How to Test the Battery

Your system may include a

backup battery. If it does, the

system will continue to function

during a power failure, because

it will draw power from the bat-

tery.

You can test the charge in your

system's battery by following

the procedure to the right.

If your backup battery's charge

is low, the TROUBLE icon

lights. To investigate the ser-

vice message, follow the in-

structions in "Troubleshooting

Service Conditions," later in this

section.

To replace your system's bat-

tery, call your service represen-

tative.

To Test the Battery:

1. Press and hold the

[walk test] key for 2 seconds

until you hear 2 beeps.

When prompted, enter the

master user code.

2. Press the

key four

times. You see:

--5

3. Press the key. The

keypad beeps three times.

The battery test begins. The

test takes approximately 2

minutes. If the battery's

charge is low, the keypad's

TROUBLE icon lights.

To replace your system's bat-

tery, call your service repre-

sentative.
