Power supply
The D2 unit can be connected to 100-120 VAC or 200-240 VAC,
50-60 Hz. The unit automatically senses and adapts to the voltage and
frequency supplied. The mains power supply fuse must not be smaller
than specified in the Technical data section.
Most gas generators with an output of 800 W constant load, or more,
can power the D2 unit. No Profoto ProGas unit is needed.
WARNING
Never use ordinary household extension cords to elongate the power cable. They may
overheat. Always unwind cord reel extension winders fully before use. Contact your
Profoto dealer for proper equipment.
Power on
1. Connect the included power cable to the power supply input [18]
and then to the AC mains supply. The power supply indicator [3] will
be red, indicating that the D2 unit is receiving power.
2. Push the ON button [4]. This will turn on the display [1] and turn
off the power supply indicator [3], indicating that the D2 unit is in
operational mode.
NOTE
By enabling a special setting, the D2 unit will be operational directly when the power
cable is connected. For more information, see page 16.
Power off
1. Push the ON button [4].
2. Remove the power cable.
When the D2 unit is switched off, the current settings are stored and will

Light output (energy level)
The light output of the flash light is shown on the display [1] in a relative
f-stop scale. The maximum energy (100%) is shown as 10.
The dial [5] is used to adjust the flash light output (energy level):
• Turn the dial clockwise to increase the output in 1/10 f-stop
increments and counter-clockwise to decrease.
