To resolve a Bluetooth error message on the Hanna Instruments HI98494 at startup, try the following solutions:

1. Ensure Firmware is Updated – Upgrade the device to at least Firmware Version 3.0, which is required for Bluetooth compatibility.
2. Check Hanna Lab App Version – Make sure you are using version 3.0 or higher of the Hanna Lab App on your iOS or Android device.
3. Restart the Device – Turn the HI98494 off and back on to reset the Bluetooth connection.
4. Verify Device Compatibility – Ensure your mobile device supports Bluetooth connections with the HI98494.
5. Restore Factory Settings – If other solutions fail, reset the device by selecting "Restore factory settings" in the menu.

If the issue persists, further troubleshooting may be needed.
