Updating Firmware

Introduction

The FJ-X3 Wireless Trigger is designed with a USB-C port for firmware updates and charging. Future updates may enhance performance, modify menu options, and adjust layouts. It is recommended to visit fjwestcott.com/firmware to ensure your FJ-X3 has the latest firmware.

Installing the Firmware

1. Visit fjwestcott.com/firmware to find and download the latest firmware ZIP file. (Note: Some browsers automatically unzip files; if this occurs, skip to Step 3.)
2. Unzip the downloaded file and open the extracted folder.
3. IMPORTANT: Read all files within the extracted folder, including README and Changelog.
4. Ensure the FJ-X3 is turned OFF.
5. Connect the USB-A to USB-C cable to the FJ-X3's USB-C port.
6. On the FJ-X3, press and hold the SYNC•MENU button located below the screen.
7. While holding the button, connect the USB-A to USB-C cable to your computer's USB-A port. The Wireless Signal Indicator light on the FJ-X3 will illuminate red, indicating your computer has recognized the connection. You can release the button now. Most operating systems will present the FJ-X3 as an external device. macOS may show an icon on the desktop or in a Finder window.
8. Locate the .BIN firmware file on your computer and drag it to the FJ-X3 (which should appear as an external device).
9. Once the file copy is complete, EJECT the external device from your computer.
10. Unplug the USB-A to USB-C cable from both the computer and the FJ-X3.
11. Long press the Power button on the FJ-X3 to initiate the firmware update process.

Important Precautions

• If the FJ-X3 does not appear as an external device after connecting to your computer, disconnect the USB cable from both devices, restart your computer, and try the firmware update process again.
• It is recommended to perform the firmware update only when the connected computer's power level is 25% or higher. Loss of power during the update could render the FJ-X3 inoperable, requiring professional repair.
• Removing the USB cable from the FJ-X3 without properly ejecting the device from your computer could render the trigger inoperable and require professional repair.
• Copying the firmware file from your computer to the FJ-X3 may take several minutes and might occasionally halt. If this occurs, close the copy progress window and attempt the copy again. Persistent copying issues may require restarting your computer.
