Note: For the FEB mode, set the camera's drive mode to single shooting and be sure the
flash is ready before shooting.

28
Auto Zoom for Image Size (Canon)
EOS DIGITAL cameras have one of three image sizes. The lens’ effective focal
length will differ depending on the camera’s image size. The flash automatically
recognizes the EOS DIGITAL camera’s image size and automatically sets the flash
coverage for lens focal lengths from 24mm to 105mm. When the flash is attached to a
compatible camera, < > will appear on the flash’s LCD panel.

TROUBLESHOOTING
The flash does not fire.
1. The batteries are installed in the wrong orientation. Install the batteries in the
correct orientation.
2. The flash’s batteries are exhausted: If the flash recycling time takes 30 seconds or
longer, replace the batteries.
3. The flash is not attached securely to the camera. Attach the flash’s mounting foot
securely to the camera.
4. The electrical contacts of the flash and camera are dirty. Clean the contacts.
The slave unit does not fire.
1. The slave's wireless mode is not set to <SLAVE>. Set it to <SLAVE>.
2. The slave unit(s) is not positioned properly. Place the slave unit within the master
unit's transmission range. Point the slave unit’s sensor toward the master unit.
The power turns off by itself.
1. Auto power off (sleep) is in effect. Press the shutter button halfway or press the
test fire button.

32
The edges or bottom of the picture looks dark.
1. When you set the flash coverage manually, the setting has a higher number than the
lens focal length, resulting in dark edges. Set the flash coverage that is a lower
number than the lens focal length or set it to auto zoom.
2. If only the bottom of the picture looks dark, you were too close to the subject. If the
subject is closer than 2 m/6.6 ft., tilt the flash head downward by 7° (bounce flash).
The flash exposure is underexposed or overexposed.
1. There was a highly reflective object (glass window, etc.) in the picture. Use FE lock.
2. The subject looks very dark or very bright. Set flash exposure compensation. For a
dark subject, set a decreased flash exposure. And for a bright subject, set an
increased flash exposure.
IMPORTANT INFORMATION
• Do not fire flashes from a short distance directly into the eyes of people or animals.
This can cause damage to the retina and may even lead to blindness.
• Always use batteries of the same type, brand, and age. Always replace all 4
batteries at the same time. Do not combine different types, brands, old, or new
batteries. This could cause the batteries to overheat, leak, or explode.

33
• While Ni-MH or Lithium AA batteries may be used in your flash, using AA
batteries other than alkaline type may cause improper battery contact due to the
irregular shape of the battery contacts.
• Install the batteries in proper orientation as indicated in the battery chamber.
Installing the batteries incorrectly could cause the batteries to overheat, leak, or
explode.
• If you change the batteries after a period of sustained continuous firing of the
flash, the batteries may become warm or hot. This is normal, however you should
take care when handling the batteries.
• Always switch off the flash before changing the batteries.
• Do not attempt to open the flash because the electronic circuit contains high
voltage.
• If the flashgun is badly damaged and internal components are exposed, remove
the batteries from the flash. Contact customer service. Never try to repair the
flashgun by yourself.
• This product is not water-resistant. Keep it away from rain, snow, and high
humidity areas.

34
• Do not clean the flash with agents containing corrosive or flammable substances.
Also, do not store or use the flash in flammable conditions.
• To avoid overheating and degrading the flash tube, do not fire more than 20
continuous flashes in rapid sequence. After 20 continuous flashes, allow a rest
period of at least 10 minutes. If you fire more than 20 continuous flashes in rapid
sequence and then fire more flashes in short intervals, the internal overheating
prevention function may be activated and the recycling time will increase to about
8 to 20 seconds. If this occurs, allow a rest time of about 15 minutes and the flash
recycling time will return to normal..
• If you use a commercially available sync cord to connect the camera to the flash
PC terminal, be sure to set the flash zoom manually for proper coverage.
• In the Multi Mode (stroboscopic flash), the camera’s shutter should remain open
until the flash completes the number of flashes that have been set. The shutter
speed to set on the camera is calculated by Number of flashes ÷ Firing frequency
= Shutter speed. For example, if the number of flashes is 10 and the firing
frequency is 5 Hz, the shutter speed should be at least 2 seconds.
