Power Cord
Before plugging the power cord into the wall socket, make certain that the power switch
is set to the OFF (“O” position). Note: The VS-LCD flash unit is designed to work on
110-120V 60Hz AC current.
Power Switch
Turn the power switch to the ON (“—“)
position. As the power is turned on, the
internal cooling fan will immediately begin
to operate. The unit will give an audible
beep and display the voltage on the LCD
screen for a moment. The flash is fully
prepared to operate with a second audible
beep and the LCD screen showing all operations and controls.
Changing the Fuse
A 10A fuse is mounted in the rear panel and protects the circuitry of the flash unit. Turn
off the unit and disconnect the power supply before changing the fuse. Never replace
with a fuse of a different type or rating. Use a small screwdriver to release the fuse
cover. Press in and turn counter-clockwise. Place the new fuse in the cover, insert into
the flash unit, then lock the cover by pressing in and turning clockwise.

Discharge the Flash Unit
The charge in the flash unit must be discharged before removing the flash tube. 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 flash tube.
Remove Old Flash Tube
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 flash tube. With needle-nose pliers, unhook the retention spring loop. Using white
cotton gloves or a clean cloth, grip the base of the flash tube on each side. Carefully pull
the flash tube from the flash unit.
Install New Flash Tube
Make sure the power switch is off and the power cord is disconnected from the source.
Locate the two flash tube pin receptacles above the modeling lamp receptacle. Using
white cotton gloves or a clean cloth, push the pins of the flash tube into the receptacles
using firm, even pressure at the base of the flash tube. With needle-nose pliers, hook the
retention spring over the hook above the flash tube. Re-insert the modeling lamp using
white cotton gloves or a clean cloth. Re-install the reflector.
