Recording Time Setup
Sound recordings initiated by markers will record for a user-
defined recording time following the initiation of the
recording. In addition, the user can select to have each
recording also include the sound signal which existed for a
user-defined time period prior to the initiation of the
recording, called the pre-trigger time.
Pre-trigger Time
The range of the manual recording
pre-trigger time is 0 to 9 seconds.
If it is desired that the recorded signal include a segment of
sound which occurred prior to the initiation of the recording,
set the Pre-trigger to the length of that time segment.
To enter the Pre-trigger Time, highlight the Pre-trigger data
field and press
5 to open the Pre-trigger Time data field
and cursor shown in Figure 16-12.
