3.3. Installing the Speed Sensor and Magnet
Mount the wireless speed sensor on the front fork, ensuring it is aligned with the wheel magnet. The magnet should be attached to a spoke on the front wheel. Position the sensor and magnet so that the gap between them is approximately 3-5 mm when the magnet passes the sensor. Secure the sensor with zip ties.
3.4. Initial Settings (Wheel Size, Time, Units)
Upon first use or after battery replacement, the computer will prompt you to set basic parameters:
- Wheel Size: Refer to your tire's sidewall for the ETRTO size (e.g., 700x23c) and consult the wheel circumference chart in the appendix (or online) to enter the correct value in millimeters. This is crucial for accurate speed and distance readings.
- Time: Set the current time (12h/24h format).
- Units: Select your preferred units for speed and distance (km/h and km, or mph and miles).
Use the buttons (typically MODE and SET) to navigate and adjust values. Confirm settings as prompted by the display.
4. Operating the Cycle Computer
4.1. Button Functions
- MODE Button: Press to cycle through different display modes (e.g., Current Speed, Average Speed, Max Speed, Trip Distance, Odometer, Ride Time, Clock). Hold to enter settings menu.
- SET Button: Press to confirm selections or reset values in certain modes. Hold to clear trip data.
4.2. Display Modes
The Comp 150 displays various data points. Press the MODE button to switch between them:
- SPD (Current Speed): Your real-time speed.
- AVS (Average Speed): Average speed for the current trip.
- MXS (Maximum Speed): Highest speed recorded during the current trip.
- DST (Trip Distance): Distance covered during the current trip.
- ODO (Odometer): Total accumulated distance.
- TM (Ride Time): Duration of the current trip.
- CLK (Clock): Current time.
4.3. Starting and Stopping a Ride
The computer automatically starts recording when it detects wheel rotation and stops when stationary. To reset trip data (DST, AVS, MXS, TM), hold the SET button while in any trip-related display mode.
5. Maintenance
5.1. Cleaning
Wipe the computer unit and sensor with a soft, damp cloth. Do not use abrasive cleaners or solvents, as these can damage the display or casing. Ensure the units are dry before storage or use.
5.2. Battery Replacement
When the display becomes dim or erratic, it's time to replace the battery. Follow the instructions in Section 3.1. Remember to replace batteries in both the computer unit and the speed sensor. After replacing the computer unit battery, you may need to re-enter initial settings (wheel size, time, units).
6. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No display / Dim display | Dead battery; Poor battery contact | Replace battery; Ensure battery is correctly seated. |
| No speed reading / Incorrect speed | Sensor/magnet misalignment; Dead sensor battery; Incorrect wheel size setting; Interference | Adjust sensor/magnet gap (3-5mm); Replace sensor battery; Verify wheel size setting; Move away from strong electromagnetic sources. |
| Computer not responding to buttons | Temporary software glitch | Remove and reinsert the computer battery to perform a soft reset. |
