13 Triggering control (auto-flash)

The camera prevents the triggering of a flash if the ambient light level is suffi-
cient for an exposure in the normal mode. The exposure is then completed with
the shutter speed given in the display or viewfinder of the camera. The trigge-
ring control is activated when the flash-ready signal in the camera's viewfinder
is extinguished. In this event no flash is fired when the camera's shutter is trip-
ped.
On various cameras the triggering control only works in the Program "P" Mode
and in the Shutter Priority Mode "S" (see operating instructions for the camera).
The triggering control can be deactivated on some camera models:
• To do so, press and hold down the flash button
shooting (see camera manual).
The flash-ready signal will again be displayed in the camera's viewfinder when
the shutter release is lightly touched. The camera selects a suitable shutter
speed/aperture combination and a flash is fired when a picture is shot.

14.3 Flash capacitor forming

The flash capacitor built into the flash unit undergoes physical change if the unit
is not switched on for a prolonged period. For this reason it is necessary to
switch the unit on for approximately 10 minutes at least once every three
months. The power supplied by the power source must be sufficient to cause the
flash readiness indicator to light up no more than one minute after the flash unit
is switched on.
