Foreword

Thank you for purchasing this XProC wireless flash trigger. This trigger is suitable for Canon cameras to control Godox flashes with the X system, including camera flashes, outdoor flashes, and studio flashes. It can also control Canon original speedlites with the coordination of the X1R-C receiver. Featuring multi-channel triggering, stable signal transmission, and sensitive reaction, it offers photographers unparalleled flexibility and control over their strobist setups. The flash trigger is applicable to hot shoe-mounted Canon EOS series cameras, as well as cameras with PC sync sockets.

With the XProC wireless flash trigger, high-speed synchronization is available for most camera flashes supporting E-TTL II. The maximum flash synchronization speed is up to 1/8000s*.

*1/8000s is achievable when the camera has a maximum shutter speed of 1/8000s.

TCM Function

The TCM transform function is a unique Godox feature that converts TTL flash values to power output values in M mode.

1. Set the flash trigger to TTL mode and attach it to the camera.
2. Press the shutter for shooting.
3. Long press the <TCM> button; the flash value in TTL mode will be converted to the power output value in M mode (the displayed minimum value is the set Min. value).

Press the <MENU> button to enter C.Fn SHOOT. Press the <SET> button to choose one-shoot or multi-shoots. Press the <MENU> button again to return to the main menu.

• One-shoot: When shooting, select one-shoot. In M and Multi modes, the master unit only sends triggering signals to the slave unit, which is power-saving and suitable for solo photography.
• Multi-shoots: When shooting, select multi-shoots. The master unit sends parameters and triggering signals to the slave unit, suitable for group photography. However, this function consumes power quickly.
• APP: Only sends triggering signals when the camera is shooting (control flash parameters via smartphone APP).

1. This table lists only tested camera models; not all Canon EOS series cameras are included. Self-testing is recommended for other camera models.
2. Godox reserves the right to modify this table.
3. Cameras released before 2012 may not have TTL mode in their D and E groups.

Restore Factory Settings

Synchronously press the two middle function buttons. "RESET" will be displayed on the LCD panel when the restore is complete.

Firmware Upgrade

This flash trigger supports firmware upgrades via the Type-C USB port. Update information will be posted on the official website.

• The USB connection cable is not included. Use a Type-C USB connection cable.
• The Godox G2 software is required for firmware upgrades. Download and install the "Godox G2 firmware upgrade software" before upgrading. Then, select the relevant firmware file.

Troubleshooting

• Unable to trigger flash or camera shutter: Ensure batteries are installed correctly and the Power Switch is ON. Check if the transmitter and receiver are set to the same channel, if the hot shoe mount or connection cable is properly connected, or if the flash triggers are set to the correct mode.
• Camera shoots but does not focus: Check if the camera or lens focus mode is set to MF. If so, set it to AF.
• Signal disturbance or shooting interference: Change the channel setting on the device.

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

1. Disturbed by 2.4G signal in the environment (e.g., wireless base station, Wi-Fi router, Bluetooth, etc.): Adjust the channel (CH) setting on the flash trigger (add 10+ channels) and use a less disturbed channel. Alternatively, turn off other active 2.4G equipment.
2. Flash recycle time or continuous shooting speed limit reached (flash ready indicator is lit) or flash is in overheat protection or abnormal state: Downgrade the flash power output. If the flash is in TTL mode, try switching to M mode (a pre-flash is required in TTL mode).
3. Flash trigger and flash are too close: Set the C.Fn-DIST to 0-30m for "close distance wireless mode" (<0.5m).
4. Low battery status on flash trigger and receiver: Replace the batteries. It is recommended to use 1.5V disposable alkaline batteries for the flash trigger.

Caring for Flash Trigger

• Avoid sudden drops: The device may fail to work after strong shocks, impacts, or excessive stress.
• Keep dry: The product is not waterproof. Malfunction, rust, and corrosion may occur and be irreparable if soaked in water or exposed to high humidity.
• Avoid sudden temperature changes: Condensation can occur if the transceiver is moved from a warmer indoor environment to a colder outdoor environment in winter. Place the transceiver in a handbag or plastic bag beforehand.
• Keep away from strong magnetic fields: Strong static or magnetic fields produced by devices like radio transmitters can cause malfunction.
