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 [
B
] (VCR) button. The tape will be loaded into
the Deck Mechanism Assembly. Make sure the power
is on, connect JP278(S-INH) 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.
