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 flexible board is easily damaged and should be handled with
care.
NOTES  ON  LASER  DIODE  EMISSION  CHECK
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.
LASER DIODE AND FOCUS SEARCH OPERATION
CHECK
1. Turn POWER switch on with no disc inserted and make Func-
tion switch to CD position.
2. Open the lid for CD.
3. Turn on S901 as following figure.
4. Press the 
[     ]
 (CD) button.
5. Confirm the laser diode emission while observing the object-
ing lens. When there is no emission, Auto Power Control cir-
cuit or Optical Pick-up is broken.
Objective lens moves up and down three times for the focus
search.
