate treat-

ment(shorting-solder) by referring to "the DISAS-

SEMBLY" on page 47.

3. After replacing the pickup unit, be sure to check the

grating.(See p.44.)

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.
