5. Setup and Installation
5.1 Initial Preparation
- Remove all protective films from the bike computer screen and other components.
- Battery Installation: Install the required batteries into the bike computer, transmitter, and heart rate sensor belt. Refer to the small instruction manual for specific battery types and installation directions. A small screwdriver may be needed for some compartments.

5.2 Mounting the Bike Computer
- Attach the Extend Mount to your bicycle handlebars using the provided zip ties. Ensure it is securely fastened and positioned for easy viewing.
- Slide the bike computer main unit onto the extend mount until it clicks into place.

5.3 Installing the Magnet Sensor and Transmitter
- Attach the Transmitter to the bicycle fork using zip ties.
- Attach the Magnet Sensor to a spoke on your front wheel.
- Adjust the position of the magnet sensor and transmitter so that they are aligned and the distance between them is minimal (typically within 5mm) when the wheel rotates. This ensures accurate speed and cadence readings.

5.4 Wearing the Heart Rate Sensor Belt
- Moisten the electrode areas on the back of the heart rate sensor belt with water or electrode gel for better conductivity.
- Strap the belt around your chest, just below your pectoral muscles, ensuring the sensor is centered and snug against your skin.

6. Operation
6.1 Power On/Off
- To Power On: Press and hold the power button (usually labeled 'MODE' or 'SET') for approximately 3 seconds.
- To Power Off: Press and hold the power button again for 3 seconds.
6.2 Mode Selection and Settings
- Change Modes: Short press the 'MODE' button to cycle through different display modes (e.g., speed, distance, time, heart rate, cadence).
- Adjust Settings: Press the 'SET' button to enter settings mode. Use the 'MODE' button to navigate options and 'SET' to confirm selections. Refer to the small instruction manual for detailed setting configurations (e.g., wheel circumference, time, units).
6.3 Backlight Function
- The device features a convenient backlight design for clear data reading in various lighting conditions.
- To activate or change the backlight color (Blue, Green, White), locate the backlight button (often indicated by a lightbulb icon) and press it.


7. Maintenance
- Cleaning: Wipe the bike computer and sensors with a soft, damp cloth. Do not use abrasive cleaners, solvents, or harsh chemicals, as these can damage the device.
- Storage: When not in use, turn off the device and store it in a dry place, away from direct sunlight and extreme temperatures.
- Battery Replacement: Replace batteries as needed. Refer to the small instruction manual for specific battery types and replacement procedures.
- Heart Rate Belt Care: After each use, rinse the heart rate sensor belt with clean water and hang it to dry. Do not machine wash or tumble dry.
8. Troubleshooting
8.1 No Display / Device Not Turning On
- Check if the batteries are correctly installed and have sufficient charge. Replace if necessary.
- Ensure the power button is pressed and held for the required 3 seconds.
8.2 Inaccurate Speed/Distance Readings
- Verify that the magnet sensor and transmitter are correctly aligned and the distance between them is within the recommended range (typically 5mm).
- Check the wheel circumference setting in the device's settings menu. Ensure it matches your bicycle's wheel size.
- Ensure there is no interference from other electronic devices.
8.3 Heart Rate Sensor Not Working / Inaccurate Readings
- Ensure the heart rate sensor belt electrodes are moistened before wearing.
- Check the battery in the heart rate sensor. Replace if low.
- Ensure the belt is worn snugly against your skin, just below the chest.
- If the heart rate sensor or chest strap is damaged (as reported by some users), consider replacing the component. Contact the manufacturer for replacement parts.
9. User Tips
- Heart Rate Sensor Longevity: To extend the life of your heart rate sensor and strap, always rinse it with fresh water after each use to remove sweat and salts, which can corrode the electrodes over time.
- Replacement Parts: If a specific component like the heart rate sensor or chest strap breaks, it may be possible to purchase just the sensor or strap separately. Check with the manufacturer or seller for availability.
- Backlight Usage: Utilize the adjustable backlight feature for optimal visibility in low-light conditions, but remember that continuous use of the backlight can drain battery faster.
