5. Troubleshooting
5.1 Connectivity Issues
- No connection: Ensure the ST-E10 is securely mounted on the camera's multi-function shoe and the camera is powered on. Verify that the Speedlites are also powered on and set to receive signals.
- Intermittent connection: Radio-wave transmission can be affected by environmental interference. Try changing the wireless channel on both the transmitter and Speedlites. Ensure there are no large metallic objects or other strong radio sources between the transmitter and Speedlites.
- Flash not firing: Check the flash settings on your camera or the Canon Camera Connect app to ensure the Speedlites are enabled and set to the correct mode (e.g., E-TTL II, Manual). Confirm that the Speedlites have sufficient battery power.
