[. . . ] To mount the stand on the generator, lift the upper clamp on the stand fixture, then slip the stand through it and through the lower clamp as well. The stand will be locked in place when the upper clamp is released. G. 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. [. . . ] To change the angle of the lever, loosen the wing nut and move the lever to another groove in the panand-tilt device. If the lever locks too hard or too loose, adjust the wing nut. 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. To change the modelling lamp, you must first dismount the flashtubes. 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. The total modelling light wattage for the Pro-5 generator is 1500 W. IMPORTANT: Always disconnect the flash head plug from the generator before changing either modelling lamps or flashtubes. 12. THE FLASHTUBE minating manual adjustments. The mains power lamp shines green when the generator is AC connected. It is an "all voltage" generator, which can be connected to the most common voltages: 90-130 V, 180-240 V, 50-60 Hz. The generator is connected to the mains by a special cable and switches itself into the correct input voltage range, thereby eli- 15. IR-PHOTOCELL/SLAVE The IR-Photocell on the generator panel serves as a flash trigger. It can be activated by another flash, or by an IR-sync attached to the camera's synchronization mechanism. The photocell can be turned off by flipping the switch located beside it on the generator. When a sync cable is in use however, the photocell is automatically disabled. THE SYNC OUTLET The sync outlet is connected directly to the camera by a cable. 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. [. . . ] Depending on the current leakage of the capacitors, which can be high when the generator has not been used for a while, initial charging time can vary. In extreme cases, it can take up to several minutes, but normally it takes less than 60 seconds. This protects and reconditions the capacitors and will prolong their life expectancy. Once the flash unit has been turned on, it is possible to turn it off for a few minutes without it beginning to pulse charge again. [. . . ]
