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.
