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 flexible board is easily damaged and should be handled with
care.

The laser beam on this model is concentrated so as to be focused
on the disc reflective surface by the objective lens in the optical
pick-up block. Therefore, when checking the laser diode emis-
sion, observe from more than 30 cm away from the objective lens.

During normal operation of the equipment, emission of the laser
diode is prohibited unless the lid is closed while turning ON the
S895. (push switch type)
The following checking method for the laser diode is operable.

1. Open the lid.
2. Push the S895 as shown in Fig.1.
3. Check the object lens for confirming normal emission of the

laser diode. If not emitting, there is a trouble in the automatic
power control circuit or the optical pick-up.
In this operation, the object lens will move up and down 2
times along for the focus search.
