Pairing with Sportiiiis:
1. Move at least 30ft from any ANT+ sensors you do not wish to pair with Sportiiiis. 2. Spin the crank and rear wheel to active the Bike sensor. 3. Tap and hold the Sportiiiis multi-‐function button until you hear three beeps
and then let go. 4. You will hear an audible confirmation when the Bike Sensor is found.
Calibrating the Speed Sensor: For accurate speed measurements it is necessary to enter your wheel circumference into the Sportiiiis Configuration Utility. Go to Setup > Sensors:
Note: If not readily available, there are many online resources to help determine the circumference of your wheel. Here are two popular sites.

Maintenance for your Bike Sensor: Replacing the Battery – Use a coin to remove the cover on the back side of the Speed Sensor to reveal the battery (CR2032). Be careful not to damage the rubber seal when reassembling. The 4iiii Bike Sensor is waterproof and can be cleaned as necessary.
