3. Sensor and Magnet Installation
For accurate speed and distance measurements, the wireless sensor and wheel magnet must be correctly installed.

Solution: Check battery installation. Replace the CR2032 battery if necessary. Ensure the battery is inserted with correct polarity. - No Speed Reading:
Solution: Verify that the wireless sensor is correctly positioned on the front fork and the magnet is securely attached to a spoke. Ensure the gap between the magnet and sensor is less than 5mm. Check the sensor battery (if applicable, some wireless sensors have their own battery). - Inaccurate Readings:
Solution: Confirm that the wheel circumference setting is correct. Ensure the magnet and sensor alignment is precise. Avoid strong electromagnetic interference sources. - Unit Not Responding:
Solution: Remove the battery, wait for 30 seconds, then reinsert it. This may reset the unit. If issues persist, contact customer support.
