MD-MX30/MX30W

SAFETY PRECAUTION FOR SERVICE MANUAL(For MD-MX30W)

WARNINGS (CD)
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. THEREFORE IT IS IMPORTANT THAT THE
FOLLOWING PRECAUTIONS ARE OBSERVED DURING
SERVICING TO PROTECT YOUR EYES AGAINST EXPOSURE TO
THE LASER BEAM.
1-WHEN THE CABINET IS REMOVED, THE POWER IS TURNED
ON WITHOUT A COMPACT DISC IN POSITION AND THE PICKUP
IS ON THE OUTER EDGE THE LASER WILL LIGHT FOR
SEVERAL SECONDS TO DETECT A DISC. DO NOT LOOK INTO
THE PICKUP LENS.
2-THE LASER POWER OUTPUT OF THE PICKUP UNIT AND
REPLACEMENT SERVICE PARTS ARE ALL FACTORY PRE-
SET BEFORE SHIPMENT.
DO NOT ATTEMPT TO RE-ADJUST THE LASER PICKUP UNIT
DURING REPLACEMENT OR SERVICING.
3-UNDER NO CIRCUMSTANCES STARE INTO THE PICKUP LENS
AT ANY TIME.
4-CAUTION-USE OF CONTROLS OR ADJUSTMENTS, OR
PERFORMANCE OF PROCEDURES OTHER THAN THOSE
SPECIFIED HEREIN MAY RESULT IN HAZARDOUS RADIATION
EXPOSURE.
CAUTION
This MD Compact Component System is clas-
sified as a CLASS 1 LASER product.
The CLASS 1 LASER PRODUCT label is lo-
cated on the rear cover.
Use the MD Compact Component System only in
accordance with the instructions given in this
manual and do not attempt to interfere with the
interlock switch or make any other adjustment as
this may result in exposure to hazardous radia-
tion.

WARNINGS (MD)
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. Therefore it is
important that the following precautions are observer during
servicing to protect your eyes against exposure to the laser beam.
1) When the unit case cover is removed and LOADING SW (SW
1956) is turned on and then PLAY SW (SW 1954 mechanism
PWB) is turned on in a few second.
The laser will light for several second to detect a disk.
2) The laser power output of the pickup unit and replacement service
parts are all factory pre-set before shipment.
Do not attempt to re-adjust the laser pickup unit during replacement
or servicing.
3) Under no circumstances stare into the pickup lens at any time.
4) If laser optical unit becomes faulty, replace the complete laser
optical unit.
5) CAUTION-USE of controls or adjustments, or performance of
procedures other than those specified herein may result in
hazardous radiation exposure.
