NOTES ON HANDLING THE OPTICAL PICK-UP
BLOCK OR BASE UNIT
The laser diode in the optical pick-up block may suffer electrostatic
breakdown because of the potential difference generated by the
charged electrostatic load, etc. on clothing and the human body.
During repair, pay attention to electrostatic breakdown and also use
the procedure in the printed matter which is included in the repair
parts.
The flexible board is easily damaged and should be handled with
care.

Flexible Circuit Board Repairing
• Keep the temperature of the soldering iron around 270 ˚C during
repairing.
• Do not touch the soldering iron on the same conductor of the
circuit board (within 3 times).
• Be careful not to apply force on the conductor when soldering or
unsoldering.
Notes on chip component replacement
• Never reuse a disconnected chip component.
• Notice that the minus side of a tantalum capacitor may be dam-
aged by heat.

ELECTRICAL ADJUSTMENTS
http://getMANUAL.com
• FOCUS GAIN ADJUSTMENT
(COARSE ADJUSTMENT)
This adjustment is to be performed when replacing the following
parts.
•Optical Pick-up Block
•RV14
Procedure:
[RF BOARD] – Conductor Side –
CNJ12
IC51
RV14
1. Set RV14 (RF board) to the standard position.
2. Check that there is not an abnormal amount of operation noise
(white noise) from the 2-axis devise. If there is, turn RV14
slightly clockwise.
IC11
•When gain is lowered...
The set does not play because of no focus operation.
•When gain is highered...
Operation noise is heard due to a scratch or a dust, then operation will be unstable.
[RF BOARD] – Conductor Side –
MIN side
(low gain)
MAX side
(high gain)
