The Modeling Light switch is to the right of the
power switch and has three settings: Proportional
Mode, Full Power, and Off.
Proportional Mode
During normal use, most photographers will use a
monolight in “Proportional” Mode. The modeling
light intensity will increase or decrease in response
to changes in the flash power. To work in
Proportional Mode, rock the modeling light switch so
that bottom of the switch (marked with double
horizontal lines) is down.
Full Power
The EX-100A allows you to reduce the flash power
but keep your modeling light at full power. Rock the
modeling light switch so that the top of the switch
(marked with a single horizontal line) is down. The
modeling light will stay on at its full power.
Off
To turn off the modeling light, set the modeling light
switch to its middle position (marked with an “O”).

Changing the Flashtube
Discharge the Flash Unit
The charge in the flash unit must be discharged before removing the flashtube. Make
sure the flash unit is on. Push the TEST button on the rear panel of the flash. The unit will
flash, discharging the power. Immediately turn off the power switch on the rear panel.
Unplug the power cord from the power source. It is advisable to wait at least 30 minutes
before touching or removing the flashtube.
Remove Old Flashtube
First, remove any reflector, softbox, or flash head accessory. Then, using white cotton
gloves or a clean cloth, remove the modeling lamp. You will need to remove the retention
spring wrapped around the top of the flashtube. With needle-nose pliers, unhook the
retention spring loop. Using white cotton gloves or a clean cloth, grip the base of the
flashtube on each side. Carefully pull the flashtube from the flash unit.
Install New Flashtube
Make sure the power switch is off and the power cord is disconnected from the outlet.
Locate the two flashtube pin sockets above the modeling lamp socket. Using white
cotton gloves or a clean cloth, push the pins of the flashtube into the sockets using firm,
even pressure at the base of the flashtube. With needle-nose pliers, hook the retention
spring over the hook above the flashtube. Reinsert the modeling lamp using white cotton
gloves or a clean cloth. Reinstall the reflector.
