3.2 Mounting the Computer and Sensor
Follow these steps to securely mount the computer and its wired sensor:
- Mounting Bracket: Attach the mounting bracket to your handlebar or stem using the provided straps or cable ties. Ensure it is firmly secured and positioned for easy viewing.
- Sensor Placement: Mount the wired sensor to the front fork of your bicycle, ensuring it is aligned with the wheel magnet. The sensor should be positioned so that the magnet passes within 5mm of the sensor as the wheel rotates.
- Magnet Installation: Attach the magnet to a spoke on your front wheel. Adjust its position so it aligns with the sensor.
- Cable Routing: Route the sensor cable along the fork and frame, securing it with cable ties to prevent it from interfering with moving parts or getting snagged. Plug the cable into the computer unit's port.
- Computer Attachment: Slide the M14W computer unit onto the mounting bracket until it clicks into place.
3.3 Initial Settings
After installation, you will need to configure the basic settings:
- Unit Selection: Press the MODE button to cycle through settings. When prompted, select your preferred unit of speed (KM/hr or MPH) using the SET button. Confirm with MODE.
- Wheel Circumference: This is crucial for accurate speed and distance readings.
- Refer to your bicycle tire's sidewall for its size (e.g., 700x23C, 26x1.95).
- Consult a wheel circumference chart (available online or in bicycle shops) to find the corresponding value in millimeters (mm).
- Enter this value into the computer using the SET button to adjust digits and MODE to move to the next digit.
- Initial Odometer Setting (Optional): Some models allow setting an initial odometer value. Follow on-screen prompts if this option appears.
4. Operating Instructions
The M14W features two primary buttons: SET and MODE.
- MODE Button: Used to cycle through different display functions (e.g., Speed, Distance, Ride Time, Odometer). In setting mode, it confirms selections or moves to the next setting.
- SET Button: Used to adjust values during setup (e.g., wheel circumference, time). In some modes, it may reset specific trip data.

5. Maintenance
5.1 Cleaning
Clean the computer unit and sensor regularly with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these can damage the display or casing. The unit has an IP44 rating, meaning it is protected against solid objects larger than 1mm and splashing water from any direction. Avoid submerging the unit in water.
5.2 Battery Replacement
When the display becomes dim or erratic, it's time to replace the CR2 battery. Follow the steps outlined in Section 3.1. Dispose of old batteries responsibly according to local regulations.
5.3 Storage
If storing the bicycle computer for an extended period, it is recommended to remove the battery to prevent leakage and potential damage to the unit.
6. Troubleshooting
If you encounter issues with your M-Wave M14W computer, try the following solutions:
| Problem | Possible Cause / Solution |
|---|---|
| No display or dim display | Battery is low or dead. Replace the CR2 battery. Ensure battery is inserted correctly. |
| No speed/distance reading |
|
| Incorrect speed/distance | Incorrect wheel circumference setting. Re-enter the correct wheel circumference (see Section 3.3). |
| Unit not responding to buttons | Try a soft reset by removing and reinserting the battery. If issues persist, a full reset (using the reset button on the back, if available) might be necessary, which will clear all data. |
