- CD Player Service Precautions
1. For pickup unit(CXX1235) handling, please refer
to"Disassembly"(see page 46).
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.
3. Please checking the grating after changing the ser-
vice pickup unit(see page 31).
4. The doors CAT2248 and CAT2305 have been engaged
each other tightly. When you have to replace the
door CAT2248 or CAT2305, remove both doors from
the Grille to replace them at the same time.
