Using the Shutter Modes

4.3 Random Shutter (V Sync Reset)

On the rear panel mode switch SW3, set switch 1 to OFF and switch 2 to ON.

Use the shutter speed control switch SW1 to set the shutter speed. Figure 4–3

shows the random shutter speed control timing with V sync reset.

The random shutter operates only when the shutter command has been

added, so continuous shutter is the normal operating mode.
