camera’s automatic exposure system will automatically regard the changed dia-
phragm as the normal working aperture.
After the exposure do not forget to reset the TTL flash exposure cor-
rection back to the normal value on the camera!
Setting the correction value
• Mount the flash unit on the camera.
• Switch on the flash unit and the camera.
• Touch the camera’s shutter release lightly so that data can be exchanged
between the flash unit and the camera.
• Continue depressing the “Select” key combination (= “Mode” key + “Zoom”
key) until
EV
(exposure value = stop value) is indicated on the LC display.
Alongside
EV
, the set correction value will flash on the display.
• While the displayed correction value is flashing a positive correction value
can be set with the “Zoom” key, or a negative value with the “Mode” key.
The setting range for the correction value covers -3 to +3 f-stops in one-third
stop increments.
The setting becomes immediately effective and after approx. 5 seconds the
LC display is switched back to its normal state.
EV
flashes alongside the aperture symbol on the LC display of the flash unit
when a correction value has been set.
Various cameras offer the facility to set a manual correction value on
the camera itself. With such cameras we recommend that the correc-
tion value be set either on the camera or the flash unit.
Deleting manual TTL exposure correction on the flash unit
• Continue depressing the “Select” key combination (= “Mode” key + “Zoom”
key) until
EV
is indicated on the LC display.
• Alongside
EV
the set correction value will flash on the display.
• While the correction value is flashing the “Zoom” or “Mode” keys permit to
delete the correction value by setting it to
0.0
.

The setting becomes immediately effective and after approx. 5 seconds the
LC display is switched back to its normal state.
Correction value setting on the camera
With various cameras (e.g. PowerShot G1, G2, G3 and Pro 90IS) the
manual correction value for flash exposure must always be set on the
camera. This setting is not possible or ineffective on the flash unit.
Please refer to the corresponding explanations in the camera’s operat-
ing instructions.
4.3 Correct exposure indication (Fig. 4)
„o.k.“ correct exposure confirmation only appears on the LC display of the
flash unit if the shot was correctly exposed in TTL or E-TTL flash mode!
Correct exposure is not indicated in M or MLo manual mode.
If, in TTL or E-TTL mode, „o.k.“ is not displayed after the exposure, then this
means that the shot was underexposed. The shot will then have to be re-
peated with the next smaller fnumber (e.g. f/8 instead of f/11) or the flash-
to-subject distance or reflecting surface must be reduced (e.g. with bounce
flash). Please note the maximum flash range indicated on the LC display of
the flash unit (see 5.4.1).
Correct exposure is not indicated in the camera’s viewfinder!
4.4 Manual flash mode
Some cameras automatically change the flash unit to TTL or E-TTL flash
mode when in „Green Full Auto Mode“ or in one of the „programmed
image control modes“. Manual flash mode is then no longer possible.
There is no correct exposure confirmation on the LC display of the
flash unit when in manual flash mode!
Set „Av“ aperture priority or the „M“ or „X“ manual modes on the camera.
Select the aperture and shutter speed (with „M“) on the camera according to
the given photographic situation (see the camera’s operating instructions).
