lights on the console when you
need to replace the backup battery, but
you should replace the battery at least
once a year.
Do not unplug the console from AC
power when you replace the battery.
Otherwise, the console loses all mem-
ory of the installed wireless sensor
transmitters, motion detectors and re-
mote controls, and the voice message
and stored numbers. You must then
set the
INSTALL/RUN 1/RUN 2 switch on
the console to
INSTALL, re-record your
emergency message, re-program
emergency numbers, and then re-in-
stall all the wireless sensor transmit-
ters, motion detectors and remote
controls.
REPLACING A
REMOTE’S BATTERIES
If the console does not respond to a re-
mote control’s signal, replace the bat-
teries in the remote control’s battery
compartment, according to the polarity
symbols (+ and –) marked inside the
compartment.
After you replace the remote control’s
batteries, re-initialize the remote con-
trol as described in “Installing the Key-
chain Remote Control” on page 11 or
“Installing the Handheld Remote Con-
trol” on page 12.
Note:
When you press a button on the
keychain remote, BATTERY lights to
show the battery is good.
After replacing batteries, follow these
steps to confirm that the console still
recognizes the remote control.
1. Set
INSTALL/RUN 1/RUN 2 on the
console to
RUN 2.
2. Press
ARM on the remote control.
If the system arms, the console recog-
nized the remote control.
If the system did not arm:
1. Set
INSTALL/RUN 1/RUN 2 to
INSTALL.
2. Press
ARM on the remote control.
The remote control transmits a
random code to the console. The
console acknowledges this with a
chime and logs in the remote con-
trol. If you do not hear a chime,
press
CODE with a pencil and then
press
ARM.
