PRODUCT SAFETY NOTICE
Each precaution in this manua! should be followed during servicing. Components identified with the EC symbol A\ in
the parts list and the schematic diagram designate components in which safety can be of special significance. When
replacing a component identified with A\, 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.
SAFETY INTERLOCK
The Digital Compact Disc Player reads the disc signal by
detecting the taser beam. It must be avoided for the human body
to directly receive the beam. Especialy human eyes are badly
affected by the beam. Therefore, the unit is equipped with an
interlock to prevent the unnecessary laser outputs.
The laser outputs are controled by the injection or cutoff of the
constant voltage source to the laser diode with Pin 16 of IC 901
(«PD75206G). When Pin 16 is in “L” (Low) level, the laser emits
the beam. When Pin 16 is in “H” (High) level, the laser does not
emit the beam.
Pin 16 is set in “H” level when the unit is loaded with the disc
and it reads the index signals or when the unit is set in the play
mode after that. When the unit reads the index signals and the
following two conditions are met, the laser emits the beam.
1) When the Loading Limit Switch is set in “ON”. (The disc is
set to the turntable.)
2) The pickup is located at the area of the minimum internal
circumference.
After the above conditions are met and the index signals have
been read, the laser emits the beam when the following two
conditions are met.
1. When the PLAY button is pressed.
2. When the PLAY indicator is ON.
