PRODUCT SAFETY NOTICE

EACH PRECAUTION IN THIS MANUAL SHOULD BE FOLLOWED DURING SERVICING. COMPONENTS IDENTIFIED WITH THE
IEC SYMBOLA IN THE PARTS LIST AND THE SCHEMATIC DIAGRAM DESIGNATE COMPONENTS IN WHICH SAFETY CAN
OF SPECIAL SIGNIFICANCE. WHEN REPLACING A COMPONENT IDENTIFIED , USE ONLY THE REPLACEMENT PARTS
DESIGNATED, OR PARTS WITH THE SAME RATINGS OF RESISTANCE, WAITAGE 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.

CAUTION :

Regular type resistors and capacitors are not listed. To know those values, refer to the schematic diagram.
Regular type resistors are less than l/4W carbon type and Oohm chip resistors.
Regular type capacitors are less than 50V and less than 1000pF of Ceramic type and Electrolytic type.
