When the camera receives the appropriate exposure, the ETTL (TTL) mark on the LCD panel will
appear for 5 seconds. If this indication does not appear, the flash illumination is not sufficent for that
situation. Please re-take the picture at a closer distance.
ۋ The AF Auxiliary Light will turn on automatically as you focus on a dark area. Note: Effective distance is
up to about 0.7 to 9 meter (2.3-29.5 feet).
ۋ When the camera is set to Creative Zone, please remember that the flash will be set to the last chosen
mode each time.
ۋ When the flash is fully charged, the flash mark will appear in the finder. If the shutter is released before

USING FLASH IN OTHER CAMERA MODES (Except EOS700, 750, 850)
Shutter Speed Priority Setting
By selecting the Tv mode of the camera, you can set the shutter speed from 30sec. to 1/X sync speed.
When you set the desired shutter speed, the camera will select the appropriate aperture value for the
background. If the subject is too light or too dark, the aperture value indicator will blink and show the limit
values (maximum or minimum aperture). In such as case, the camera proceeds to take flash photograph at
the limit value. Thus, the main subject in the picture may be exposed correctly, but the background will
become under or over exposed.
Aperture Priority Setting
By selecting the Av mode of your camera, the camera will select the appropriate shutter speed for the
background. If the subject is too bright or too dark, the shutter speed indicator will blink and show the limit
highest or slowest shutter speed value. The highest shutter speed will be limited to the camera’s normal
flash synchronization speed. In such a case, the camera proceeds to take a flash photograph at the limit
value. Thus, the main subject in a picture may be exposed correctly, but the background will become under
or overexposed.
When used with M Mode
You can set the desired shutter speed and aperture value. The sync speed of camera is 30sec. If you adjust
exposure according to the exposure meter indication, the camera will work as for Daylight synchronization
flash or slow synchronization.
LIMITS OF CONTINUOUS SHOOTING
To prevent overheating of the flash’s circuitry, please do not use your Flash unit for at least 10minutes after
using the number of flash exposures, shown in the below table have been made in quick succession.
Mode Number of Flash Exposures
TTL, M(1/1,1/2) 15 Continuous Flash Shots
M(1/4, 1/8) 20 Continuous Flash Shots
M(1/16-1/32) 40 Continuous Flash Shots
Multi 10 Cycle
MANUAL FLASH OPERATION
Manual flash is provided when shooting the subjects when the correct, Exposure is difficult to obtain in the TTL mode.
