What to do if I see a low battery message on my ADEMCO LYNXR keypad?

If your ADEMCO Security System keypad displays a low battery message, there are several possible causes. It could be due to a low or missing system battery, in which case you should replace the system battery. Alternatively, the remote RF keypad/button battery might be low, requiring you to replace the battery in the RF keypad. Finally, the transmitter for a specific zone might have a low battery, indicated by 'nn'; replace the battery in the displayed transmitter.
