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.

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 WENN SICHERHEITSVERRIEGELUNG
ÜBERBRÜCKT IST. NICHT, DEM STRAHL AUSSETZEN.

SCHEMATIC DIAGRAM(MAIN)

PRODUCT SAFETY NOTICE

Each precaution in this manual should be followed during
servicing. Components identified with the IEC symbol
in the parts list and the schematic diagram designated
components in which safety can be of special significance.
When replacing a component identified by
the replacement parts designated, or parts with the same
ratings of resistance, wattage or voltage that are designated
in the parts list in this manual. Leakage-current or resistance
measurements must be made to determine that exposed
parts are acceptably insulated from the supply circuit before
returning the product to the customer.
