Power supply
The Pro-8a generator can be connected to 100–120 VAC or 200–240 VAC,
50–60 Hz. The power supply fuse must not be smaller than specifi ed in

ARNING
:
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.
Due to the two stage SMPS (Switch Mode Power Supply) technology,
the Pro-8a could make a hearable sound during the recharge cycle. This
is fully normal and could be seen as the sign of power being charged into
the generator.
Energy control
The selected energy levels for channel A and B are shown in Flash Light
Energy Display A [6] and B [17].
The f-stop scale reading is default. To show energy in Ws scale, push and
