Random Shutter (Fixed V Sync)

4.2 Random Shutter (Fixed V Sync)

On the rear panel mode switch SW3, set switch 1 to ON and switch 2 to OFF. Use the shutter speed control switch SW1 to set the shutter speed.

The random shutter operates only when the shutter command has been added, so continuous shutter is the normal operating mode.
