26.4.3 Battery-related Alarms
When the battery level is low, the monitor presents the Low Battery alarm, the alarm lamp flashes, and the
monitor produces an alarm sound.
If the battery is almost depleted, the monitor presents the
Critically Low Battery alarm. In this case,
immediately connect the AC mains to power the monitor and charge the battery. Otherwise, the monitor will
automatically shut down soon.
For more information on battery-related alarms, see
DAlarm Messages.

26.6 Maintaining the Battery
26.6.1 Conditioning the Battery
The performance of batteries deteriorates over time. You should condition the batteries periodically or when
you notice a degradation in performance.If the battery is not conditioned for a prolonged time, its charge
indication may not be accurate and you may wrongly evaluate the remaining battery runtime.
To condition a battery, follow this procedure:
1. Disconnect the monitor from the patient and stop all monitoring and measuring procedures.
2. Allow the battery to be charged uninterruptedly till it is fully charged.
3. Allow the monitor to run on the battery until the battery is completely depleted and the monitor automat-
ically shuts down.
4. Fully charge the battery again for use or charge it to 40 - 60% for storage.
NOTE
Do not use the monitor to monitor a patient during battery conditioning.
Interrupting battery conditioning to use the monitor will prevent completion of the conditioning
cycle and require repeating the conditioning process completely to properly condition the battery.
26.6.2 Checking Battery Performance
The performance of a rechargeable battery deteriorates over time. You should check the battery performance
periodically or if you are concerned that the battery may fail.
See steps 1 to 3 of
26.6.1Conditioning the Battery to check battery performance. The operating time of the
batteries reflects their performance directly. If the operating time of a battery is noticeably shorter than that
stated in the specifications, the battery may have reached its service life or be malfunctioning. If the battery
performance meets the requirement, fully charge the battery again for use or charge it to 40 - 60% for storage.
NOTE
Battery operating time depends on equipment configuration and operation. For example, high
display brightness or measuring NIBP repeatedly will shorten the battery operating time.
