SECTION 1
SERVICING NOTES
The laser diode in the optical pick-up block may suffer electro-
static break-down because of the potential difference generated by
the charged electrostatic load, etc. on clothing and the human body.
During repair, pay attention to electrostatic break-down and also
use the procedure in the printed matter which is included in the
repair parts.
The
fl
exible board is easily damaged and should be handled with
care.
NOTE ON LASER DIODE EMISSION CHECK
The laser beam on this model is concentrated so as to be focused
on the disc re
fl
ective surface by the objective lens in tha optical
pick-up block. Therefore, when checking the laser diode emission,
observe from more than 30 cm away from the objective lens.
NOTE FOR THE 28-PIN CONNECTOR
Do not use alcohol to clean the 28-pin connector connecting the
front panel with the main body.
Do not touch the connector directly with your bare hand. Poor con-
tact may be caused.
