-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 ser-
vice pickup unit(see page 33).
