7.1 What do the power meter lights mean?
When you wake up the power meter, the light should turn red, green, and blue in sequence, then pause,
then flash red 1 to 5 times to indicate the battery level.
7.2 Troubleshoot Bluetooth and ANT+ connections
1. Make sure your power meter is awake by spinning the crank several times.
2. Check the battery level using the startup light sequence or 4iiii app.
3. Remove the power meter from the sensor list, and re-pair it.
4. For Bluetooth: Ensure that the power meter is not connected to any other device or app via Bluetooth.
Sensors can only be paired to one device at a time.
