power of the laser diode exercise caution in order to
g
et safe, reliable results
.
Caut
i
o
n
:
1.
Durin

repair or tests, minimum distance of 13 cm from the focus lens must be kept
.
2.
Durin
g
repair or tests, do not view laser beam for 10 seconds or lon
g
e
r
.
WARNING!
The AEL (accessible emission 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.
A specially instructed person should do servicing operation of the apparatus.
Laser diode characteristics
Wave length:
DVD:640 nm to 660 nm
CD:770 nm to 810 nm
DVD : 2.48 mW(Emitting period :9 sec.)
CD : 705 W(Emitting period : unlimited)
Additional 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.
CAUTION
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.
