AUTO POWER OFF

To conserve battery power, the flash unit automatically turns itself off when the flash is not used within

approximately 90 seconds. To turn the flash on again, depress the TEST button or the camera shutter

button halfway. Please note that the “Auto Power Off” mechanism does not work with wireless TTL

flash mode, normal slave flash, and designated slave flash modes.

ERROR INDICATION

If the battery power is not sufficient or there is an electric information error between the camera and

flash unit, the “Flash Coverage Angle” will blink on the LCD panel. When this occurs, turn the power

switch off and on.

If it still blinks after this procedure, check the battery power.

ADJUSTING THE FLASH HEAD

Depress the Bounce “Up and Down” Lock and Release Button and

adjust the flash head to the desired position.

◆ If

appears on the LCD panel when you turn on the flash, and

if this mark blinks, then the flash head is adjusted to an incorrect

position.

ATTACHING AND REMOVING THE FLASH TO AND FROM THE CAMERA

Be sure to turn off the Power Switch, then insert the

Shoe Base into the hot shoe on the camera and turn

the Shoe Locking Ring until it is tight.

◆ When you attach or remove the flash, grasp the

bottom of the flash to prevent damage to the shoe

foot and the camera’s hot shoe.

◆ If the camera’s built-in flash is set in up position,

please close it before you attach the flash unit.

◆ To remove the flash, rotate the shoe-locking ring in

the opposite direction of ◄LOCK mark, until it stops.

SETTING OF FLASH COVERAGE ANGLE

When you press the ZOOM button,

the

symbol appears. Each time you press the ZOOM button,

the LCD panel display will change and indicate the zoom position in sequence as follows.

24mm → 28mm → 35mm → 50mm → 70mm → 85mm → 105mm → (Auto)

Generally, in the ETTL (TTL) mode, the flash will automatically set the zoom position according to the

focal length of your lens.

◆ When you turn on the main switch, the flash will memorize and set the zoom head position to the

last setting used.

◆ If you use a lens wider than the flash head setting, there may be under exposed areas around the

edge of the picture.

◆ Depending on the flash head setting, the flash’s Guide Number will be changed.
