Sigma BC-800 user manual

To connect to Sigma BC-800, follow these steps:
1. Install the batteries: Open the battery cover on the back of the device. Insert two CR2032 batteries (ensure correct polarity) and close the cover securely.
2. Mount the Sigma BC-800 on your bike: Determine the appropriate position on your bike's handlebar or stem to mount the device. Use the included cable ties or mounting bracket to attach the Sigma BC-800 securely to the chosen location.
3. Set the wheel size: The wheel size needs to be set on the device to accurately measure speed and distance. Refer to the instruction manual to find the appropriate wheel size for your specific bike. To set the wheel size, press and hold the "SET" button until the display shows "Wheel Size" followed by a flashing number. Use the "MODE" button to adjust the number to match your wheel size, then press "SET" to confirm.
4. Pair the sensor: The Sigma BC-800 may have a separate sensor unit that needs to be attached. Follow the manufacturer's instructions to mount the sensor on the front fork or rear chainstay of your bike. Ensure the distance between the sensor and magnet is within the recommended range (usually a few millimeters). Align the magnet with the sensor, so they are in close proximity, without touching.
5. Activate the Sigma BC-800: Once the sensor is mounted correctly, the Sigma BC-800 should be automatically activated when the wheel starts to turn. Verify that the display shows speed, distance, or any other relevant data to confirm proper activation.
Congratulations! You are now connected to Sigma BC-800 and ready to track your cycling data.
