[. . . ] Do not expose batteries to excessive heat, sunshine, fire and the like!Exhausted batteries should be immediately removed from the flash unit!Do not expose the flash unit or battery charger to dripping or splashing water (such as rain)!Never place material that is impervious to light in front of, or directly on, the reflector screen. [. . . ] F/5, 6 instead of f/2, 8) on the flash and the camera, or reduce the distance to the subject or the reflecting surface (e. " correct exposure confirmation briefly lights up on the flash when the picture was correctly exposed in the auto flash mode. On the flash can be used in the auto flash mode to establish prior to shooting whether or not the flash will be sufficient for the selected auto working aperture. When firing a test flash point the flash unit in the same direction as for the subsequent shot. Select on the camera the "Manual Mode M" with aperture and shutter speed priority or the automatic "Aperture Priority Mode" ("A" or "Av") (see operating instructions for the given camera). When in "Manual Mode M" set the flash sync speed on the camera (e. In the "Aperture Priority Mode" ensure that the camera does not select a shutter speed faster than its flash sync speed!Should this be the case, set on the lens a higher f-number (= smaller aperture opening)!When in automatic flash mode the sensor integrated in the flash measures the light reflected from the subject. The flash unit automatically cuts off the flash as soon as the amount of light required for correct exposure has been reached. In this manner the aperture does not have to be recalculated and reset when the distance changes, provided that the subject remains within the auto flash range indicated on the aperture calculator. The sensor must be pointing at the subject irrespective of the reflector setting. Two colour-coded auto working apertures (green ­ red) are available, depending on the given ISO film speed. The auto working aperture is selected with the main switch (green red) on the flash and depends on the camerato-subject distance. On the aperture calculator at the rear of the flash unit, you can read off the f-stop at the right, the ISO sensitivity at the left, and, above, 6 m A minimum distance to the subject should be maintained to avoid overexposure. The middle third of the zone between the minimum distance and the maximum flash range to give the electronic circuit sufficient leeway for light control. You choose the f/2, 8 "green" auto-working aperture (maximum flash range given by the aperture calculator: approx. 2 Manual flash mode , , M" The flash always fires uncontrolled flashes at full light output when in manual mode. Their design they can cause a loss of light of as much as one aperture increment. They may also have different effective aperture values for the different focal length settings. This will then have to be compensated by manual correction of the aperture setting on the flash unit!1 Manual flash mode with a given aperture · The flash unit's aperture calculator indicates in metres (m) or feet (ft) the camera-to-subject distance required for the individual fstop. [. . . ] The following rule of thumb will help you determine the maximum flash range for a room of normal height: Guide number Maximum flash range = ­­­­­­­­­­­­­­­­­­­­­­­­­ (flash-to-subject distance x 2) Remove any grime and dust with a soft, dry or silicon-treated cloth. Forming the flash capacitor The flash capacitor incorporated in the flash unit undergoes a physical change when the flash unit is not switched on for prolonged periods of time. The batteries must supply sufficient power for flash readiness to be indicated within 1 minute after the flash was switched on. 5500 K Film speed: ISO 25 to ISO 400 Auto apertures: f/2, 8 - f/5, 6 with ISO 100 Synchronisation: Low-voltage ignition Number of flashes (at full light output): approx.
