If you are having trouble with your SimpliSafe security system, quite often problems can be cleared with a Base Station reboot. Simply unplug the power cord to your Base Station and, while unplugged, remove a battery (you'll need a screwdriver to get to the battery compartment). Wait a few seconds, and then put the battery back in and plug in the power cord - the Base Station will then come back on. If you continue to have trouble, please call us at 800-548-9508, we are happy to help.
