If you switch the flashgun on with the controls locked, the operating mode indi-

- set the operating mode selector to the operating mode which is blinking (if it is
not already there) and
- unlock switch
and lock it again.
Always carry out these two steps, since incorrect exposures may
otherwise result (depending on the operating mode).

Fig. 28: Switching on the beep function
The beep function can be used to indicate certain flashgun functions acoustical-
ly.An acoustic signal (beep) may be selected for the following situations:
• Flash readiness
• Correct exposure
• Incorrect operation (alarm)
An intermittent beep signalling alarm sounds:
• When, after loading a user program, the adjusted and stored operating modes
do not coincide.
• When, after calling a user program, a deviating ISO film speed is detected.
• When the flashgun is adjusted to auto mode,but the set values for aperture and
ISO film speed will exceed the light output control range.The aperture is auto-
matically adjusted to the next permissible f-stop.
• When the ISO film speed or the aperture are readjusted in the auto mode with
the result that the light output control range would be exceeded.
• When the camera transmits a focal length shorter than 24 mm.
• When the wide-angle diffuser is folded out, but the camera transmits a focal
length shorter than 20 mm.
• When the exposure is o.k. but flash readiness has not yet been reached.
