*1 This is a signal input from outside. The trigger
input frequency must be [Shutter speed (DIP
switches) + 1 field + 2 H frequency] or more. If
invalid data is input, normal operation is resumed
several Vs after entering the correct data.
*2 The exposure time (Te) is determined by the
setting of the DIP switches.
For details, see Page 10.
*3 The normal operation state is chosen when the
trigger pulse width is 1/3 s or more. The trigger
falling edge restores the external trigger shutter
operation. In this case, the area between the falling
edge of a trigger pulse and the subsequent 50 ms
period is an external trigger input inhibition area.
There is no guarantee of operation for any triggers
input in this period.

trigger rising edge according to the DIP switch
setting.
