About Optical Sensors
Caution:
An optical sensor system is used for the Tape Start
and End Sensors on this equipment. Carefully read
and follow the instructions below. Otherwise the unit
may operate erratically.
What to do for preparation
Insert a tape into the Deck Mechanism Assembly and
press the [PLAY
B
] (VCR) button. The tape will be
loaded into the Deck Mechanism Assembly. Make
sure the power is on, connect S-INH (hollow) to GND.
This will stop the function of Tape Start Sensor, Tape
End Sensor and Reel Sensors. (If these TPs are
connected before plugging in the unit, the function of
the sensors will stay valid.) See Fig. 1.
Note:
Because the Tape End Sensors are inactive,
do not run a tape all the way to the start or the
end of the tape to avoid tape damage.
