What to do if I see a low battery message on my Honeywell LYNXR Security System?

If you see a "Low Bat" message on your Honeywell Security System keypad, with or without zone numbers, it indicates a low battery. If no zone numbers are displayed, replace the system battery. If "Low Bat" is displayed with "00", replace the battery in the remote RF keypad. If "Low Bat" is shown with a zone number, such as "nn", replace the battery in the transmitter for that specific zone.
