Why might I keep getting a message that states "Pairing Failed"?

Verify you are either scanning or entering in the correct pairing code. If you cannot get the unit to Pair via Bluetooth force close the app. IF YOU ARE USING iCloud YOU MUST ALSO TURN ON Apple Key Chain in your Settings. Then swipe away the Onelink Home App and start again after the pushing the alarm test button 5 times to reset the alarm. Retry the pairing process now from the beginning.
