The P2 card is equipped with a write-
protect switch. If you set this switch to
the PROTECT position, no data can
be written to the P2 card and no
existing file can be deleted.

Prerecording and post-recording
Prerecording is the capability of including
material from an interval before the
specified start point in a recording.
Similarly, post-recording is the capability of
including material from an interval after the
specified stop point in a recording. The
intervals (prerecord time and post-record
time) can be set using the Toughbook-
Arbitrator Front End Software.
Audio recording can be disabled during
prerecord and/or post-record.
If recording is started
immediately after system startup
Prerecord time will be shorter.
If recording is started during
post-record interval
Post-recording will be terminated
and next recording starts. There is
no prerecording interval for the
second recording.

Post-record time
In the cases shown below, the actual
prerecord and post-record time may be
shorter than the respective setting.
Notes:
• If you press the REC button and
STOP button alternately in rapid
succession, the system may not
separate the two recording sessions,
resulting in a single video file.
• If the remaining capacity of the P2
card is low, the prerecord time or post-
record time may become shorter.
Notes:
• Any attempt to change the position
of the write-protect switch during
power-on will have no effect. To
produce the effect, turn the power
off and then turn it on again or
remove the card and then insert it
again.
• If the write-protect switch is set to
the PROTECT position on any of
the cards in the two card slots,
recording will not start.
