-CD Player Service Precautions
1. For pickup unit(CXX1232) handling, please refer
to"Disassembly"(CX-597 Service Manual CRT1829).
During replacement, handling precautions shall be
taken to prevent an electrostatic discharge(protection
by a short pin).
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.
-This additional service manual is designed to be used together with Model YPM-1016ZF/UC Service
Manual CRT2111. Refer to it for finding parts numbers and adjustment, etc. which are not shown in
this manual.
