Battery Replacement

If any form of battery failure is detected the red LED light will
flash and the unit will "chirp" one time, followed by the
warning message "LOW BATTERY." This cycle will occur
once every minute for the first hour. After the first hour, the
red LED light will continue flashing accompanied by the
chirp only sound every 60 seconds.
