5. Troubleshooting

If you encounter issues with your Runleader RL-HM032-BT, consider the following:

• Bluetooth Connection Issues: Make sure Bluetooth is enabled on your phone and the "Moresee" APP is open. Ensure the device is powered by external 12V DC for stable Bluetooth communication. Try restarting both the app and your phone.
• Inaccurate Readings: For RPM, adjust the engine firing pattern settings within the "Moresee" APP if available, to match your engine type for improved accuracy.
• App Not Responding: Close and reopen the "Moresee" APP. If the issue persists, try reinstalling the app.
