locking ring the direction of the row.
The off-camera adapter is useful when using the product as an off-camera
flash. There is a 1/4" mounting hole at the bottom of the off-camera adapter.
After replacing the adapter, the flash can be used mounting on GODOX
AD-S13 portable light boom, AD-S16 floor light stand, and almost any other
light stand. To install the off-camera adapter,
1. Use a screwdriver (not included) to
remove the four screws at the bottom
of this product. Then take out the
bottom part carefully as illustrated.
2. Install the off-camera adapter at the

FEB: Flash Exposure Bracketing
You can take three flash shots while automatically changing the flash output for each shot from -3 to +3 in 1/3rd
stops. The camera will record three images with different exposures: one exposed according to camera
calculations, one over-exposed and another under-exposed. Over and under exposure amount is user adjustable.
This function helps get correct exposure especially in shooting moving objects or when environmental lights are
complex.
Press < MODE > Mode Selection Button to enter E-TTL mode. The LCD panel will display < ETTL >.
● Press the camera release button halfway to focus. The aperture will be displayed in the viewfinder.
E-TTL Mode
This flash has three flash modes: E-TTL, Manual (M), and Multi (Stroboscopic). In E-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, FEB, FEL, HSS, second curtain sync, modeling flash, control with the camera’s
menu screen.
* Press <MODE> Mode Selection Button and three flash modes will display on the LCD panel one by one with each
pressing.
●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.

Press < S1/S2 > 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.
Optic S1 Secondary Unit Setting
In M manual flash mode, press < S1/S2 > 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

Display Flash Duration
Flash duration refers to the length of time that from flash’s firing to reach the half peak at maximum. The half peak
at maximum is usually expressed as t=0.5. In order to provide the photographer with more concrete data, this
product adopts t=0.1. The difference between t=0.5 and t=0.1 is shown in the following picture.

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.

Flash Mode — M: Manual 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.
Press <MODE> button so that
1<MULTI> is displayed.
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.
Number of Flashes / Flash Frequency = Shutter Speed
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.
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.
● A flash output of 1/1 and 1/2 cannot be set for stroboscopic flash.
● 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.
