- 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.
