The procedure for powering on/off your beacon or getting your beacon into configurable mode varies by the beacon model type. Follow the instructions as described below.
Configurable mode can be re-initiated for RadBeacon USB beacons by removing and restoring power to the device. When a USB beacon is plugged into a power-source, it stays in configurable mode for 30 minutes. After 30 minutes, it will no longer be in configurable mode unless you unplug it and plug it back in.
To turn your USB beacon on, simply plug it into a power-source.
