3.4.5. RANDOM Mode
RANDOM mode is a trigger mode where each time a trigger is input, only a predetermined
number of frames are saved to memory. For example, this function is convenient for a
photographic subject which is an irregular and repeated phenomenon which can have a trigger
output produced for each cycle or occurrence. The number of frames recorded each time the
trigger is input can be set as desired, in one frame increments, from one frame to the maximum of
all the recordable frames available.
■ Setting RANDOM Mode (Frame Count)
To use RANDOM mode, the number of frames to save each time the trigger is input must be set
in advance before recording. The procedure for making that setting is explained next.
1. Press the MENU key on the keypad and the menu list will display.
2. With the ARROW keys on the keypad, select RANDOM FRAME from the RECORD
submenu and confirm with the ENTER key.
