FEC: Flash Exposure Compensation
With FEC function, this ash can adjust from -3 to +3 in 1/3rd
stops. It is useful in situations where minor adjusting of the TTL
system is needed based on the environment.
Setting FEC:
1Press the SET Button and
the ash exposure compen-
sation amount will be high-
lighted on the LCD panel.
2Turn the Select Dial to set
the amount.
•“0.3”means 1/3 step,
“0.7”means 2/3 step.
•To cancel the ash expo-
sure compensation, set
the amount to “+0”.
3Press < SET> button again
to conrm the setting.
High-Speed Sync
High Speed Sync (Hss ash) enables the ash to synchronize with
all camera shutter speeds. This is convenient when you want to
use aperture priority for ll-ash portraits.
Press the <SYNC> button to turn on high-speed sync ash and
< > is displayed. Then, adjust the camera’s shutter to achieve
high-speed sync ash.
•With high-speed sync, the faster the shutter speed, the
shorter the effective ash range.
•Multi ash mode cannot be set in high-speed sync mode.
•Over-temperature protection may be activated after 15
consecutive high-speed sync ashes.
•Try to avoid using high-speed sync ash, which will cut
short ash tube’s lifetime.
Note: With the Panasonic cameras in wireless control
mode, the High-Speed Sync may not sync re.
Second-Curtain Sync
With a slow shutter speed, you can create a light train following
the subject. The ash res right before the shutter closes.
•Setting the Second-Curtain Sync function on the camera menu,
please read camera instruction manual.
M: Manual Flash
The ash output is adjustable from 1/1 full power to 1/128th pow-
er in 1/3rd stop increments. To obtain a correct ash exposure,
use a hand-held ash meter to determine the required ash out-
put.
1Press < MODE> button so
that <M> is displayed.
2Turn the Select Dial to
choose a desired ash out-
put amount. In high-
speed sync mode, the ad-
justable ash range is
1/16~1/1.
Flash Output Range
The following table makes it easier to see how the stop changes
in terms of f/stop when you increase or decrease the ash output.
For example, when you decrease the ash output to 1/2, 1/2-0.3,
or 1/2- 0.7, and then increase the ash output to more than 1/2,
1/2+0.3, 1/2+0.7, and 1/1 will be displayed.

In the M mode, high-speed sync and second curtain sync
functions can be achieved.
Optical S1 Secondary Unit Setting
In M manual ash mode, press the < SLAVE> button so that this
ash can function as an optic S1 secondary ash with optic sen-
sor. With this function, the ash will re synchronously when the
main ash res, the same effect as that by the use of radio trig-
gers. This helps create multiple lighting effects.
Optical S2 Secondary Unit Setting
Press the < SLAVE> button so that this ash can also function as
an optic S2 secondary ash with optic sensor in M manual ash
mode. This is useful when cameras have pre-ash function. With
this function, the ash will ignore a single “preash” from the
main ash and will only re in response to the second, actual ash
from the main unit.
•S1 and S2 optic triggering and off camera high-speed
mode are only available in M manual ash mode.
