I TO SERVICE PERSONNEL

. AC LEAKAGE
1. Critical Components Information. WALL EQUIPMENT TESTER OFl
Components having special characteristics are marked and OUTLEI' UNDER TEST EQUIVALENT
must be replaced with pans havlng specifications equal to
those originally installed. ® :3..-
2. Leakage Current Measurement (For 120V Models Only).
When service has been completed, it is imperative to verity E =
that all exposed conductive surtaces are properly insulated IEASBLLHEATWG
from supply circuits.
0 Meter impedance should be equivalent to 1500 ohm shumed 0 Leakage current must not exceed 0.5mA.
by 0.15uF.

0 Be sure to test for leakage with the AC plug in both
polarities.

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

QUALIFIED SERVICE PERSONNEL.

PROTECTION OF EYES FROM LASER BEAM DURING SERVICING

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
0 Material - : GaAlAs eyes more than 30 cm away from the objective lens.
0 Wavelength 2780 nm
0 Emission Duration: Continuous
0 Laser Output : max. 44.6 uW"

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