*1 This is an external input signal. Make sure to input
both HD and VD signals in this case. Input the
signal so that the VD phase aligns with the HD
falling edge.
*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.
