4. Installation Guide
Follow these steps to correctly install your bicycle computer:
- Attach the Base to the Handlebars: Secure the computer's mounting base to your bicycle's handlebars using the provided plastic straps or O-ring.
- Fix the Monitor to the Base: Slide the bicycle computer head unit onto the installed base until it clicks securely into place.
- Attach the Wireless Sensor: Use the plastic straps to attach the wireless sensor to the front fork of your bicycle. Ensure it is positioned correctly to align with the wheel magnet.
- Attach the Speed Magnet: Loosely attach the speed magnet to a spoke on your front wheel.
- Adjust Distances:
- Adjust the distance between the magnet and the sensor to be within 3 mm (ideally less than 1.5 mm).
- Ensure the distance between the wireless sensor and the bicycle computer is less than 60 cm.
- Secure Components: Once distances are correct, tighten the plastic straps for the sensor and magnet. Trim any excess strap material.


5. Initial Setup and Configuration
After installation, you need to configure the computer for accurate readings.
5.1. Battery Activation
Before first use, ensure you remove any insulation sheets from the batteries in both the computer head unit and the wireless sensor. The computer uses 2 x CR2302 button batteries.
5.2. Wheel Circumference Setting
Accurate speed and distance readings depend on correctly setting your wheel's circumference. Refer to your bicycle's tire specifications or measure it manually.

5.3. Language Selection
The computer supports five languages: English, Deutsch, French, Dutch, and Espanol. Follow the on-screen prompts during initial setup or consult the full manual for specific button combinations to change the language.

5.4. KM/H or MPH Switch
You can switch between kilometers per hour (KM/H) and miles per hour (MPH) based on your preference. This setting is usually part of the initial setup or accessible through the settings menu.
5.5. Bike A/B Selection
If you use the computer on two different bicycles, you can configure settings for each. Press the [SET] button for two seconds to select between Bike A or Bike B modes.

6. Operating Instructions
The bicycle computer features two main buttons: [MODE] and [SET].

6.1. Function Display Cycle
Press the [MODE] button to cycle through various functions:
- CLOCK (Current Time)
- ODO (Total Odometer)
- DST (Trip Distance)
- MXS (Maximum Speed)
- AVS (Average Speed)
- TM (Riding Time)
- TEM (Temperature)
- CAL (Calories Burned)
- SCAN (Cycles through functions automatically)

6.2. Backlight Operation
The computer features a green backlight for night visibility.
- Short Light Mode: Each time a button is pressed, the backlight illuminates for 3 seconds.
- Long Light Mode: Press and hold both the left and right buttons simultaneously to keep the backlight on continuously.
To toggle the backlight mode (LIGHT ON/LIGHT OFF), hold [SET] + [MODE] buttons simultaneously. When in LIGHT ON mode, pressing any key will activate the backlight for 6 seconds. When in LIGHT OFF mode, the backlight will remain off.

7. Power Management
7.1. Solar Energy
The integrated solar panel provides emergency charging and extends the life of the internal batteries by converting sunlight into electricity. However, the primary power source remains the button batteries, especially in low light conditions.

7.2. Automatic Wake-up and Power Saving Mode
The computer features an automatic stop-start function. It will enter a sleep mode with only the clock displayed after 4 minutes of inactivity. Once the wheel moves, the computer automatically wakes up and resumes tracking data.


7.3. Low Power Indicator
A low power indicator will alert you when the batteries need to be changed. Your data will not be lost during battery replacement.
8. Maintenance
- Cleaning: Wipe the computer with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Water Exposure: The device is daily waterproof. Avoid submerging it in water or exposing it to heavy rain for prolonged periods.
- Battery Replacement: When the low power indicator appears, replace the CR2302 button batteries. Use a coin to unscrew the back cover for access.

9. Troubleshooting
- No Speed/Distance Reading:
- Check the distance between the speed magnet and the wireless sensor. It must be less than 3 mm.
- Ensure the wireless sensor is within 60 cm of the computer head unit.
- Verify that the batteries in both the computer and sensor are correctly installed and have sufficient charge.
- Display Not Working:
- Check battery levels.
- If the computer is in power-saving mode (only clock displayed), move the wheel to wake it up.
- Data Resetting Unexpectedly:
- Removing the battery will reset all data except the total odometer (ODO).
- Ensure the battery is securely in place.
- Difficulty Resetting Trip Data:
- The computer typically accumulates trip data. To reset trip-specific data (like DST, MXS, AVS, TM), refer to the detailed instructions in the full manual for the specific button combination. Often, this involves holding the [MODE] or [SET] button while on the desired display.
10. User Tips
- Sensor Placement: For optimal performance, mount the wireless sensor on the front wheel fork. The closer the magnet and sensor are, the more reliable the speed detection.
- Battery Life: While solar energy assists, the primary power comes from the button batteries. Always keep spare CR2302 batteries on hand for uninterrupted use.
- Data Management: Understand that trip data (DST, TM, etc.) can usually be reset for each ride, while the total odometer (ODO) is cumulative.
- Backlight Use: Use the short light mode for quick checks to conserve battery, and the long light mode for extended night riding when constant visibility is needed.
11. Warranty and Support
