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.
Danger of explosion if battery is incorrectly replaced.
Replaced only with the same or equivalent type recommended by the manufacture.
Discord used batteries according to the manufacture's instructions.
Danger of explosion if battery is incorrectly replaced.
Replaced only with the same or equivalent type.
Slide the tray out on the back of the
remote controller and insert the battery
with the (+) and () poles pointing in
the proper direction.
· Use a CR2025 (3V) lithium battery
only. Never use other types of battery
with this unit.
1. In the state of FAN being attached to the mother unit, the voltage of about 6 to 8 V is impressed between TEST
point (FAN1) on surface A of the base plate and adequate GND to confirm its operation by visual observation.
2. After product assembly, a waveform observation is conducted using oscilloscope while playing DVD on TEST
point (TEST1) in front of chassis hole on lower face and adequate GND to confirm the existence of operation
noise (pulse) shape.
- Method of FAN Operation Confirmation
- Inverter for LCD back light becomes a high voltage.
