SAFETY PRECAUTION FOR SERVICE MANUAL
WARNINGS (MD)
The AEL (ACCESSIBLE EMMISSION 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.

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.

PERFORMANCE OF PROCEDURES OTHER THAN THOSE
SPECIFIED HEREIN MAY RESULT IN HAZARDOUS
RADIATION EXPOSURE.
VARO !Avattaessa ja suojalukitus ohitettaessa olet alttiina näkymättömälle lasersäteilylle. Älä katso säteeseen.
VARNING! Osynlig laserstralning när denna del är öppnad och spärren är urkopplad. Betrakta ej strälen.
Precaution to be taken when replacing and servicing the laser
pickup.
The following precautions must be observed during servicing to
