1. Wake TRACKR SPEED for first use
The TRACKR SPEED ships ready to use with a preinstalled battery.
To wake the sensor for first use, spinning the wheel of the bicycle will activate the accelerometer of the TRACKR SPEED. Once the sensor is awake, the blue LED will blink slowly and will flash quickly before going solid once the sensor is successfully paired to an app or device. LED operation shuts off 30 seconds after waking to conserve battery.
2. Mount the TRACKR SPEED to a bicycle
The TRACKR SPEED ships fully assembled and ready to mount on the hub of your front or rear wheel depending on your preference.
While holding the sensor pod portion of the mount in place on your selected hub, gently stretch the strap portion of the rubber strap around the hub to secure it around bottom two hooks on the mount.
4. Pair TRACKR SPEED to Wahoo app to update firmware and to set wheel circumference
Check the TRACKR SPEED for firmware updates using the Wahoo app [iOS | Android] and to set the TRACKR SPEED's wheel circumference setting to match your bicycle.

Please note that that customizing wheel circumference in the Wahoo app only applies to the Wahoo app. This is not a persistent setting across controlling/recording devices, each device will need to be set separately.
