Caution:
Should a low battery alarm sound, connect the monitoring system to an AC
power source and then silence the alarm by pressing ALARM SILENCE. If the
monitoring system is operated on an AC power source with a depleted
battery and AC power is subsequently lost, the monitoring system will shut
down immediately.
The monitoring system runs on an internal battery when not connected to an
AC power source. A battery fuel gauge displays the remaining battery power.
When connected to AC power, the battery fuel gauge displays a lightning bolt
while charging and at full charge.

Note:
As the battery is used and recharged over time, the amount of time between the onset
of low battery alarms and the monitoring system shut-off may become shorter.
