User Manual

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 ash 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 ash 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 ash 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.
