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
MAXIMUM OUTPUT POWER : 5 mW
WAVELENGTH : 780 – 785 nm
IMPORTANT
T H I S P I O N E E R A P PA R AT U S C O N TA I N S
LASER OF CLASS 1.
SERVICING OPERATION OF THE APPARATUS
S H O U L D B E D O N E B Y A S P E C I A L LY
INSTRUCTED PERSON.
Additional Laser Caution
1. Laser Interlock Mechanism
The position of the switch (S2401) for detecting loading
completion is detected by the system microprocessor, and the
design prevents laser diode oscillation when the switch is not
in LPS1 terminal side (when the mechanism is not clamped
and LPS1 signal is high level.)
Thus, the interlock will no longer function if the switch is
deliberately set to LPS1 terminal side. ( if LPS1 signal is low
level ).
In the test mode
∗
the interlock mechanism will not function.
Laser diode oscillation will continue, if pin 5 of AN22022A
(IC601) on the MAIN Assy is connected to GND, or else the
terminals of Q603 are shorted to each other (fault condition).
2. When the cover is opened, close viewing of the objective
lens with the naked eye will cause exposure to a Class 1
laser beam.
