Battery Power Usage

WARNING:
Do not use monitoring system in a depleted battery condition.

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 will operate on battery when not connected to AC
power. Some usage conditions draw more power from the internal battery
than others. Duration of operation depends on the battery charge status.
Avoid power-intensive conditions for ideal battery usage. The following condi-
tions will help achieve the longest battery life:
•
No audible alarms sound
•
No analog or serial output devices are attached to the monitoring system, includ-
ing serial data, analog output, and nurse call output
•
25% monitoring screen brightness setting
Ensure the monitoring system remains connected to an AC power source
when not in use so a fully charged battery remains available for use at any time.
When any of the following conditions are present, the monitoring system
automatically shuts down.
•
The monitoring system is running on battery power and the battery capacity
remaining reaches 0%.
•
The monitoring system has detected an internal temperature above 67 ºC or 153 ºF.
