WARNING: Failure to properly charge and maintain the System 1 Base
Batteries can cause the unexpected loss of battery backup function.
WARNING: The Battery Charge Level bar graph and power status indicators
depend on the proper charging and maintenance of the battery system. Failure
to properly charge and maintain the System 1 battery system can cause
battery failures.
CAUTION: Replace the batteries every 2 years, OR whenever the batteries
cannot be fully recharged within 13 hours, OR whenever fully charged batteries
will not power a fully loaded system for 60 minutes.
CAUTION: Do not store batteries in a discharged state as this will damage
them.
Decreasing the power consumption of the system while operating on battery power
can enable the batteries to power the system for more than 1 hour. Turning off non-
critical devices will decrease the power needs of the system.
If the system shuts down due to depletion of battery power, make sure to plug the
system into available wall power and that the system power switch is ON.
Battery System Testing
The batteries are tested at different times during use of the system.
Automatic Testing of Switching to Battery System
Each time the system is powered on, a switching test of the battery system is per-
formed. If the system detects an issue with battery system circuitry at start-up, the
following message will be displayed: "Battery Cannot be Charged - Full Backup May
Not be Available".
If this message is posted, contact Terumo Customer Service. Do not attempt to oper-
ate the system until it has been serviced.
In addition, battery circuit components are monitored constantly during operation. If
a problem is detected, the following message will be displayed: "Battery Cannot be
Charged - Full Backup May Not be Available".
If this message is posted, contact Terumo Customer Service. Do not attempt to oper-
ate the system until it has been serviced.
Manual Testing of Switching to Battery System
To test the battery switching function, unplug the system when it is turned on. If the
system does not immediately switch to battery power, contact Terumo Customer Ser-
vice. Do not attempt to operate the system until it has been serviced.
