MANUAL FLASH OPERATION - M
In manual flash mode, flash output is always fixed at the level set.
Possible ways of adjusting to the photographic situation include
using the guide number calculation and aperture setting on the
camera or by selecting an appropriate output level. The output
levels range from full power to 1/256 (corresponds to 8 aperture
steps).
• The status LED 9d lights up as an indication that the output
levelcan be set.
Setting a partial light output stage
Turn the setting dial 9 so that the desired output stage is opposite
the Status LED 9a . If you want to have full output again you have to
reset the output value to
1
WIRELESS OPERATION - SD/SF
With these two modes the flash unit can be fired wirelessly through
the flash burst of the main flash unit attached to or connected to
the camera.
The two versions are designed to match the firing time to whether
the main flash unit connected to the camera works with pre-flash
–
SD
, or without it -
SF
. This ensures that this flash unit, i.e. the
one not connected to the camera is only fired by the main flash
burst.
Both versions correspond to
M
mode with respect to controlling
the flash illumination, i.e. flash output is always fixed at the level
set. Reduced output levels are set in the same way.
• The status LED 9d lights up in white as an indication that the
flash output can be set.
