User manual PROFOTO PRO-81

[. . . ] Under no circumstances are generators or heads to be opened!Do not connect the lamp head with the transport cap in place. Never place filters or diffusing material directly onto glass covers, flash tubes or modelling lights. Never position the light extremely close to people. [. . . ] 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. 22 [11] Colour Temperature [12] [16] The colour temperature is constant and reliable regardless of the energy output chosen with the dials A, B1 & B2. The colour temperature can be adjusted with the MASTER control [6]. Each 1/6 increment reduces the colour temperature by 50° Kelvin, which means a total downscale of 400° Kelvin. PLEASE NOTE: combining flash tubes and/or glass covers with different coatings can make even more distinctive colour temperature adjustments. Flash Duration The flash duration can be shortened by reducing the energy output with the dials A and B. The shortest flash duration using a Pro-7 head and a Pro-7a/1200 generator at 1/16 energy is 1/12000 sec. PLEASE NOTE: Reducing the energy output with the MASTER control [6] will not affect the flash duration. (For more details please see "Technical Data" on page 24). Lamp Heads The following are suited for Pro-7a 1200/2400: Pro-7 head Pro-7b head Pro-7 ring Warranty All Profoto products are guaranteed for a period of two years with the exception of flash tubes, glass covers and modelling lamps.

Mains Connection connected to all common mains voltages 90-240V and 50-60Hz. The generator automatically senses which voltage range is supplied. The green lamp below the handle indicates that the generator is receiving power from the mains. (Please also see "Gas Generator" on page 32). Warning: Never use ordinary household extension cords to elongate the power cable. Pro-7s 1200/2400 Use the included power cable to connect to the mains power supply. The generator can be 27 [2] Connecting Lamp Heads [4] [5] One or two lamp heads can be connected to the lamps head sockets [2]. When connecting the lamp head plug, align the dots on the plug with the white dot on the generator panel. [. . . ] 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. [. . . ]
