-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.
