n Contrast Control Sync Mode

Refer to page 31 for the features and conditions of use of this

sync mode.

• Refer to “Connecting with the Extension Cord” on page 55

on using the flash unit detached from the camera.

1 Turn on the power switch (ON).

2 Press the Sync button (SYNC) to switch to contrast control

sync mode ( ).

3 Set the zoom position (flash coverage angle).

• The setting method differs according to your camera and

lens. (Refer to page 21.)

• If this flash unit is set in contrast control sync mode and is

much closer to the subject than the flash unit to be used

in combination, use manual zoom ( Zoom) to set the

zoom position to a shorter lens focal length.

4 Turn on the other flash unit to be used in combination.

• If the camera’s built-in flash unit is part of the

combination, pop up the built-in flash of the camera. In

combination, the flash output intensity ratio of the built-in

flash and the unit is 1:2. This means that the unit

discharges at double the intensity of the built-in flash.
