LASER BEAM SAFETY PRECAUTION

• Pickup that emits a laser beam is used on this CD section.

CAUTION :
USE OF CONTROLS OR ADJUSTMENTS OR
PERFORMANCE OF PROCEDURES OTHER
THAN THOSE SPECIFIED HEREIN MAY RESULT
IN HAZARDOUS RADIATION EXPOSURE.

LASER OUTPUT................ 0.6 mW Max. (CW)

WAVE LENGTH ................. 790 nm

IC BLOCK DIAGRAM & DESCRIPTION

CAUTION-INVISIBLE LASER RADIATION WHEN OPEN AND
INTERLOCKS DEFEATED. AVOID EXPOSURE TO BEAM.

ADVARSEL-USYNLIG LASER STRÅLING VED ÅBNING, NÅR
SIKKERHEDSAFBRYDERE ER UDE AF FUNKTION, UNDGÅ
UDS ÆTTELSE FOR STRÅLING.

VARNING-OSYNLIG LASER STRÅLNING NÄR DENNA DEL
ÄR ÖPPNAD OCH SPÄRR ÄR URKOPPLAD. STRÅLEN ÄR
FARLIG.

VORSICHT! -UNSICHTBARE LASERSTRAHLUNG TRITT
AUS, WENN DECKEL GEÖFFNET UND ENN
SICHERHEITSVERRIEGELUNG ÜBERBRÜCKT IST. NICHT,
