6.2 Slave mode with
preflash suppression SL
This slave mode is specifically intended for digital
cameras working with preflash technology. In this
mode, the slave flash unit is not triggered by the
measuring preflash but only by the main flash
from the camera’s internal flash unit at the moment
of exposure. The light output of the slave is con-
trolled by way of the set flash mode (EASY, auto-
matic A or manual M mode).
The red-eye reducing preflash function must
not be activated on the camera! The slave
flash unit will only react to light pulses from
the controller within a specific time (fractions
of a second) , thus making it almost insensitive
to the flash light of other photographers that
are not working with preflash technology.
Settings on the slave flash unit
Repeatedly depress the
pre-select and
“MODE” keys simultaneously until the symbol
SL
flashes on the LC display. The setting instantly
becomes effective and is automatically stored after
5 s.
If necessary, you can modify the suppression
of the preflash and reset the time between
preflash and main flash for manual adapta-
tion to your camera; see also Chapter 11.3.
6.3 Adapted slave mode SL
This slave mode permits individual adaptation of
the slave to the technology of the camera’s internal
flash unit. It permits one or more red-eye reducing
preflashes and one or more measuring preflashes
of the integrated flash unit to be taken into ac-
count. The slave is triggered at the same time as
the camera-internal flash unit firing the main flash
for exposure. The light output of the slave unit is
controlled by the selected flash mode (EASY, auto-
matic A or manual M mode).
Adapting the flash unit
• Activate the integrated flash unit. If necessary,
switch on the camera’s red-eye reducing pre-
flash function.
• Turn on the flash unit by the main switch and wait
for the flash readiness indicator to light up.
