4.5.8. RANDOM MANUAL Mode
In the RANDOM MANUAL trigger mode, the camera records in the memory a preset
number of frames of images at each trigger, as in the case with the RANDOM CENTER
mode. The difference is that the RANDOM MANUAL allows for any number of frames
to be recorded before and after a trigger, while the RANDOM SENTER mode records
the same number of frames before and after a trigger. This mode is useful to record
images of events that take place at an unpredictable timing with output of a trigger
signal and that you wish to observe together with scenes preceding the it. The number
of frames to record at each trigger can be set any number from 1 (one) up to the total
number of available frames in the memory.
Setting Number of Frames and Triggers for RANDOM MANUAL Mode
The procedures for presetting the number of frames to record at each trigger and the
number of triggers to be given during a recording session are the same as the ones
used in the RANDOM CENTER trigger mode. See the previous Section 3.5.5
RANDOM CENTER Mode. After presetting these numbers, go to the following
procedure for RANDOM MANUAL mode setting.

To use your camera in the RANDOM MANUAL mode, you need to preset numbers of
frames to record before and after each trigger. Here is how to preset these numbers:
