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 REA-
SON 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. 1. Critical Components Information
Components having special characteristics are
marked s 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 prop-
erly insulated from supply circuits.
Meter impedance should be equivalent to 1500 ohms
shunted by 0.15µF. Leakage current must not exceed 0.5mA.
Be sure to test for leakage with the AC plug in both
polarities.

Laser Emitting conditions:
1) When the Top Cover is removed, and the STANDBY/ON SW is turned to the "ON" position, the laser component will emit
a beam for several seconds to detect if a disc is present. During this time (5-10 sec.) the laser may radiate through the
lens of the laser pick-up unit. Do not attempt any servicing during this period!
If no disc is detected, the laser will stop emitting the beam. When a disc is loaded, you will not be exposed to any laser
emissions.
2) The laser power level can be adjusted with the VR on the pick-up PWB, however, this level has been set by the factory
prior to shipping from the factory. Do not adjust this laser level control unless instruction is provided elsewhere in this
manual. Adjustment of this control can increase the laser emission level from the device.
