The different flash modes, e.g. TTL, manual flash
mode M and MLo, are selected by repeated de-
pression of the "MODE" button. The selected flash
mode flashes on the LC display of the flash unit.

4.1 TTL flash mode

The TTL flash mode is a very simple way to achieve
excellent flash shots. In this mode exposure read-
ings are taken by a sensor built into the camera
which measures the light reaching the film through
the camera lens (TTL). The electronic control circuit
within the camera transmits a stop signal to the
flash unit as soon as the film has been exposed by
the correct amount of light, thereby instantly inter-
rupting the flash. The advantage of this flash mode
is that all factors influencing correct exposure of the
film (filters, change of aperture and focal length
with zoom lenses, extensions for close-ups, etc.) are
automatically taken into account. You need not
worry about setting the flash, the camera's elec-
tronic system automatically determines the correct
amount of flash light required. For the maximum
flash range please observe the distances given in
the LC display of the flash unit (see section 5.7). If
flash exposure was correct, the LC display of the
flash unit indicates "o.k." for about 3 sec. (see sec-
tion 5.2).
Normally, the TTL flash mode is supported by all
camera modes, e.g. Program "P" (Full Auto Mode
or "Green Square"), Aperture Priority Mode ("A"
or "Av"), Shutter Priority Mode ("T", "Tv" or "S"),
programmed image control or scene modes
(landscape, portrait, sports, etc.), Manual Mode
"M", etc.
Various digital cameras do not support the
"normal" TTL flash mode. In this case it is
necessary to select the given advanced va-
riant of the TTL flash mode on the flash unit.
Setting on the flash unit
• Switch on the flash unit.
• Continue depressing the "MODE" button until
"TTL" flashes on the display.
