Maintenance
To ensure the longevity and optimal performance of your 1Mii SafeFly Dot, follow these maintenance guidelines:
- Keep the device dry. Avoid exposure to moisture, rain, or liquids.
- Do not expose the device to extreme temperatures (hot or cold).
- Clean the device with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
- Store the device in a cool, dry place when not in use.
- Avoid dropping or subjecting the device to strong impacts.
Troubleshooting
If you encounter issues with your SafeFly Dot, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No audio output/input. | Incorrect mode, loose connection, low volume. | Ensure the device is in the correct TX or RX mode. Check that all 3.5mm audio connections are secure. Verify volume levels on both the SafeFly Dot and the connected audio device/headphones. |
| Cannot pair with a Bluetooth device. | SafeFly Dot not in pairing mode, device too far, interference. | Ensure the SafeFly Dot's TX or RX LED is flashing red-blue (pairing mode). Place the Bluetooth device close to the SafeFly Dot. Turn off other Bluetooth devices nearby to reduce interference. Try resetting both devices. |
| Audio latency (delay). | Connected device does not support aptX Low Latency. | For minimal delay, ensure both the SafeFly Dot and your Bluetooth headphones/speakers support aptX Low Latency (aptX-LL). If not, audio will default to another codec with higher latency. |
| Poor audio quality. | Interference, low-quality codec, source audio issue. | Ensure there are no significant obstructions or strong interference sources. Verify that both devices support high-quality codecs like aptX-HD. Test with a different audio source. |
| Phone calls not working. | Device in TX mode, incorrect connection. | The built-in microphone and call function are only available in RX mode. Ensure your phone is connected to the SafeFly Dot in RX mode. |
