Replacing the Cadence Sensor Battery

The device uses one CR2032 battery. The LED flashes red to indicate a low battery level after two revolutions.

On the back of the sensor, push out the lever and use the tab to rotate the cover counter-clockwise until the marker points to unlocked .

NOTE: Some models do not have the lever and tab on the back of the sensor. You still have to rotate the battery cover counter-clockwise.
Remove the cover and the battery.
Wait 30 seconds.
Insert the new battery into the cover, observing polarity.

NOTE: Do not damage or lose the O-ring gasket.
Align the cover so the marker points to unlocked.

NOTE: The cover must be flush with the case of the sensor.
Rotate the cover clockwise until the marker points to locked.

The LED flashes red and green for a few seconds after battery replacement. When the LED flashes green and then stops flashing, the device is active and ready to send data.
