To synchronize the flash with the input of an external trigger, use the [REMOTE] connector on
the rear.

Ⅲ When the shutter mode is other than “RANDOM” “EEI” ( ੬ page E34, SHUTTER item)
● In response to the trigger input, the KY-F1030 outputs a flash signal for the CCD accumulation
period of the next frame.
● The image shot at the moment that the FLASH signal is outputted is output as the next frame.
● In the case of digital output, output stops with shooting of this frame and the image on the
PC’s monitor will be in the FREEZE condition.
● How to cancel the FREEZE condition can be selected. ( ੬ page E40, [FRZ CANCEL] item)
● The trigger interval must be minimum 3 frames (405 msec) at a shutter speed of 1/7.5 s or
faster.
● When the FREEZE cancel mode is set to “MANUAL”, FLASH will not be output in response to
the trigger input for FREEZE cancellation.

MEMO
• During output of the FLASH signal, the [FREEZE] indication will appear momentarily on the com-
puter monitor. If it is preferred that the indication is not shown, set the [FRZ DISPLAY] item to “OFF”.

Ⅲ When the shutter mode is “RANDOM”
• CCD accumulation is performed in sync with the trigger input, and this period is output as the
FLASH signal.
• At the same shutter speeds the delay from the trigger input to the FLASH output is almost
uniform as shown in Table A below. Also, the pulse width of the FLASH output differs with the
shutter speed.
• The trigger input interval is restricted as shown in Table B. Do not input at a shorter
interval than the minimum interval shown in the table.
MEMO
• In the condition where the shutter mode is RANDOM, the image quality may deteriorate at the time of
FREEZE as noise may be applied or white spots may appear.

* In the following situations, the FLASH signal is continuously generated in sync with the CCD
regardless of the external trigger.
● When [SHUTTER] on the EXPOSURE screen is set to “EEI”.
● When [GAIN] on the EXPOSURE screen is set to “ALC”.
● When [IRIS MODE] on the EXPOSURE screen is set to “AUTO”.
● While AW (Auto White) is operating.
