• The flash may fire if another flash is being used in close
proximity.
• The High-Power Flash may not fire outdoors in daylight or
when there are no reflective items.
• For continuous shooting, although the flash fires for the first
shot, it does not fire for subsequent shots.
• Fasten the attachment screws securely so that they do not
loosen. Failure to do so may lead to the dropping of the
camera and flash resulting in damage to both.
• Before attaching the bracket to the flash, check that the
lithium battery (CR123A or DL123) is installed.
• To illuminate the subjects properly, install the flash so that it
is up against the side of the camera and parallel with the
camera's front panel.
• A tripod can be used even when the flash is attached.
Batteries
• Charge becomes Severely Limited
If the battery usage time has considerably diminished, wipe the battery
terminals well with a dry cloth. The terminals may be dirty from
fingerprints.
• Usage in Cold Temperatures
Get a spare generic lithium battery (CR123A or DL123). You are
recommended to place the spare battery in your pocket to warm it up
before switching it for the battery in the flash.
• Non-Use over Extended Periods
Leaving batteries in the High-Power Flash could allow the battery fluid
to leak, damaging the product. Remove the batteries from the High-
Power Flash and store them in a cool, dry place.
