9-1 Warning Indicators

9-1-1 Warning Indicators
The following five warning indicators are on the front
panel.
ALARM
indicator
MUTE
indicator
PB CONDITION
indicator
When the ALARM Indicator Comes On
When any abnormality occurs in the unit, this indicator
lights.
For error code numbers, see section 9-2 "Error Messages"
(page 9-2).
When the MUTE Indicator Comes On
If proper playback cannot be accomplished due to
damaged tape, abnormal tape recordings, or head drum
or other transport system failure, the unit is
automatically muted (silenced) and the MUTE
indicator illuminates. Even if the MUTE indicator
lights, it does not necessarily indicate machine failure.
However, if the indicator comes on frequently, you
should check the tape and the machine.

1)
CORRECTION
The system restores any error found in the playback signal
to normal using the error-correcting code.
When the PB CONDITION Indicator Comes
On
When the tape playback results are poor, in other
words, the error rate is high, and repetitive
interpolation or muting is about to begin, the PB
CONDITION indicator comes on. If the indicator
lights frequently, you should check the tape and the
machine. If an incorrect tape is used, copy its contents
to new tape without delay. Note that the "Pb cond"
(PB CONDITION) setup in the setup menu can be
changed to illuminate the PB CONDITION indicator
in either the CORRECTION
state. If CORRECTION is selected, the PB
CONDITION indicator will come on more frequently.
See section 7-3 "Dial Menu Operations" (page 7-5).
REC INH
indicator
SERVO lock
When the SERVO Lock Indicator Comes
indicator
On
When the head drum revolving speed builds up as
specified and the capstan reaches the steady-state
rotating speed (this state is referred to as being servo-
locked), the SERVO lock indicator comes on. In chase
synchronization mode, this indicator does not go on
until chase synchronization is achieved.
When the REC INH Indicator Comes On
This indicator lights when a write-protected cassette
tape (cassette tape with its tab hole open) or software
tape is inserted into the unit. While the indicator is lit,
the unit is inhibited from recording. To record onto a
write-protected tape, close its write-protect tab hole.
For the write-enabling procedure, see Section 3-4-2
"Preventing Accidental Erasure" (page 3-11).
2)
INTERPOLATION
If the error rate exceeds the error correction range, the
erroneous data are replaced by the average of the data
immediately before and after the erroneous data so as to
make the errors inaudible.
