Check your Bluetooth and your phone, and check transmitter is fully charged, or visit start.limborevolution.com for a step-by-step guide.
First, try closing the app and ensure it's not running in the background of your phone. Then turn off your Bluetooth, wait a few moments and turn it back on again. If this doesn't work, try turning your phone off completely and then reconnect your transmitter.
Ensure your transmitter is fully charged before trying to connect. If you are setting up for the first time visit start.limborevolution.com for a tutorial video and step-by-step guide.
