• Ensure the sensor cable is securely connected to the bracket and the computer.
• Verify the wheel size setting is correctly configured.

Display Not Working / Blank

• Check the battery. Replace it if necessary.
• Ensure the computer is securely seated in its bracket.

Inaccurate Readings

• Re-check the wheel size setting for accuracy.
• Ensure the magnet and sensor are not loose and maintain consistent alignment.
