LIST
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 designate components in which safety can be of special significance. When replacing a component identified ~, use only 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.
Regular type resistors and capacitors are not list. To know those values, refer to the schematic diagram.
CAUTION:

PRECAUTIONS
(CD)
Do not look straight at the laser beam from the pickup and do
not point the beam at your fingers or any other part of your
body.
Note: The laser beam must never be allowed to enter the eyes
since this may damage the eyes.
Power must never be supplied to a pickup with a damaged laser
output part (objective
lens, etc.).
