I. The ONIOFF statuses oi the side-A/B detection switch

(TURN switch on the TNSB assy ), slider-position detection
switches ( INNER and OUYER on the PKSE assy ) and
loading-status detection switches (SW 1. 2 and 3 on the
LMSB assy] are detected by the microprocessor (ICIOI in
the MOTHER assy). To permit the laserdiooe to oscillate. it
is required to set the side-AID detection switch tor side A
status (TRN : OFF) and the slider-position detection
switcheslor the LD ACTIVE status (INNER : OFF, OUTER I
OFF). and to set the bedingatatus detection switches tor tilt
neutral stale (SWI : OFF, SW2 : OFF. SW3 : ON ), As long
as these requirements are not satisfied, the laser diode will
not oscillate. When the requirements are met in any way. the
laser diode can oscillate. The laser diode oscillation will
continue if pin 13 ol ICBOI is shorted to GND or the emitter
and collector of 0834 are shorted each other (lault
cond'nion ) in MOTHER essyr
In the test mode * , the laser diode oscillates when the
microprocessor detects a PLAY signal, or when the PLAY
key is pressed (SIM ON in the FLKY assy for Cu) - D790
or 8206 ON in the KEYB assy lor CLD - 0590 and CLD -
0390). with the above requirements satislied.

2. When the cover is open, close viewing through the obIective
lens with the naked eye will cause exposure to a Class 1
laser beam.
