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. The voice message "LOW
BATTERY" will sound once every fifteen minutes during the
chirp only cycle, and will continue for at least seven days.
If the red LED light flashes along with a chirp every 30
seconds, and is not followed by the voice message
"LOW BATTERY" as described above, your unit has
malfunctioned. Call our toll free Consumer Hotline at 1-
800-880-6788 for instructions on how to return the unit.
