Step 11:
Check your touchscreen to ensure it no longer displays the “BAT” or “SYSTEM LO BATTERY”
message. If it still shows a low battery message, try entering your code and pressing the OFF button.
Repeat if necessary. If the message still shows, it may take 24 to 48-hours for the battery to fully charge.
If after 48-hours the message still shows, please call (800) ADT-ASAP to troubleshoot your system.
When the message is gone or you’re waiting for the battery to charge, remove your system from Test
Mode at MyADT.com.
Ensure your system is working properly by testing your system. Go to MyADT.com and place your
system on test and then follow the directions in the user guide to test your system or visit MyADT.com
to find your user guide.
