TEST Button
There are three ways to trigger your flash, but the simplest is to press the red TEST
button. This is useful when you need to discharge the power built up in the flash unit,
for example, just before replacing the flashtube (more on that later).
Sync Connection
The sync jack on the EX-100A Monolight may be used for
direct connection to a camera set to ‘X’ synchronization.
Insert the “PC” end of the supplied sync cord into the
connection on your camera and the other mini-plug end
into the sync jack on the back panel of the EX-100A.
A radio slave receiver with a mini-plug may also be
plugged into this jack.
Photo Cell
The EX-100A Monolight features a photo cell which
allows the flash unit to be triggered by another flash.
This is called “Slave Mode.” The photo cell is located on
the back panel next to the ready light. The photo cell is
very sensitive, but some experimentation with
positioning may be necessary to ensure a reliable trigger,
particularly if the cell is not in the direct line of sight of
the triggering flash unit. Avoid directly illuminating the
photo cell from a continuous light source (such as ceiling
lights or windows) since this can prevent correct
operation. Very high ceilings can also affect the
operation of the photo cell.
The EX-100A is always in Slave Mode, even when using
sync cords. To disable the photo cell, cover both the
ready and photo cell sensors with black electrical tape.

Breaking Down Your Softbox
Turn off the power to your light head and
disconnect the power supply. Unmount the
softbox assembly from the monolight. Remove both diffusers. Release a flex rod
by folding the corner of the softbox away
from its captured rod.
The second rod to be released should be
the one opposite the first. Continue with
the third and fourth flex rods. Pull the flex rods from the mounting ring.
Stow everything until the next shoot.
