When the Scout is armed, and the alarm has been triggered 3 times in a 10 minute period, it enters ‘lost Mode’, and further triggering of the alarm is inhibited for 10 minutes to preserve battery life and tracking/location services. While in "lost mode", if the app is opened, and the Scout is connected, the arm/disarm button will show the text ‘Lost’.
In order to disable "lost mode" your Iphone will need to be in range of the Scout. Clicking the bell icon will change the status from "lost" to "armed", disabling "lost mode". Clicking again will change the status to "disarmed".
