Battery Operation
20
Low Battery Indicator
The
Low Battery
Indicator lights and a low priority alarm begins to sound
when 15 minutes but not more than 20 minutes of monitoring time remain
on the existing battery charge. This alarm cannot be silenced while
running on battery power. Connecting the N-560 to AC power will silence
the alarm. If the N-560 is not connected to AC power within
approximately 15 minutes, the N-560 will shut off.
Note: As the battery is used and recharged over a period of time, the
amount of time between the onset of the low battery alarm and the
N-560 shutoff may become shorter.
It is recommended that qualified service personnel replace the internal
battery every 24 months.
CAUTION: If the N-560 is to be stored for
3
months or longer, notify
service personnel to remove the battery from the N-560 prior to
storage. Recharge the battery when it has not been charged for
3
or
more months.
The
Low Battery
Indicator flashes and a high priority alarm begins to
sound when the battery reaches the lowest battery voltage at which an
N-560 can support normal operation. This alarm cannot be silenced while
running on battery power. If the N-560 is not connected to AC power, the
N-560 will shut off after 10 seconds.
