[. . . ] Chemicals leaking out of spent batteries will damage the flashgun. Batteries should not be exposed to excessive heat, for instance sunshine, fire and the like!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. [. . . ] 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 operating mode and camera model) the shutter is automatically changed to flash sync speed when flash readiness is reached. The flash will not be fired if the shutter is released before the flash ready light illuminates with the result that the exposure may be incorrect if the camera control circuit has already changed over to flash sync speed. 2 Automatic flash sync speed control When the flash unit is on, the camera will automatically switch it to flash sync speed from any operating mode selected. The sync speed depends on the camera model and usually ranges between 1/30 sec. Some camera models will, when the flash unit is on, switch it to flash sync speed as soon as program mode , , P" or full-auto mode is selected. Speeds faster than the flash sync speed cannot be set. 4) The red correct exposure light briefly illuminates when flash exposure was correct. 4 Information displayed in the camera's viewer The following table only gives a general survey. camera-specific deviations ar possible (please refer to the camera's operating instructions. Blinks: Indicates that flashgun should be used or switched on (on some cameras). The flash is ready for use (on some cameras) Please refer to your camera's operating instructions to find out if this applies to your camera model. The mecablitz receives its information exclusively from the connected TTL-controlled camera. exposure measurement in TTL mode (TTL = through-the-lens) is completed by the camera's sensor. This sensor measures the light reaching the film through the camera lens. An electronic control circuit within the camera transmits a stop signal to the flashgun as soon as the film has been exposed by the correct amount of light; the flash is then instantly cut out. The advantage of the TTL mode is that all factors influencing the exposure of the film (such as filters, change of aperture or variable aperture zooms) are taken into account. You need not worry about adjustment of the light output. Spot , matrix or centre-weighted overall readings) offered by some cameras.  If the actual distance is shorter than the Minimum lighting distance, then this may result in overexposure. A strip of film must be loaded in the camera if tests are to be conducted in TTL flash mode. The effective flash range can only be checked by the correct-exposure display (o. [. . . ] 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. [. . . ]
