Triax TR 212 Operating Manual page 21

(3) Timeshift:
Any of options, AUTO/OFF/ PAUSE, can be
selected to set the status of the current timeshift.
If AUTO is selected, the timeshift operation will
perform automatically in the background, the
user can change channel but this discards the
previous timeshift buffer and restarts a new one. If
OFF is selected, the timeshift operation will stop.
If PAUSE is selected, the timeshift operation will
manually start by pressing the 'Pause' key. The
screen freezes at once, it can be resumed by
pressing the 'Play' key. The timeshift buffer only
records the first channel; and if the preceding
three options are changed when AUTO is selected,
timeshift will restart.
(4) Timeshift Length:
The options, AUTO/30min/1h/2h, can be selected
to set the duration of the timeshift; if AUTO is
selected, the duration of the timeshift is dependant
on the available size of the USB memory. If any of
the options, 30min/1h/2h, are selected, the usable
duration of the timeshift is 30min/1h/2h provided
that the USB memory is big enough.
(5) Timeshift to Record:
Either of options, ON/OFF, can be selected. If
ON is selected, timeshift operation will stop and
the recorded file buffered by the timeshift will be
stored in USB memory; if OFF is selected, timeshift
will operate continuously and the recorded file
buffered by the timeshift will not be stored in USB
memory.
