Power Management
Use Power Switch to power the flash unit on (Long press the
button for one second) or off. Turn off if it will not be used for an
extended period of time. Setting as a master flash, it will turn the
power off automatically after a certain period (approx. 90 seconds)
of idle use. Pressing the camera shutter halfway or pressing any
flash button will wake up the flash unit. Setting as a slave flash, it
will enter sleep mode after a certain period (adjustable, 60 minutes
by default) of idle use. Pressing any flash button will wake it up.
Disabling Auto Power Off function is recommended
when the flash is used off camera. (C.Fn-ST, Page 43)
Flash Mode: TTL Autoflash
This flash has three flash modes: TTL, Manual (M), and Multi
(Stroboscopic). In TTL mode, the camera and the flash will work
together to calculate the correct exposure for the subject and the
background. In this mode, multiple TTL functions are available:
FEC, HSS, second curtain sync, etc.
* Press <MODE> Mode Selection Button and three flash modes will
display on the LCD panel one by one with each pressing.
TTL Mode
Press <MODE> Mode Selection Button to enter TTL mode. The
LCD panel will display <TTL>.
● Press the camera release button halfway to focus.
● When the shutter button is fully pressed, the flash will fire a pre-
flash that the camera will use to calculate exposure and flash
output the instant before the photo is taken.
Display“HI”: When the flash output value is up to the maximum
value, “HI”will be displayed and blinking for 3 seconds. Adjust
the camera’s parameters if underexposure appears.
Display“Lo”: When the flash output value is up to the minimum
value, “Lo”will be displayed and blinking for 3 seconds. Adjust the
camera’s parameters if overexposure appears.

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:
Turn the Select Dial to set the
2amount.
● “0.3”means 1/3 step,
“0.7”means 2/3 step.
● To cancel the flash
exposure compensation,
set the amount to “+0”.
Press < SET > button again
3to confirm the setting.
Press the SET Button and
1the flash exposure
compensation amount will be
highlighted on the LCD panel.
● 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.
M: Manual Flash
Press < MODE > button so
1that < M > is displayed.
Turn the Select Dial to choose
2a desired flash output amount.
In high-speed sync mode,

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.

Multi: Stroboscopic Flash
With stroboscopic flash, a rapid series of flashes is fired. It can be
used to capture a multiple images of a moving subject in a single
photograph.
You can set the firing frequency (number of flashes per sec.
expressed as Hz), the number of flashes, and the flash output.
Long press the <MODE>
1button for 2 seconds so that
<Multi> is displayed.
Turn the Select Dial to choose
2a desired flash output.
Calculating the Shutter Speed
During stroboscopic flash, the shutter remains open until the firing
stops. Use the formula below to calculate the shutter speed and set
it with the camera.
For example, if the number of flashes is 10 and the firing frequency is
5 Hz, the shutter speed should be at least 2 seconds.
Number of Flashes / Flash Frequency = Shutter Speed
To avoid overheating and deteriorating the flash head, do not
use stroboscopic flash more than 10 times in succession.
After 10 times, allow the camera flash to rest for at least 15
minutes. If you try to use the stroboscopic flash more than 10
times in succession, the firing might stop automatically to
protect the flash head. If this happens, allow at least 15
minutes’ rest for the camera flash.
● Stroboscopic flash is most effective with a highly reflective
subject against a dark background.
● Using a tripod and a remote control is recommended.
● Stroboscopic flash can be used with“buLb”.
● If the number of flashes is displayed as “--”, the firing will
continue until the shutter closes or the battery is
exhausted. The number of flashes will be limited as shown
by the following table.

Bounce Flash
By pointing the flash head toward a wall or ceiling, the flash will
bounce off the surface before illuminating the subject. This can
soften shadows behind the subject for a more natural-looking shot.
This is called bounce flash.
To set the bounce direction, hold the flash head and turn it to a
satisfying angle.
● If the wall or ceiling is too far away, the bounced flash might
be too weak and result in underexposure.
● The wall or ceiling should be a plain, white color for high
reflectance. If the bounce surface is not white, a color cast
may appear in the picture.
Creating a Catchlight
With the catchlight panel, you can create a catchlight in the subject’s
eyes to add life to the facial expression.
