The ael (ACCESSIBLE EMMISSION LEVEL) of the laser
power output is less than class 1 but the laser component is
capable of emitting radiation exceeding the limit for class 1.
Therefore it is important that the following precautions are
observer during servicing to protect your eyes against exposure
to the laser beam.

(1) When the cabinet is removed, the power is turned on

without a compact disc in position and the pick-up is on the
outer edge the laser will light for several seconds to detect
a disc. Do not look into the pick-up lens.

(2) The laser power output of the pick-up unit and replacement

service parts are all factory pre-set before shipment.

Do not attempt to re-adjust the laser pick-up unit during
replacement or servicing.

(3) Under no circumstances stare into the pick-up lens at any

time.

(4) CAUTION-USE of controls or adjustments, or pereformance

of procedures other than those specified herein may result
in hazardous radiation exposure.
