MECHANICAL
OPERATION
CHECK
WITHOUT CASSETTE
When power is on, the general operations of the
mechanism
can be checked without a cassette.
Note the following points.
1. Check video search rewind and rewind, rotating
the take-up reel disk © by hand (in either
normal or reverse direction).
If it is not rotated,
the reel sensor works to shift the mechanism to
the eject mode.
2. When the stop button is pressed, the mechanism
does not stop at a normal stop position.
It shifts
to the eject mode and stops.
3. When the stop button is pressed in the playback,
video search rewind, and video search forward
modes, the supply reel disk © keeps on rotating
for several seconds for elimination of tape slack
in the course of shifting to the eject mode.
In
such a case, rotate the take-up reel disk ©
somewhat by hand, and the supply reel disk ©
stops, which can reduce the working time.
