[. . . ] Protect the flashgun against excessive heat and high humidity levels!In the event of flash shots with full light output observe an interval of at least 3 minutes after a series of 20 flashes. This will protect the flashgun against overload. NEVER place material that is impervious to light in front of, or directly on, the reflector screen. [. . . ] Press the unlocking catch at the back of the mecablitz (fig. 1 Preconditions The mecablitz must only be used with TTL flash controlled cameras!The sensor of TTL flash controlled cameras measures the light reaching the film through the camera lens and instantly cuts out the flash when the film has been correctly exposed. 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. With normal synchronisation, switching to the camera's flash sync shutter speed is automatic. The shutter speed may vary from 1/30th and 1/300th seconds, depending on the camera model. 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. Use of flash in the program modes TTL-controlled flash shots can be made in all exposure and auto program modes. Once the mecablitz is attached to the camera and switched on, it automatically operates with TTL flash control in auto program (P), aperture priority (A), shutter priority (S) and manual (M) modes. for details please refer to the camera's operating instructions. [. . . ] Turn the attachment clockwise and insert the guiding edge into the case gap. 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. [. . . ]
