  1. Press Mode to access the Main Menu
  2. Select Settings
  3. Select General
  4. Select Accessories
  5. Select Cadence Sensor
  6. Press the Reset button on your GSC 10 (the white button)
  7. Wait for the Reset button to flash red/green
  8. Select Yes under Cadence Sensor
  9. Select Restart Scan to rescan for your device
  10. Pedal your bike to see alternating red/green blinks on the GSC 10 reset button

The speed/cadence icon will show unblinking on the main menu when pairing is successful.
