Any time Libris is placed in the Charger, it will enter Sleep Mode cycles for approximately one hour. During this time, the cellular signal strength indicator light will turn off or flash red. Libris will automatically exit Sleep Mode if the Call Button is pressed, the device is removed from the Charger, or it is between Sleep Mode cycles.
Important: Libris requires an adequate cellular signal to function properly. Check with your response team for known coverage limitations.
