[. . . ] This will protect the flashgun against overload. NEVER place material that is impervious to light in front of, or directly on, the reflector screen. The reflector screen must be perfectly clean when a flash is fired. The high energy of the flash light will burn the material or damage the screen if this is not observed! [. . . ] Please refer to the camera's operating instructions to find out whether your camera features this function. A full-power flash is fired if the camera does not feature TTL flash control! in other words: Without TTL flash control , the mecablitz fires an unmeasured flash at maximum output. If there is a flashgun integrated in the camera it must be switched off or completely folded down when the mecablitz is used. 2 Switching the flashgun on and off Set the main switch in the ON position to turn on the flashgun. The green flash-ready indicator lights up to indicate flash readiness. The mecablitz transmits different signals and messages to the camera when it is connected to the camera and is switched on. 1 Flash-ready indication The green light on the mecablitz illuminates when the flash capacitor is fully primed, thereby indicating flash readiness. This means that flash can be used for the next exposure. the flash readiness signal is transmitted to the camera where it is indicated by a corresponding display in the camera's viewfinder. On some cameras (depending on the model) the shutter is automatically changed to flash sync speed when flash readiness is reached. Flash shots at low lighting levels and fast shutter speeds (normal flash sync speed) can often result in overexposed subjects in front of a very dark back-ground. The slow-sync function allows the use of slow shutter speeds right up to 30 seconds, to significantly enhance the background as a result of the extra ambient light. This makes the light trail behind the moving objects instead of appearing in front of them, and renders a more natural looking picture. With normal synchronisation, the flash is fired precisely after the opening of the first shutter curtain. When using slow shutter speeds, and with moving objects, this would result in an unnatural rendition of light traces. With second curtain or rear curtain synchronisation, the flash is fired as the exposure is ending, just before the second curtain covers the film again. Auto program mode with flash (P-function) In this mode, the camera automatically activates the flash function when the ambient light level is too low, it automatically adjusts the aperture and shutter speed, and triggers the flash when the shutter release is pressed. the flashgun is not triggered in the creative program modes PA/PS!Triggering control On some cameras the flash will not be fired when the prevailing light is sufficient for an exposure in normal mode. The exposure is then completed with the settings indicated in the display field. please refer to the camera's operating instructions for further details. [. . . ] To remove turn the attachment beyond the retaining spring (see fig. Remove grime and dust with a soft, dry cloth. Do not use cleaning agents as these could damage the plastic parts. Forming the flash capacitor The flash capacitor incorporated in the flashgun undergoes a physical change when the flashgun is not switched on for prolonged periods. [. . . ]
