3.2.1.4 Custom Trigger
If setting a positive number with the custom trigger, the number of frames recorded from the start of
recording to trigger input and the number of frames recorded from trigger input to the end of recording can
be setting as desired. The trigger timing can be set in 1% intervals.
Figure 3-8 shows a case when the trigger timing is set at +25%.

If setting negative numbers, it functions as a delay trigger.
For example, if the trigger timing is set as -100%, after trigger input, recording starts when the recording
possible time and the same time have elapsed.
