Power Supply
Plug the power cord into the back of the ash unit. Before plugging the power cord into
the wall socket, make certain that the power switch is set to the OFF (circle) position. The
VSD is designed to automatically ash, if necessary, when turned off. The resistive dump
will continue to reduce any remaining energy while the unit is off. This is a safety feature
and cannot be disabled.
Note: The VSD flash unit is designed to work on 110-120V 50/60Hz AC current.
Power Switch
Turn the power switch to the ON (line) position. The flash will
sound a beep and the LCD will show the current ash power
setting. We recommend charging the flash unit for one hour
prior to its initial use and after an extended period of inactivity
(more than two weeks). If the unit is left unused for a few
months, or the unit has been used predominantly at low power
settings, we recommend that the power be increased to the
maximum and the unit left switched on (with the modeling lamp
OFF) for at least 30 minutes, to help preserve the life of the
capacitors.

Changing the Fuse
A 6A 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. A spare 6A fuse is tted within the fuse holder. Use a
small screwdriver to release the fuse cover. Remove the old fuse, place the new fuse in
the slot, then replace the fuse holder.
