If you use Once Timer, only one record will be
performed, which will start and end at the specified
date and record’s start and end time. For example,
December 31, 2011 at 23:50 recording starts, and
January 3, 2012 at 00:10 ends.
Recording will be carried out as long as the
Recorder has free memory and its battery charge
is enough to perform the operation.
Recording by timer can be stopped by pressing
Rec twice.
Circular Recording
The Recorder has the option of circular recording.
This method enables it not to stop recording when
the Recorder runs out of memory. After there is no
more free memory the Recorder begins to record
new data over old ones. Thus, the memory will
always contain the most recent records that are no
longer written off at the time of writing.
The user can devote to circular recording the
whole or only a part of the Recorder’s memory.
The volume of the memory specified determines
the duration of the resulting circular record.
