WARNING This product contains lead in solder and certain electrical parts contain chemicals which are known to the state of California to cause

B

cancer, birth defects or other reproductive harm.

IMPORTANT

The pickup of this device conforms to Class 3A of the FDA Laser Restrictions (CFR21 PART 1040), and the device, which conforms to Class A as a total product, is not to be disassembled for repair in the U.S.A. or its territories. In other districts, the device must be disassembled for repair only by a specially instructed person with sufficient care against laser light.

Additional Laser Caution

1. The ON/OFF(ON:low level,OFF:high level) status of the CLAMP signals for detcting the loading state are detected by the drive CPUs, and the design prevents laser diode oscillation when the CLAMP signal turns OFF. In normal operation, if no disc is clamped, the laser diode oscillation is disabled. However, the interlock does not always operate in the test mode.

*

2. When the cover is opened, close viewing of the objective lens with the naked eye will cause exposure to a Class 3A laser beam.

The Traverse & Main Unit-S, to be provided as service parts, have markings for distinction (black dot with a felt-tip marker) at the places shown in the photos below. Be sure to replace both the Traverse Mechanism Assy and MAIN Assy when either needs to be replaced, because these parts were adjusted as a pair, and their operations were inspected as a pair before shipment.
