UNDERSTANDING SENSOR FIRMWARE UPDATES

AXS firmware updates are periodically released for every AXS component to improve general system performance and function. Each AXS component must be individually checked for updates.

UPDATING SENSOR FIRMWARE

1) Open the AXS App. Ensure Bluetooth is enabled on your mobile device and has a cellular or Wi-Fi connection.

2) Wake the sensor(s) by spinning or rotating them or lightly bouncing your bicycle.

Getting stuck? Install a new coin cell battery if a sensor does not wake from movement. Then, try again.

3) Select Connect to continue.

Getting stuck? If a component does not connect, ensure it's awake and your mobile device's Bluetooth is enabled. Then try again. If this doesn't work, force quit the AXS App and toggle your mobile device Bluetooth off and on. Then, try again.

4) Select the component to enter its part menu.

5) Select New Firmware Available. If the firmware is already up to date, no action is needed. Exit the part menu.

6) Select Install to continue.

7) The firmware update will begin automatically, and the component's LED will blink during installation. Do not exit the firmware update screen or AXS app during installation.

Getting stuck? If the update does not start or progress, return to the Bike Profile page (step 4), and attempt again. If this doesn't work, force quit the AXS App and toggle your mobile device Bluetooth off and on. Then, try again.

8) Select Continue to exit the firmware update menu after installation.
