The radar device disconnects from the Varia RDU device
If the radar device is not connected or sending radar data, Garmin® recommends that you stop riding and check the devices in a safe location. Failure to do so could result in serious injury or death.
If the threat level LED is solid red and the REAR LED is off, the radar device is not connected to the Varia™ RDU device.
Turn both devices off, and turn them back on.
You can check the battery level when you turn the devices back on.
- Pair the devices (Pairing the Radar Device with the RDU Device).
