FEC: Flash Exposure Compensation
With FEC function, this flash 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:
1
Press the
SET
Button and
the flash exposure compen-
sation amount will be high-
lighted on the LCD panel.
2
Turn the Select Dial to set
the amount.
•
“0.3”means 1/3 step,
“0.7”means 2/3 step.
•
To cancel the flash expo-
sure compensation, set
the amount to “+0”.

Press <
SET
> button again
to confirm the setting.
High-Speed Sync
High Speed Sync (Hss flash) enables the flash to synchronize with
all camera shutter speeds. This is convenient when you want to
use aperture priority for fill-flash portraits.
Press the <SYNC> button to turn on high-speed sync flash and
< > is displayed. Then, adjust the camera’s shutter to achieve
high-speed sync flash.
• With high-speed sync, the faster the shutter speed, the
shorter the effective flash range.
• Multi flash mode cannot be set in high-speed sync mode.
• Over-temperature protection may be activated after 15
consecutive high-speed sync flashes.
• Try to avoid using high-speed sync flash, which will cut
short flash tube’s lifetime.
Note
: With the Panasonic cameras in wireless control
mode, the High-Speed Sync may not sync fire.
Second-Curtain Sync
With a slow shutter speed, you can create a light train following
the subject. The flash fires right before the shutter closes.
• Setting the Second-Curtain Sync function on the camera menu,
please read camera instruction manual.
M: Manual Flash
The flash output is adjustable from 1/1 full power to 1/128th pow-
er in 1/3rd stop increments. To obtain a correct flash exposure,
use a hand-held flash meter to determine the required flash out-
put.
1
Press <
MODE
> button so
that <
M
> is displayed.
2
Turn the Select Dial to
choose a desired flash out-
put amount. In high-
speed sync mode, the ad-
justable flash 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 flash output.
For example, when you decrease the flash output to 1/2, 1/2-0.3,
or 1/2- 0.7, and then increase the flash output to more than 1/2,
1/2+0.3, 1/2+0.7, and 1/1 will be displayed.

functions can be achieved.
Optical S1 Secondary Unit Setting
In M manual flash mode, press the <
SLAVE
> button so that this
flash can function as an optic S1 secondary flash with optic sen-
sor. With this function, the flash will fire synchronously when the
main flash fires, 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 flash can also function as
an optic S2 secondary flash with optic sensor in M manual flash
mode. This is useful when cameras have pre-flash function. With
this function, the flash will ignore a single “preflash” from the
main flash and will only fire in response to the second, actual flash
from the main unit.
• S1 and S2 optic triggering and off camera high-speed
mode are only available in M manual flash mode.
