CONTENT
If the mechanism mode does not change to the next mode
within 4 seconds after the loading motor starts rotating in
the loading direction, [E : 41 : 00] is identified and the
power is switched OFF.
If the mechanism mode does not change to the next mode
within 4 seconds after the loading motor starts rotating in
the unloading direction, [E : 42 : 00] is identified and the
power is switched OFF.
When the take-up reel pulse has not been generated for
more than 3 seconds in the capstan rotating mode,[E : 04 :
00] is identified, the pinch rollers are turned off and
stopped, and the power is turned off.
When the supply reel pulse has not been generated for
more than 3 seconds in the capstan rotating mode, [E : 08 :
00] is identified and the pinch rollers are turned off and
stopped, and the power is turned off.
When the drum FG pulse has not been input for more than
4 seconds in the drum rotating mode, [E : 10 : 00] is
identified, the pinch rollers are turned off and stopped, and
the power is turned off.
When the capstan FG pulse has not been generated for
more than 2 seconds in the capstan rotating mode, [E : 20 :
00] is identified, the pinch rollers are turned off and
stopped.
CONTENT
If the operation has not been completed 3 seconds after the
cassette housing started the cassette ejection operation, [E
: 00 : A0] is identified, the cassette is taken in, and the
mode is switched to STOP the pinch roller OFF.
If the operation has not been completed 3 seconds after the
cassette insertion, [E : 00 : C0]n is identified, and the
cassette is ejected.
