The following precautions must be observed during servicing to protect your eyes against exposure to the laser.

Warning of possible eye damage when repairing:

It the AC adaptor or batteries are connected when the top housing (disc cover) of the unit is removed, and the PLAY key is
pressed, the laser will light up during focus access (23 seconds). (Fig. 3-1) During the operation, the laser will leak from the
