5. Maintenance
To ensure the longevity and optimal performance of your AODELAN E4:
- Keep the device clean and free from dust and moisture. Use a soft, dry cloth for cleaning.
- Avoid exposing the device to extreme temperatures or direct sunlight for extended periods.
- Remove batteries if the device will not be used for an extended period to prevent leakage.
- Store the device in a cool, dry place.
6. Troubleshooting
If you encounter issues with your AODELAN E4, refer to the following common troubleshooting steps:
- Device not powering on: Check if the AAA batteries are correctly inserted and have sufficient charge. Replace batteries if necessary.
- Flash not triggering:
- Ensure the E4 is securely mounted on the camera's hot shoe.
- Verify that the E4 and the flash unit are set to the same channel and group.
- Check the flash unit's power and readiness.
- Confirm that the camera's flash settings are appropriate for external flash use.
- Incorrect exposure in TTL mode: Ensure the flash unit is compatible with TTL and that its settings are not overriding the E4's commands. Check for any exposure compensation set on the camera or flash.
- HSS not working: Confirm that both your camera and flash unit support High-Speed Sync. Ensure the camera's shutter speed is set above its normal sync speed.
- Limited range or interference: Ensure there are no major obstructions between the E4 and the flash units. Avoid environments with strong 2.4 GHz interference.
If problems persist after attempting these steps, please contact AODELAN customer support for further assistance.
