WARNING
WARNING:
TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK,
DO NOT EXPOSE THIS APPLIANCE TO RAIN OR
MOISTURE.
CAUTION:
TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT
REMOVE COVER (OR BACK). NO USER-SERVICEABLE
PARTS INSIDE. REFER SERVICING TO QUALIFIED
SERVICE PERSONNEL.
The lightning flash with arrowhead symbol, within an equilateral
triangle, is intended to alert the user to the presence of uninsulated
ìdangerous voltageî within the productís enclosure that may be of
sufficient magnitude to constitute a risk of electric shock to persons.
The exclamation point within an equilateral triangle is intended to alert
the user to the presence of important operating and maintenance
(servicing) instructions in the literature accompanying the appliance.

AVIS
This unit contains a semiconductor laser system and is classified as a
"CLASS 1 LASER PRODUCT". So, to use this model properly
, read
this Instruction Manual carefully.In case of any trouble, please contact
the store where you purchased the unit.To prevent being exposed to the
laser beam, do not try to open the enclosure.
CAUTION:
VISIBLE LASER RADIATION WHEN OPEN AND INTERLOCK
FAILED OR DEFEATED. DO NOT STARE INTO BEAM.
CAUTION:
THIS PRODUCT UTILIZES A LASER. USE OF CONTROLS OR
ADJUSTMENTS OR PERFORMANCE OF PROCEDURES OTHER
THAN THOSE SPECIFIED HEREIN MAY RESULT IN
HAZARDOUS RADIATION EXPOSURE.
The label on the right is
applied on the rear
panel except for USA
and Canadian models.
1. This unit is a CLASS 1 LASER PRODUCT and employs a laser
inside the cabinet.
2. To prevent the laser from being exposed, do not remove the
cover. Refer servicing to qualified personnel.

LASER CAUTION
LASER DIODE
Never look at the laser light beam through the objective lens. The visible laser beam may harm
the human eye. Use an appropriate viewer or TV camera to observe the laser beam.
Any laser diode will be damaged by a large current or pulse. Avoid current surges and
electrostatic discharges. Safety grounding of the human body and all measuring equipment, jigs
and tools is absolutely necessary. The use of a grounding mat on the workbench and floor is
necessary. Even a small electrostatic discharge from the human body may destroy the laser
diode instantaneously or reduce its life time.
The pins of the laser diode may be shorted at the factory by a solder bridge at the FPC for
protection during transportation and storage of the unit. If this is the case, open the short circuit
(accessible from the bottom side of the module) quickly with grounded soldering iron (less than
300ÞC).
The damage of the diode might be indicated by an increase of the laser current.
