A transport screw has been attached to the set in order to protect
it during transportation. After removing the transport screw,
cover the hole with the supplied seal. Be sure to remove the
transport screw before mounting the set. The removed transport

-CD Player Service Precautions
1. For pickup unit(CXX1285) handling, please refer
to"Disassembly"(see page 44).
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 32).
4. Since these screws protects the mechanism during
transport, be sure to affix it when it is transported for
repair, etc.

Caution:
1. During repair or tests, minimum distance of 13cm from the focus lens must be kept.
2. During repair or tests, do not view laser beam for 10 seconds or longer.
2. A “CLASS 1 LASER PRODUCT” label is affixed to the
rear of the player.
3. The triangular label is attached to the mechanism
unit frame.
CLASS 1
