Power Supply
Plug the power cord into the back of the ash unit . Before plugging the power cord into
the wall socket, make cer tain that the power switch is se t to the OF F (circle) position. T he
VSD is designed to automatically ash, if necessary, when turned off. The resistive dump
will continue to reduce any remaining energy while the uni t is off. T his is a safety feature
and cannot be disabled.
Note: The VSD flash unit is designed to work on 110-120V 50/6 0Hz AC current.
Power Switch
Turn the power s witch to the ON (line) position. The flash will
sound a beep and t he LCD will show the current ash power
set ting. We recommend charging the flash unit for one hour
prior to it s initial use and af ter an extended period of inactivi ty
(more t han t wo weeks). If the unit is left unused f or a few
mont hs, or the unit has been used predominantly at low power
set tings, we recommend that the power be increased t o the
maximum and the unit le ft switched on (w ith the modeling lamp
OFF) for at least 3 0 minutes, to help preser ve the lif e of the
capacitors.
