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.

How to open the disc tray when power switch turns off 
Insert a tapering driver into the aperture of the unit bottom, and 
slide it in the direction of the arrow.

When installing a new OP unit, be sure to connect the wire (fl at 
type) (24 core) fi rst of all before removing the static electricity 
prevention solder bridge by unsoldering. 
Remove the static electricity prevention solder bridge by unsolder-
ing after the wire (fl at type) (24 core) has already been connected. 
(Do not remove nor unsolder the solder bridge as long as the OP 
unit is kept standalone.)

NOTES  ON  LASER  DIODE  EMISSION  CHECK
The laser beam on this model is concentrated so as to be focused 
on the disc refl ective surface by the objective lens in the optical 
pickup block. Therefore, when checking the laser diode emission, 
observe from more than 30 cm away from the objective lens.

On cleaning discs, disc/lens cleaners
•  Do not use cleaning discs or disc/lens cleaners (including wet 

or spray types). These may cause the apparatus to malfunction.

IMPORTANT  NOTICE
Caution: This system is capable of holding a still video image or on-
