2. If lead solder must be used, be sure to remove lead free
solder from each terminal section of the parts to be replaced
and from the area around it completely before soldering, or
make sure that the lead free solder and lead solder melt
together fully.
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 to readjust, disassemble or repair 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 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.
