Each Gen 3 Stages power meter has an LED indicator located in the center of the power meter housing that indicates the status of the power meter. Note: Gen 1 and Gen 2 Stages Power meters do not have the LED indicator light on the power meter housing. 

At startup, the power meter's LED light will blink based on the battery level: Green (6-100%) or red (1-5%) flash to indicate battery level every second for the first 12 seconds after startup. When using a magnet sensor, the LED light will blink blue after it has successfully detected the presence of a cadence magnet.
