User manual PROFOTO ACUTE2 HEAD

[. . . ] Acute2 manual Profoto, Stockholm, Sweden. Warning Profoto generators and lamp heads are parts of a complete professional lighting system. Flash tubes and modelling lamps emit considerable heat and may cause injury if not handled properly. Note, always unplug the lamp cable from the generator before changing the modelling lamp or flash tube. · Under no circumstances are generators or heads to be opened. High voltage is inside the equipment. [. . . ] This means 4 flashes a minute at 2400 Ws, 8 flashes at 1200 Ws, 16 flashes at 600 Ws, etc. Changing flash tube is only to be done at a professional service station. Mounting the reflector: ·Remove the two ridged screws fixating the camera holder. ·Remove the four ridged nuts holding the outer and inner reflectors together. ·Run the lamp cable through the outer reflector and let the reflector slide into position. ·Reassemble the outer and inner reflectors using the ridged nuts. ·Reassemble the camera holder using the two ridged screws. 10 06 42 Softlight Reflector Ring 10 06 43 Close-Up Reflector Ring 13 Nomenclature 1.

Reduce the energy one f-stop by switching A+B / A<- >B switch to position A<- >B. Further reduce the energy one or two f-stops by halving or quartering the energy with the A-switch. Use the dial BRACKET for fine adjustments and to further reduce the energy by two f-stops. Reduce the energy one f-stop by switching A+B / A< -> B switch to position A<- >B. Further reduce the energy one or two f-stops by halving or quartering the energy with the B-switch. Use the dial BRACKET for fine adjustments and to further reduce the energy by two f-stops. Connect one head to the A socket and one head to one of the B sockets. Reduce the energy one or two f-stops by halving or quartering the energy with the A-switch for the head connected to the A-socket. 18 4. Use the dial BRACKET for fine adjustments and to further reduce the energy by two f-stops. The energy for the two groups is now added and then equally divided between the connected heads. Use the dial BRACKET for fine adjustments and to further reduce the energy by two f-stops. Reduce the energy for the head connected to socket A by one or two f-stops by halving or quartering the energy with the A-switch. Reduce the energy for the heads connected to sockets B by one or two f-stops by halving or quartering the energy with the B-switch. [. . . ] The protection functions are automatically reset when the temperature is lowered. Protection from wrongly set mains voltage selector switch inhibits charging for 5 seconds and shuts off if wrongly set. For quality reasons, the first charging cycle is longer than the following.
