impact VSD-160 - Proportional Mode

7
There are three modes for the modeling light:
Proportional, Full, and Off. You can choose a mode by
pressing the modeling lamp control button, which is
to the left of the FULL and PROP LEDs. Each time you
press, the mode will change.
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. In this mode, the PROP
LED will be lit and adjustments to the ash power
buttons will also adjust the power to the modeling
lamp proportionally.
Full Mode
The VSD allows you to set the ash and modeling
light to different intensities. You may wish to reduce
the intensity of the modeling lamp but keep the ash
power where it is. Depress the up or down modeling
lamp buttons to the desired level on the digital
readout (2.0 to 6.0). When you are nished adjusting
the modeling light, the digital readout will blink four
times before returning to display ash power. The
FULL status LED will be lit during this mode.
Off
To turn off the modeling light, depress the modeling
light button until the lamp is extinguished. The PROP
and FULL status LEDs will be off.

Umbrellas
An umbrella with a shaft diameter of up to 8mm can be secured in the umbrella holder.
Firmly press the umbrella shaft through the holder. The locking knob is located beneath
the holder. Do not overtighten to avoid damaging the shaft of the umbrella.
The monolight can be
pointed up or down by
loosening the release lever.
Adjust to your preferred
angle and then tighten the
lever back down.
Use of Umbrellas and Softboxes
Softboxes
The VSD Monolight accepts softboxes with a Bowen mount-design speed ring. Install the
softbox the same way you install reectors. Match up the three tabs at the back of the
softbox speed ring with the three slots on the ash head. Press in and turn clockwise
until the softbox locks in place.
