You can check the status of your KATANA Safety Arc in your KATANA Safety App. From the home screen, if you are not paired, it will say so at the top of the screen. Click the menu button on the top left and select “Arc Paired Info”.

Also, there is a small indicator light on the bottom left of your Arc. It will blink blue every two minutes if you've lost your Bluetooth connection or turned off your location services. It will blink red if you've closed the app or lost paring. Remember to always keep Bluetooth and location services on and the app open in the background on your phone.
