3. Setting the mecablitz into operation

3.1 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 (see
also page 34). Please refer to the camera’s ope-
rating 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 meca-
blitz 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.
3.2 Switching the flashgun on and off, film
speed
ON/OFF switching: Turn on the mecablitz with the
I switch. The green operating light will light up. The
orange flash ready light illuminates when flash
readiness is reached. Press the 0 switch to turn off
the flashgun. The green and orange lights are
instantly switched off. No flash will be fired for the
next shot if the mecablitz remains in this state on the
camera.
Setting the film speed on the mecablitz: Adjust the
speed of the film loaded in the camera on the back of
the flashgun by selecting the required value in the
„ISO Window“ with the aperture slide.
