Signals, Visible & Audible
The green indicator [3] below the handle will light up when the generator is connected to the
mains supply. The white ready lamp button [11] will light up when the generator is fully charged.
The characteristics of the light vary (please see ”Autobracketing” page 20). When the generator
is fully charged a short ”beep” can be heard. Releasing the button [12] marked SOUND can
turn off this signal. The red indicator [16] will light up and the ”beep” will sound if the energy
dial A [5] is in the A ONLY area and the dial B is not pointed towards the red indicator. Point dial
B towards the red indicator and the ”beep” will disappear.
If a flash is released before the generator is fully charged a long ”beep” will sound, indicating
an underexposed frame.
Reliability Testing - The R-Test
The Profoto R-test guarantees that all products leaving the factory meet the very high stan-
dards required of professional equipment by professional photographers. The R-test is a rigor-
ous performance test that Profoto generators are put through - 720 full power flashes are
released during one hour, which is equivalent to 20 rolls of 35 mm film. After the test the
equipment is examined to see that all parts have kept a normal operating temperature and are
not malfunctioning in any way. All Profoto products are subjected to the R-test prior to being
shipped.
