-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 con-

nector is plugged or unplugged.

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.

For resistors and capacitors in the circuit diagrams, their resistance values or

capacitance values are expressed in codes:

Ex. *Resistors

Code Practical value

123 12k ohms

103 10k ohms

*Capacitors

Code Practical value

103 0.01µF

101/10 100µF/10V

The >mark found on some component parts indicates

the importance of the safety factor of the part.

Therefore, when replacing, be sure to use parts of

identical designation.

Symbol indicates a resistor.

No differentiation is made between chip resistors and

discrete resistors.

NOTE :

Symbol indicates a capacitor.

No differentiation is made between chip capacitors and

discrete capacitors.
