*1 This is an external input signal.
*2 The shutter speed (Te) is determined by the setting
of the DIP switches.
For details, see page 23.
*3 Normal operation is resumed when the trigger
pulse width is 1/3 s or more. The trigger falling
edge restores external trigger shutter operation. At
this time, the 50 ms after the falling edge of the
trigger pulse is an external trigger input inhibition
area. There is no guarantee of operation for any
trigger input in this period.
*4 The internal VD signals are output as long as there
is no external input and the HD/VD signal
input/output switch of the mode setting DIP switch
on the rear panel is set to the down position (INT).

*5 An image is output when an internal VD signal
falls 10 ms or more after a trigger pulse rises (2
and 3 in the figure). If the period from the
trigger rising edge to the internal VD falling edge
(T in the figure) is under 10 ms, it is not defined
whether the image is output for the external VD
falling edge or the image is output for the next
external VD falling edge. (1 in the figure shows
that the image is output for the next internal VD).
In this case, see WEN since the image and WEN
make up a pair.
Note
An image is not output correctly when the next
trigger is input before the image for the previous
trigger has been output.
