pa den optiske pick-up enhed. | tilfeelde af at det er
ngdvendigt at kontrollere udsendelsen af laserlys, skal
det ske i en afstand af mere end 25cm fra den optiske
pick-up.
2. Adskil aldrig den optiske pick-up enhed under
service, og juster ikke APC kredslobet (Automatic
Power Control). Hvis APC kredslobet (incl. laser-
dioden) bryder ned, skal hele den optiske pick-up
enhed (incl. APC printkortet) udskiftes.
