Power Supply
Plug the power cord into the back of the flash unit. Before plugging the power cord into
the wall socket, make certain that the power switch is set to the OFF (circle) position.
Note: The EX-100A flash unit comes in two designs; one is designed for use with 110/120V
AC power in the US and the other for use with 220V AC power in Europe. Neither model can
be used outside of its native power region.
Power Switch
Turn the power switch to the ON (line) position.
The flash will sound a beep and then sound a
second beep indicating that flash power has been
reached and the unit is ready to fire. The green
ready light will also be lit. We recommend
charging the flash unit for one hour prior to its
initial use and after an extended period of
inactivity (more than two weeks). If the unit is left
unused for a few months, or the unit has been
used predominantly at low power settings, we
recommend that the power be increased to the
maximum and the unit left switched on (with the
modeling lamp OFF) for at least 30 minutes, with
several test flashes fired, to help preserve the life
of the capacitors.

Safety and Maintenance Notes
Safety Notes
• Do not use your flash in an environment where moisture
may come in contact with the unit.
• A fire hazard exists if flammable materials are placed in close proximity
to the flashtube or the modeling lamp. Do not use your flash
in an environment where flammable vapors are present.
• Do not restrict the ventilation holes when the flash is in use.
• Always switch off the power and disconnect the power cord
before changing the fuse, modeling lamp, or flashtube.
• Avoid placing cables where they can be tripped over.
Replace damaged cords immediately.
• Never use a flash unit with damaged covers, moldings, flashtube,
or modeling lamp. If the unit is dropped or damaged,
have it checked by a professional repair service before using.
• Due to the high-voltage circuitry inside this device,
do not attempt to disassemble or repair the unit yourself.
• Keep out of the reach of children.
Maintenance Notes
• Turn the power off and unplug the power cord when the flash is not in use.
• We recommend charging the flash unit for one to two hours prior to its initial use
and after an extended period of inactivity (more than two weeks).
• If the unit is left unused for a few months, or the unit has been used predominantly
at low power settings, we recommend that the power be increased
to the maximum and the unit left switched on (with the modeling lamp OFF)
occasionally for at least 30 minutes to help preserve the life of the capacitors.
• Avoid rapid, high-power flashing, especially when using restrictive reflectors
such as snoots or grids. Excessive heat will shorten the lifespan of your flash unit,
modeling lamp, and flashtube.
