Set the MOD.LIGHT [13] control to continuous. The modelling lamp will automatically dim
down while recharging or when the energy output is changed. In this position the battery is
drained in 20 – 60 minutes depending on the lamp used (100 or 250 W) and the number of
flashes triggered.
Connecting Camera & Flash Meter
The two sync sockets [6] allow the camera and flash meter to be connected simultaneously.
The 5 m sync cord can be extended without limitations with sync extension cords. Further
sync connections can be made with the Profoto sync interconnection cable or by so called
"hard wiring". A slave signal from the photocell can be forwarded through this cable to
another flash generator.
The recharging starts when the ON/OFF switch [12] is pushed down. Slow or fast recharging
can be chosen. When the button FAST [10] is released, the generator will recharge slowly.
Push the FAST button [10] for normal fast recharging cycles; The recharging time is approx.
1.8 sec at full energy. When extremely short recharging times are required, for instance
when operating a motor-drive camera, choose lower energy settings. The lowest energy
setting offers the fastest recharging rate (0.04 sec or 25 flashes/sec.). The generator is
turned off by pressing down the button ON [12] for a minimum of three seconds.

The generator automatically turns off when the controls POWER [15,16], MOD.LIGHT [11]
and the sync outlets have not been in use for 30 minutes.
The built-in photocell [5] will sense flash release as well as IR-signals from most IR-trans-
mitters. The photocell is disabled when the button marked SLAVE [7] is released. The photo-
cell can also, via cable, trigger off an additional generator.
Signals, Audible & Visible
One of the indicator lights for the battery charge [3] will light up once the generator is
turned on. The charge indicator [3] is up-dated when the generator is turned on or when
a flash is fired. When all lights light up the generator has no charging value - fire a flash.
When the energy output is changed the white ready lamp [8] and the modelling lamp turns
off thus indicating that dumping or charging of the energy is in progress. A short "beep"
can be heard when the generator is fully recharged. Releasing the button SOUND [9] can
turn off this signal. The generator can be restarted directly from a camera, if a sync cord
is connected, by shooting a frame. If a flash is fired before the generator is fully charged
a long "beep" can be heard thus indicating an underexposed frame. A number of short
consecutive "beeps" can be heard before the generator automatically turns itself off.
