[. . . ] 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 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. Depending on the selected operating mode, the camera is 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 Flash readiness has the following effect on system cameras: Effect: Camera mode: Programmed auto exposure mode [P]: Camera changes to 1/30 - 1/250 sec. flash sync speed , depending on camera model. As in [P] Aperture priority mode[Av]: Shutter priority mode [Tv]: Shutter speeds can be set on the camera that equal or are slower than the sync speed. Manual mode [M]: As in [Tv] Note: If (independent of the operating mode) a shutter speed faster than the flash sync speed is set on the camera, the camera will automatically change to flash sync speed when flash readiness is reached. 4 Information displayed in camera viewfinder when flash unit is switched on Displays in viewfinder Meaning prior to shutter release not illuminated Flash unit not yetready for firing or blinks slowly permanently illuminated Flash unit is ready for firing Warning with SF1/SFx: is illuminated in the camera's viewfinder but the flash is not triggered when the shutter is tripped. The camera has activated the triggering lock because the ambient light is too bright. Displays in viewfinder Meaning prior to shutter release blinks quickly Flash was sufficient for correct exposure not illuminated or Flash was insufficient. 4) The red correct exposure light briefly illuminates when flash exposure was correct. The mecablitz receives its information exclusively from the connected TTL-controlled AF-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 centreweighted overall readings) offered by some cameras. [. . . ] For this reason it is necessary to switch on the flashgun for approx. 10 minutes every 3 months and to fire a few flashes The batteries must supply sufficient power to light up the flash-ready light within one minute after the flashgun was switched on. Manual firing button An uncontrolled flash can be fired with the manual firing button (see fig. 8: Manually firing button Troubleshooting: If the flashgun does not work as it should in the individual modes, then proceed as follows: · Switch off the flashgun with the main switch.
