It is useful in situations where minor adjusting of the TTL system is
needed based on the environment.
Setting FEC:
Turn the Select Dial to set the

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.
High-Speed Sync
High Speed Sync (FP 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.
Choose the < > button:
Press the <SYNC> button to turn on high-speed sync function.
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.
The flash output is adjustable from 1/1 full power to 1/128th power
in 1/3rd stop increments. To obtain a correct flash exposure, use a
hand-held flash meter to determine the required flash output.

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.
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 sensor.
With this function, the flash will fire synchronously when the main
flash fires, the same effect as that by the use of radio triggers. 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.
In the M mode, high-speed sync and second curtain sync functions
can be achieved.
