Additionla Laser Caution
Transistors Q1101 and Q1102 in PCB drive the laser diodes for DVD and CD
respectively. When Q1101 or Q1102 is shorted between their terminals,
the laser diodes for DVD or CD will radiate beam. If the top cover is removed
with no disc loaded while such short-circuit is continued, the naked eyes may
be exposed to the laser beam.
