If the battery is almost depleted, the monitor presents the
Critically Low Battery
alarm. In this case,
immediately connect the external the monitor and charge the battery. Otherwise, the monitor will
automatically shut down soon.
If the battery has been used for a prolonged period of time, the battery will be aged and its runtime may be
significantly less than the specification. If the battery is aged, the
Battery Service Required
alarm is presented
each time the monitor is turned on, indicating that the battery reaches its lifetime.

Charging the Battery
To optimize performance, a fully (or nearly fully) discharged battery should be charged as soon as possible. The
battery can be charged in any of the following methods:
■
Method 1: the monitor is connected to the AC adapter or Dock.
■
Method 2: the monitor is in use with the host monitor.
■
Method 3: the monitor is in use with the Transport Dock.
For method 1 and method 3, the battery is charged in regardless of whether or not the monitor is currently
turned on.

Maintaining the Battery
20.6.1
Conditioning the Battery
The performance of the battery deteriorates over time. You should condition the battery every two months.
To condition a battery, follow this procedure:
1.
Disconnect the monitor from the patient and stop all monitoring and measuring procedures.
2.
Turn off the monitor, and connect the monitor to the external power source.
3.
Allow the battery to be charged uninterruptedly till it is fully charged.
4.
Disconnect the monitor from the external power source, and turn on the monitor.
5.
Allow the monitor to run on the battery until the battery is completely depleted and the monitor automat-
ically shuts down.
6.
Fully charge the battery again for use or charge it to 40 – 60% for storage.
NOTE
•
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.
•
Do not use the monitor to monitor the patient during battery conditioning.
•
Do not interrupt battery conditioning.
20.6.2
Checking Battery Performance
Life expectancy of a battery depends on how frequent and how long it is used. When properly used, the lithium-
ion battery has a useful life of approximately two years. If improperly used, its life expectancy can be shorten. We
recommend replacing lithium-ion battery every two years.
The performance of a rechargeable battery deteriorates over time. You should check the battery performance
every two months or if you doubt that the battery may fail.
