The mecablitz transmits different signals and messages to the camera when it is connected to the camera and is switched on.
4.1 Flash-ready indication
The orange light 
on the mecablitz illuminates when the flash capacitor is fully primed, thereby indi- cating flash readiness. This means that flash can be used for the next exposure. The flash readiness sig- nal is transmitted to the camera where it is indicated
kOn some cameras (depending on the 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. Please
refer to the camera’s operating instructions for further details.by a corresponding display in the camera’s viewfinder.
4.2 Automatic flash sync speed control
Most system cameras automatically change to flash sync speed when flash readiness is reached. The flash sync shutter speeds may vary between 1/30th and 1/250th second, depending on the camera model. Please refer to the camera’s operating instructions for further details.
