TO SERVICE PERSONNEL

WARNING: Laser Safety

This product contains a laser beam component. This component may emit invisible, as well as visible radiation,
which may cause eye damage. To protect your eyes and skin from laser radiation, the following precautions must
be used during servicing of the unit.

1) When testing and/or repairing any component within the product, keep your eyes and skin more than 30 cm away from

the laser pick-up unit at all times. Do not stare at the laser beam at any time.

2) Do not attempt readjustment, disassembly or repair of the laser pick-up, unless noted elsewhere in this manual.

3) CAUTION : Use of controls, adjustments or performance of procedures other than those specified herein may result in

hazardous radiation exposure.

Laser Emitting conditions:

1) When the Top Cover is removed, and the POWER 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 set, 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.
