SANSIJI SE-300

CAUTION

1. Parts identified by the A symbol on the schema-
tic diagram and the parts list are critical for safety.
Use only replacement parts that have critical char-
acteristics recommended by the manufacturer.

2. Make leakage-current or resistance measurements
to determine that exposed parts are acceptably
insulated from the supply circuit before returning
the appliance to the customer.

NON MARK. . .Common Parts.

. Some printed circuit boards are not supplied as the assembled.
To separate these in this service manual, the stock Nos are not
indicated at the ends of the board names. However, the indi-
vidual parts on the circuit boards are provided by orders.

. Since some of capacitors and resistors are omitted from parts
lists in this service manual, refer to the Common Parts List for
capacitors & resistors, which was issued on February 1983.
