The RPM uses a Blue and Red LED to give instant feedback to the user during the pairing process. These LEDs operate for about 30 seconds before shutting off to conserve battery. The Red LED flashes for 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.
*LED indicators are the same for the RPM Cadence, RPM Speed, and BLUE SC sensors
