REPLACING THE CONSOLE’S BATTERY

The console’s backup battery allows the system to work during a power out- age. A 9-volt alkaline battery provides at least 12 hours of backup. BATTERY LOW 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.
