IMPORTANT

THIS HITACHI APPARATUS CONTAINS

LASER OF CLASS 1.

SERVICING OPERATION OF THE APPARATUS

SHOULD BE DONE BY A SPECIALLY

INSTRUCTED PERSON.

LASER DIODE CHARACTERISTICS

MAXIMUM OUTPUT POWER : 7 mw

WAVELENGTH : 650 nm

Additional Laser Caution

1.Inside detection switch (S201 on the INSB assy) and loading-

status detection switch (S301 on the LOSB assy) are detected

by the microprocessor (IC501 in the DVDM assy).

• To permit the laser diode to oscillate, it is required to set the

inside detection switch for the inside position (S201 : ON) and to

set the loading-status detection switch for the clamp position (the

center terminal of S301 is shorted to +5V). The laser diode

oscillation will continue if pin 13 of IC101 is shorted to +5V (fault

condition) in the DVDM assy.

In the test mode ∗, the laser diode oscillates when microproces-

sor detects a PLAY signal, or when the PLAYkey is pressed

(S107 ON in the FLKB assy), with the above requirements satis-

fied.

2.When the cover is open, close viewing through the objective lens

with the naked eye will cause exposure to the laser beam.

∗: Refer to page 40.
