Manual Exposure Mode - Canon Speedlite 540EZ Manual

1. Manual Exposure Mode
Confirming the background exposure with the EOS-1 N and EOS-1:
— The main subject will be properly
exposed by the flash according to
the TTL program based on this
aperture value.
• Exposure warnings are given for the background exposure. For the meanings
of the warnings, refer to your camera's instruction book.
• The fastest flash-synchronizing shutter speed (X-sync speed) differs depend¬
ing on the camera model. Refer to the "X-sync Shutter Speeds for EOS
Cameras" chart on page 31.
• Even if you set a shutter speed that is faster than the camera's X-sync speed,
the camera will automatically reduce the shutter speed to the X-sync speed.
In this mode, you set both the shutter speed and aperture value as
desired. When a picture is taken, the camera and flash unit automatically
control the flash exposure according to the TTL program based on the
manually-set aperture value.
"| Set the camera's shooting
mode to manual exposure
mode (M), then set the
desired aperture value and a
shutter speed between 30
sec. and the camera's X-sync
speed.

If the flash has been fired 20 times continuously, allow the Speedlite to rest for 15
minutes to prevent the flash head from overheating. Overheating can cause the
flash head to breakdown.
