M: Wireless Multiple Flash Shooting in M Manual Flash Mode
Set the sender groups (A, B, C) to M mode and adjust the power output. Receivers will fire automatically based on their assigned group settings.

Wireless Multiple Flash Shooting in Different Flash Modes
Set the sender groups (A, B, C) to different flash modes and adjust the exposure compensa-tion or power output. Receivers will fire automatically based on their assigned group settings.

Wireless Multiple Flash Shooting in Multi Flash Mode
Set the sender to Multi mode and uniformly set the desired power output, flash times, and frequency. The receivers will automatically sync with the sender settings for shooting.

The Reason & Solution of Not Triggering in Godox 2.4G Wireless

1. Disturbed by the 2.4G signal in outer environment (e.g. wireless base station, 2.4G wifi router, Bluetooth, etc.) To adjust the channel CH setting (add 10+ channels) and use the channel which is not disturbed. Or turn off the other 2.4G equipment in working.
2. The flash has not completed recycling, or the recycling speed cannot keep up with the continuous shooting speed. Please downgrade the flash power output. If the flash is in TTL mode, please try to change it to M mode (a pre-flash is needed in TTL mode).
3. The sender and receiver are too close to each other. Please turn on the“close distance wireless modeˮ. For detailed operation, refer to the trigger manual.
4. Low Battery Please charge it in time.
5. The flash’s firmware is an older version Please upgrade the firmware of the flash.
6. The cameraʼs firmware is an older version Please upgrade the firmware of the camera referring to its instruction manual.

Control with the Camera’s Menu (only available in iT30Pro C)

• If the camera flash is attached to an EOS camera that has a camera control function, the flash can be controlled using the camera’s menu screen.
• The functions that can be set are as follows. The available settings vary depending on the flash mode, wireless flash function settings, and other conditions.

Function
Flash Firing	On/Off
E-TTL Balance	Ambience priority/Standard/Flash priority
TTL Metering	Evaluative (Face priority) / Evaluative / Average
Continuous Flash Control	E-TTL shooting every time / E-TTL shooting for the first time

Flash Exposure Compensation

Setting Camera Flash Functions

1. Select <Flash control> or <External Speedlite control>.
2. Select <Flash function settings> or <External func. setting >.
3. The setting screen and items displayed vary depending on the camera.

1. Use the <Clear Settings> option in step 2 to clear all custom function settings of the built-in flash or external flash.
2. If exposure compensation has already been set on the flash, it cannot be adjusted via the camera. To set it using the camera, first set the flash’s exposure compensation to “0”.
3. For custom functions set via either the camera or the flash (except for flash expo-sure compensation), the last setting applied will take effect.

Global Shutter Sync Shooting (only available in iT30Pro)
When used with a global shutter camera, the iT30Pro S supports synchronization across the entire shutter speed range. Compared to traditional High-speed Sync (HSS), global shutter synchronization delivers more effective flash exposure.

1. When flash is used in TTL mode. Compared to a non-global shutter camera, with a global shutter camera, the HSS flash time is shorter (about 2-5 milliseconds), the recycle time is faster, and the camera can take more shots.
2. When flash is used in M (manual) flash mode and you want to use single pulse flash (not HSS) in high-speed shutter (with a shutter speed faster than 1/600), you can adjust the camera’s flash delay time to match the exposure time, so that you can shoot with a more appropriate amount of light. Compared to HSS mode, this mode has a better flash index with the same power.

Flash timing settings: Camera Menu → (Exposure/Color) → [Flash] → [Flash Timing Setting] → [On] → Set the flash timing to the desired value.

ADJ flash timing settings menu:

• On: Adjusts the flash timing manually (0 microseconds to 1000 microseconds).
• Off: Does not adjust the flash timing (the flash will fire in non-single pulse flash when the shut-ter speed is 1/600).

How to Match the Flash and the Shutter
High-speed shutter single-pulse flash requires very strict time alignment. As shown in the figure, the shutter needs to be turned on at the optimal light effect of the flash.

• A: Amount of flash light
• B: Time
• C: Shutter speed
• D: Amount of flash light in 1/128 power F: Exposed amount of flash light
• G: Flash starting timing

Matching method is as follows:

1. Set the flash to M mode, then enter the camera menu.
2. Locate the camera flash timing settings, enable ADJ, and enter the parameters. Parameter values vary by camera and flash model.

The table below uses the iT30Pro S + A9MIII combination as an example(For other global shutter cameras, the alignment time must be determined through real-time debugging. ):

Flash Status Parameter	Value
Wireless OFF	Approx. 140 μs
Wireless ON	Approx. 540 μs

• Set the camera shutter speed to 1/80000s and the flash power to 1/128. (Higher shutter speeds and lower power levels require higher alignment precision; if this combination works, other combinations will generally be applicable.)
• When the shutter speed is fast and the power is high (where flash duration is significantly longer than shutter time), delay the timing to align with the peak flash output.
• If the flash is not synchronized, fine-tune the ADJ parameters until optimal exposure is achieved,

1. If you set the camera’s shutter speed to faster than 1/10000 and take a picture, the brightness and color may vary.
2. For camera equipped with a global shutter image sensor, the HSS icon will not be displayed on the panel regardless of whether the high-speed sync setting is [ON] or [OFF].
3. When the flash is connected to the camera using a sync cord, the camera shoots with a traditional high-speed sync instead of using the global shutter sync, so the distance that the flash’s light can reach is shortened.

Sync Triggering
The interface specification is φ2.5 mm. Insert a sync cord or trigger plug here into the sync cord jack, the flash will be fired synchronously with the camera shutter.

Over-Temperature Protection

• To prevent the flash head from overheating and damage, do not exceed the specified limit of rapid consecutive flashes at 1/1 Full Power.
• If continuous flashing persists beyond the number indicated in the table, Over-Temperature Protection may activate, extending the Recycle Time to over 10 seconds. Should this occur, allow the flash to cool for approximately 10 minutes before resuming operation.
• When the over-temperature protection is started, < > is shown on the display.

Number of flashes that will activate over-temperature protection:

Power Level	Number of continuous flashe
	Without Diffuser	With Diffuser
1/1	30	20
1/2	46	30
1/4	90	60
1/8	150	120
1/16	300	240
1/32	600	400
1/64	1200	1000
1/128	2000	1500

Number of flashes that will activate over-temperature protection in HSS mode:

Power Level	Number of continuous flashe
	Without Diffuser	With Diffuser
1/1	40
1/2	75
1/4	100
1/8
1/16

Troubleshooting

• The flash does not fire: Ensure the flash is securely mounted on the camera hot shoe and the electrical contacts are properly connected. If contacts are dirty, clean them with a dry, lint-free cloth. If the < > or < > indicator does not appear in the camera viewfinder, wait for the flash to recycle. Check the battery level and charge/replace immediately if low.
• Underexposure or overexposure in High-Speed Sync mode: In HSS, the effective flash range is reduced—make sure the subject is within the effective flash range shown on the screen. If the subject is too dark or bright, adjust Flash Exposure Compensation (FEC).
• Wireless not triggering: If the 2.4G environment is disturbed (e.g., 2.4G Wi‑Fi/Bluetooth), change the channel (add 10+ channels) and use a less disturbed channel, or turn off other 2.4G equipment. If the flash has not completed recycling, lower the flash power; if in TTL, try switching to M. If sender and receiver are too close, enable the close-distance wireless mode (refer to the trigger manual). If battery is low, charge it. If firmware is outdated on the flash/camera, upgrade firmware.
• Over-temperature protection: If continuous firing exceeds the limit, over-temperature protection may activate and extend recycle time. Allow the flash to cool for approximately 10 minutes, then resume. When activated, the display shows the < > symbol.
• Firmware upgrade issues: Power off the device, press and hold the < SET > button, connect via the included USB‑C cable to a computer, then upgrade using the Godox G3 software and the latest firmware file.
