Flash Output
The flash power output is variable over a four
f/stop range (five f/stops) from full power to 1/16
power in 1/10 f/stop increments. The power is
displayed on the LCD screen. Minimum setting is
2.0 and the maximum is 6.0. Pressing the up and
down touch-pad buttons under the LCD changes
the value by 0.1 f-stop (a total of 40 values). If the
current value is 5.6 and you want to reduce the
power by one stop, set the power to 4.6.
“Auto-Dump” Feature
While raising the flash power requires no
special consideration, lowering the power
does. Excess power that has built up in the
system’s capacitors must be released. The
VSD Monolight employs an “auto-dump“
or “auto-bleed” feature to accomplish this,
in order to avoid the necessity of manually
popping the flash after every adjustment.
When lowering the power, expect the flash
to automatically fire to release the excess
power.
Caution: To avoid eye damage, do not look into the strobe while firing. Do not fire the flash
in close proximity to the face. Turn the unit off when changing attachments.

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 the reflector. 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 source.
Locate the two flashtube pin sockets below 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, fasten the retention
spring over the hook above the flashtube. Re-insert the modeling lamp using white cotton
gloves or a clean cloth. Re-install the reflector.
