Flash Duration
In order to reduce the flash duration use first the SYM/ASYM switch (2) and the position of
the head before using the POWER dials (15,16)
(For more details please see ”Energy control” on page 22 and ”Technical Data” on page 28).
Lamp Heads
The ProHead, ProTwin, Pro-7 head, the Pro-7 twin, the Pro-7 ring or the exclusively designed-
Pro-B orPro-7b head can be used. With the ProTwin and two Pro-7b generators 2400 Ws
can be obtained. When using the new ProHead or ProTwin heads the fan will work when
connected to the Pro-B2.
Radio receiver (optional)
The optional built-in radio receiver is available in 433Mhz (CE version) or 344Mhz (US).
They are compatible with all PocketWizard Plus transmitters and PocketWizard MultiMAX
transceivers working on the same frequency! Please make sure to use the frequency allowed
in your country.
The radio receiver has 32 different channels and the last 16 have also 4 sub channels (zones),
which can be used for triggering only the background light, ceiling light etc.
There is a special dial (14) for setting the first 4 radio channels and a special learn mode to set
the other 28 channels.
To set the channels 5 – 32 set the Radio control (14) to learn, turn off the generator and turn it
back on again and within 30 seconds trigger a flash by pushing and holding down the trigger
button on the PocketWizard until the flash triggers (3-5 seconds). The receiver is now set to
the same channel as selected on the Pocket Wizard Transmitter. If you want to change the
channel, first select the desired channel on the transmitter and repeat the above procedure.
The generator will remember the selected channel in learn mode but next time you turn on
the Pro-B2 it takes approx. 30 seconds before you can trigger a flash.

Safety Functions
If the generator for any reason whatsoever overheats, the recharging will completely stop.
After a while, when the temperature has gone down sufficiently, the generator will start
recharging at a normal pace again. No recharging can take place when the red light of the
battery indicator [3] is on.
This is a safety feature protecting the battery from harmfully low discharging. There are
three fuses on the battery cassette. One is for the charging circuits and two for the battery.
Furthermore the contacts are short-circuit proof.
PLEASE NOTE: Never store your flash equipment in a car on a hot and sunny day. Avoid
storing the generator close or below the freezing point, which can lead to loss of capacity
(flash output) and risk of condensation when used in a warmer surrounding immediately.
Do not expose any flash equipment to wet or humid environments or extreme electro-
magnetic fields.
Reliability Testing - The R-Test
The Profoto R-test guarantees that all products leaving the factory meet the very high
standards required of professional equipment by professional photographers. The R-test
is a rigorous performance test that Profoto generators are put through - 360 full power
flashes are released during one hour, which is equivalent to 10 rolls of 35 mm film. After the
test the equipment is examined to see that all parts have kept a normal operating tempera-
ture and are not malfunctioning in any way. All Profoto products are subjected to the R-test
prior to being shipped.
Colour Temperature
The Pro-7 generators are perfectly suited for critical analogue (film) and digital shoots.
The colour temperature is constant with a variation of a maximum of +/- 150°Kelvin.
PLEASE NOTE: combining flash tubes and/or glass covers with different coatings can make
even more distinctive colour temperature adjustments.
