*1 This is an external input signal. The trigger
interval should be trigger pulse width + 1 field +
2H period or more. The trigger interval shorter
than described above cannot be ensured. If a
trigger pulse is not input under the prescribed
conditions, the normal operation is ensured several
V after a change in input operation under the
prescribed conditions.
*2 Exposure time (Te)
Te = Trigger pulse width + 97 µ sec (EIA)
Te = Trigger pulse width + 120 µ sec (CCIR)
(The effective trigger pulse width for the external
trigger shutter operation is between 2 µ sec and
1/4 sec.)
*3 Normal operation is resumed when the trigger
pulse width is 1/3 sec or more. The trigger falling
edge restores external trigger shutter operation. At
this time, the 50 msec 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 A VD signal is generated 1H to 2H after a trigger
pulse falls, and an image is output in
synchronization with the VD signal.
*5 When the external trigger shutter mode changes
into the normal operation mode, a WEN signal is
output.
Note
An image is not output correctly when the next trigger
is input before the image for the previous trigger has
been output.
