What are the functions of the RPM Speed/Cadence and Blue SC LEDs?

The RPM Speed/Cadence and Blue SC LEDs provide instant feedback to easily assess functionality. These LEDs operate for 30 seconds before shutting off to conserve battery.


The Red LED indicates cadence detection.

The Blue LED represents your connection state and has three modes:

  • Slow Blink (about once every second) – RPM is awake and not paired.
  • 4x Flash – Occurs the instant a connection is made.
  • Quick Blink (about twice every second) – RPM is paired to a device.
