Other Functions

Auto Power Off

To save battery power, power will be turned off automatically after 90 sec. of idle use. Press
the camera's shutter button to turn on the Speedlite again.
* You can cancel the auto power off function. (p.15)

AF-Assist Beam

When you press the camera's shutter button halfway, the flash may fire repeatedly. This is
the AF-assist beam function that facilitates autofocus for dark scenes. Its effective range is
approximately 4m/13.1 ft.
This function is available when using the Speedlite with an EOS DIGITAL camera that has an
external flash control function. Depending on the camera model, note that the firmware may
need to be updated.

Modeling Flash

Pressing the camera's depth-of-field button will fire the flash continuously for 1 sec. This
enables you to see the shadow effects on the subject before flash shooting.
Do not fire the modeling flash more than 10 consecutive times. If you fire the modeling flash
10 consecutive times, allow the Speedlite to rest for at least 10 min. to avoid overheating and
deteriorating the flash head.
