CD PICKUP REPLACEMENT
PRECAUTIONS
To prevent damage caused by static electricity, the following procedures for grounding is required when opening
or repairing the unit.
1. Grounding for the human body
Be sure to put on a wrist-strap for grounding (with impedance lower than 106 Ω) whose other end is grounded.
The strap works to drain away the static electricity build-up on the human body .
2. Grounding for the work table
Be sure to lay on the table a conductive sheet (with impedance lower than 106 Ω) such as a sheet of copper
which is grounded.
3. As static electricity build-up on clothes is not drainded away, be careful not to let your clothes touch the unit.
4. The short-pad on the pick-up PCB of a spare part is short-circuited for protection during shipment. To open the
short circuit, remove the soldering quickly with a soldering iron whose insulation resistance is larger than
10MΩ after connection to a suitable APC circuit.

[Note] After the wire connector is
connected, desolder( short-pad).
