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, a service message ap-
pears in your display. To inves-
tigate the service message, fol-
low the instructions in "Trouble-
shooting Service Conditions,"
later in this section.
To replace your system's bat-
tery, call your service represen-
tative.
