I. The ONIOFF statuses of the slider - position detection
switches (PARK INNER. PARK OUTER on the PKSB
assembly I, Ioading~ status detection switches (SW 1. 2 and 3
on PKSB assembly) are detected by the microprocessor
(ICIOI in the MOTHER ASSY )t To permit the laser diode to
oscillate. it is required to set the slider » position detection
switch for the LD ACTIVE status (PARK INNER: OFF, PARK
OUTER: OFF). and to set the loading - status detection switch
lot clamped state (SW1: OFF. SW2: 0N, SW3: ON )t 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 it pin 29 of Iceoi is shorted to GND or the emitter
and collector of 0509 are shorted each other (fault condition)

In test mode (see page 51 ). the laser diode oscillates when
microprocessor detects a PLAY signal or when the PLAY key
is pressed (5223: ON in the FLKY assembly), with the above

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