I TO SERVICE PERSONNEL

1. Critical Components lnlormation. WALL EQUIPMENT ¢Es$€i§A8§
Components havmg specual characteristics are marked and UNDER TEST EQUIVALENT

must be replaced with parts having specifications equal to OUTLET

those originally installed. ® I:

2. Leakage Current Measurement (For 120V Models Only). I-
When service has been completed. it is imperative to verify
that all exposed conductive surfaces are properly insulated INSULATING _
from supply circuits. TABLE

0 Meter impedance should be equivalent to 1500 ohm shunted
by 0.15uF.

o Leakage current must not exceed 0.5mA.
0 Be sure to test for leakage with the AC plug in both
polarities.

I
I CAUTION: USE OF CONTROLS OR ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER THAN THOSE
SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION EXPOSURE.

THE COMPACT DISC PLAYER SHOULD NOT BE ADJUSTED OR REPAIRED BY ANYONE EXCEPT PROPERLY
QUALIFIED SERVICE PERSONNEL.

l PROTECTION OF EYES FROM LASER BEAM DURING SERVICING

I This set employs a laser. Therefore. be sure to carefully
follow the instructions below when servicing .

1, Laser Diode properties 2. When checking the laser diode emission, keep your
. Material ; GaAIAs eyes more than 30 cm away from the objective lens.
0 Wavelength : 780 nm
0 Emission Duration : Continuous
0 Laser Output : max. 44.6 pW

* This output is the value measured at a distance
of about 200 mm from the objective lens
surface on the Optical Pick-up Block.

WARNING: CHEMICAL CONTENT NOTICE!
