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 pick-up 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.

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

protect your eyesvagainst exposure to the laser.

Warning of possible eye damage when repairing:
