[. . . ] To mount the reflector, push it over the flash head and secure it in place. The reflector can be adjusted by referring to the numerical scale printed on the flash head and comparing it with the instructions for using the reflector. B. Slip the opening in the flash head pan-and-tilt device over the adapter, which is located on the end of the stand. Insert the lamp plug into the generator by matching the three white dots with each other, and secure it with the locking ring. C . [. . . ] If it is mounted sideways, it is possible to mount two lamp hooks (and flash heads) in the same pan-and-tilt device by turning the last disc section of the pan-and-tilt device 1/2 turn around. 8. THE LOCKING LEVER The locking lever works as a handle for manipulating the flash head. To change the angle of the lever, loosen the wing nut and move the lever to another groove in the panand-tilt device. For best results, the locking lever should be able to be turned around only with some difficulty. THE MODELLING LAMP On the back side of the flash head there is an attachment receptacle with a latching lever which connects the flash head to the lamp hook. The latching lever must be opened for mounting or dismounting, and it must always be closed when the flash head is mounted to prevent it from fallThe modelling lamp sits in the center of the flash head, mounted in a "mini-can" screw base. A 250 W modelling lamp is standard on the Pro-5 (500 W on the Twin flash heads). The maximum wattage of modelling lamp that can be connected to any one flash head 8 outlet is 1OOO W. IMPORTANT: Always disconnect the flash head plug from the generator before changing either modelling lamps or flashtubes. 12. THE FLASHTUBE minating manual adjustments. When the generator is connected to operating voltages other than those specified, the modelling light may vary somewhat from its nominal intensity. However, re-trimming can be performed by any workshop authorized to service Profoto products. When the cable is connected, the generator's photocell ceases to function. SOUND-CONTROL The generator has an audible signal system to indicate when the generator is charged. When this signal is undesirable, simply release the button marked "SOUND". SYNCHRONIZATION Synchronization of the unit is achieved either directly from the camera via a sync cable connected to the sync outlet, or by means of the built-in IR-photocell triggered by a flash, or through a signal from an IR-sync attached to the camera. The built-in photocell does not function when the sync cable is in use, but it can also be turned off manually. 22. FLASH HEAD CONNECTION When connecting the flash head plug, align the two white dots on the plug with the white dot on the generator panel next to the outlet. After connecting the plug, lock the connector into position by turning the locking ring on the plug clockwise. The plug is especially designed for flash use and can be connected or disconnected at any time before, during or after charging. Regarding All Models: In the symmetrical energy distribution mode (SYM), the flash heads can be connected to any of the outlets. The designated energy is divided EVENLY between the connected flash heads, regardless of which outlet they are connected to. Thus, ONE flash head connected will receive 100% of the energy; TWO flash heads will receive 50% of the energy each; THREE flash heads will each receive 33. 3 %. [. . . ] The difference can be as great as from 0. 2 seconds (Pro-5/1200 at 1/8 intensity) to approx. 6 seconds (Pro-5/4800 at 1/1), based upon a normal mains supply voltages. Charging time can be decelerated by releasing the FAST button on the generator panel. This slower charging time is useful when mains energy is weak, since it does not allow the unit to tax the mains fuses unnecessarily. [. . . ]
