• The camera flash will fire a preflash and lock the flash exposure setting
once the button is pressed.
- If the subject is too far away and underexposure, the icon will blink in the viewfinder. Move closer to the subject and try the FE lock again.
- If is not displayed on the LCD panel, the FE lock cannot be set.
- If the subject is too small, the FE lock might not be very effective.
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.
-
Press Function Button 2 < SYNC> so that < ****> is displayed.
-
Check that < ****> is displayed in the viewfinder.
- If you set a shutter speed that is the same as or lower than the camera’s maximum flash sync speed, < ****> will not be displayed in the viewfinder.
- With high-speed sync, the faster the shutter speed, the shorter the effective flash range.
- To return to normal flash, press button again.Then < ****> will disappear.
- Multiflash mode cannot be set in high-speed sync mode.
- Over-temperature protection may be activated after 30 consecutive high-speed sync flashes.

Optic Sl 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 the use of radio triggers. This helps create multiple lighting
effects.
Optic S2 Secondary Unit Setting
Press <S1/S2> button so that this flash can also function as an optic S2
secondary flash with the optic sensor in M manual flash mode. This is useful
when cameras have a 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.
• Sl and S2 optic triggering is only available in M manual flash mode.
Multi: Stroboscopic Flash
With stroboscopic flash, a rapid series of flashes is fired. It can be used to
capture 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 button so that is displayed.
-
Set the flash frequency and flash times.
• Press the Function Button 2 2 to select the flash times. Turn the
Select Dial to set the number.
• Press the Function Button 3 to select the flash frequency. Turn the
Select Dial to set the number.
-
Turn the Select Dial to choose the desired flash output. After you finish the setting, press Set Button and all the settings will be displayed.
Calculating the Shutter Speed
During the 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 1 O times in succession. After 1 O time, allow the camera lash
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 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.

Wireless Flash Shooting: Radio (2.4G) Transmission
-
When the camera’s shooting mode is set to a fully automatic mode or an Image Zone mode, the operations in this chapter are not available. Set the camera’s shooting mode to P/Tv/Av/M/B (Creative Zone Mode).
-
The TT685IIC attached to the camera is called the transmitter unit, and a TT685IIC that is wirelessly controlled is called the receiver unit.
-
You can also wirelessly control the TT685IIC set as the receiver unit with the transmitter X1T-C (sold separately). For details on setting the transmitter unit functions, see the transmitter’s instructions.
Using a flash (transmitter/receiver) with a radio transmission wireless
shooting function makes it easy to shoot with advanced wireless multiple
flashes lighting, in the same way as E-TTL I autoflash shooting.
The basic relative position and operation range is as shown in the picture.
You can then perform wireless E-TTL II autoflash shooting just by setting the
transmitter unit to .
Positioning and Operation Range (Example of wireless flash shooting)
- Autoflash Shooting with One Receiver Unit
- Use the supplied mini stand to position the Receiver unit.
- Before shooting, perform a test flash and test shooting.
- The transmission distance might be shorter depending on the conditions such as positioning of Receiver units, the surrounding environment, and weather conditions.
Wireless Multiple Flash Shooting
You can divide the Receiver units into two or three groups and perform an
E-TTL II autoflash while changing the flash ratio (factor). In addition, you
can set and shoot with a different flash mode for each firing group, for up to
4 groups.

The Reason & Solution of Not Triggering in Godox 2.4G Wireless
-
Disturbed by the 2.4G signal in the outer environment (e.g. wireless base station, 2.4G wifi router, Bluetooth, etc.)
→ To adjust the channel CH setting on the flash trigger (add 10+ channels) and
use the channel which is not disturbed. Or turn off the other 2.4G equipment
in working.
-
Please make sure that whether the flash has finished its recycling or caught up with the continuous shooting speed or not(the flash ready indicator is lightened) and the flash is not under the state of over-heat protection or other abnormal situation.
→Please downgrade the flash power output. If the flash is in TTL mode, please
try to change it to M mode(a preflash is needed in TTL mode).
-
Whether the distance between the flash trigger and the flash is too close or not (<0.5m)
→ Please turn on the “close distance wireless mode” on the lash trigger X2 &
X1 series: press the test button and hold on, then turn it on until the flash-
ready indicator blinks 2 times. XPro series: Set the C.Fn-DIST to 0-30m.
-
Whether the flash trigger and the receiver end equipment are in the low battery states or not
→Please replace the battery(the flash trigger is recommended to use a 1.5V
disposable alkaline battery).
Other Applications
Sync Triggering
The Sync Cord Jack is a C!>2.5mm plug. Insert a trigger plug here and the
flash will be fired synchronously with the camera shutter.
Auto Focus Assist Beam
In poorly-lit or low-contrast shooting environments, the built-in autofocus
assist beam will automatically light on to make it easier for autofocus. The
beam will light up only when autofocus is difficult and get out as soon as the
autofocus becomes correct. If you want to turn off the autofocus assist beam,
set the “AF” to “OFF” on the C.Fn settings.
• If you find the autofocus assist beam does not light up, this is because the
camera has got the correct autofocus.

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.
-
Point the flash head upward by 90°.
-
Pull out the wide panel.
The catchlight panel will come out at the same time.
-
Push the side panel back in.
• Push in only the wide panel.
• Follow the same procedures as for bounce flash.
Notes:
- Point the flash head straight ahead and then upward by 90°. The catchlight will not appear if you swing the flash head left or right.
- For maximum catchlight effect, stay 1.5m/4.9ft away from the subject.
ZOOM: Setting the Flash Coverage
The flash coverage can be set automatically or manually. It can be set to
match the lens focal length from 20mm to 200mm.
In Manual Zoom mode, press the button.
If you set the flash coverage manually, make sure it covers the lens focal
length so that the picture will not have a dark periphery.
Low Battery Warning
If the battery power is low, < ] > will appear and blink on the LCD panel.
Please replace the battery immediately.
