C12 : REC CH CONDITION
This menu displays the error condition for each channel in
three steps (GRN, YEL, and RED) when recording on the
tape recorded in Betacam SX format in the insert REC and
crash REC modes.
In the insert REC mode, checks using each PB signal from
the advance PB heads (A1, A5, B1, and B5) by tracking.
In the crash REC mode, checks using each PB signal from
the confidence PB heads (CNFA and CNFB).
m
. During normal operation, the tape is played back by non-
tracking. Therefore, the condition for each channel
cannot be checked using a CH CONDITION indicator.
. If abnormality exists in the servo system, this menu does
not function properly.
