■ TO SERVICE PERSONNEL

1. Critical Components Information. Components having special characteristics are marked Z

and must be replaced with parts having specifications equal to those originally installed.

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

● Meter impedance should be equivalent to 1500 ohm shunted

by 0.15µF.

● Leakage current must not exceed 0.5mA.

● 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.

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

CDX-E100

1. Laser Diode Properties

● Material : GaAlAs

● Wavelength : 780 nm

● Emission Duration : Continuous

● Laser Output : max. 44.6 µW*

* This output is the value measured at a distance of

about 200 mm from the objective lens surface on the Optical Pick-up Block.

2. When checking the laser diode emission, keep your eyes more than 30 cm away from the objective lens.

WARNING: CHEMICAL CONTENT NOTICE!

The solder used in the production of this product contains LEAD. In addition, other electrical/electronic and/or plastic (where applicable) components may also contain traces of chemicals found by the California Health and Welfare Agency (and possibly other entities) to cause cancer and/or birth defects or other reproductive harm.

DO NOT PLACE SOLDER, ELECTRICAL/ELECTRONIC OR PLASTIC COMPONENTS IN YOUR MOUTH FOR ANY REASON WHATSOEVER!

Avoid prolonged, unprotected contact between solder and your skin! When soldering, do not inhale solder fumes or expose eyes to solder/flux vapor!

If you come in contact with solder or components located inside the enclosure of this product, wash your hands before handling food.

■ ERROR MESSAGE

(1) If stopped by any cause, error message can be displayed by pressing the remote STOP key while pressing and

holding the panel STOP key, or by test mode command number 23. The player holds the latest error message in EEPROM. So even if stopped with no error, the latest error message can be displayed with same operation.
