Viawlinder lndicatsr
Flash operation and flash battery-check are indi-
cated by a red light, located under the left edge of
the focusing screen. It is operative only when a
dedicated flash is connected to the TTL socket. It
indicates three separate states as described below.
Beady Signal
A steady red light indicates that the flash unit is
charged and ready to be fired. Absence of any sig-
nal indicates the need for fresh batteries.
'' Gonlirnation Signal
A flashing red light occurring forjust over a sec-
ond immediately after exposure confirms that the
light output was sufficient for a proper exposure.
It then remains dark until the flash unit has
recharged. The steady red light will then reappear
indicating operative status again. The time of
reappearance however may vary according to the
condition of the batteries.
No Result Signal
Absence of the flashing confirmation signal after
exposure indicates that the flash emitted was not
sufficient for correct exposure. The aperture must
then be opened rqore or the flash distance to the
subject reduced. Changing to a faster film is also
a possibility.
