Warning
When replacing the battery, please pay attention to the polarity.
Plug/Unplug the Battery with the AC power removed
Warning
To protect the environment, do not carelessly dispose of wastes or residues such as
the components of the equipment after its lifetime; instead, ask the biomedical
engineering department of the hospital to dispose of them in the designated places
following appropriate procedures.
If the installation or arrangement of the external grounding wire is doubtful, operate the
equipment with internal power. In case the equipment is not to be used for some time,
remove the primary battery if no safety problem is expected to occur.

Effect of lithium ion battery technology applied to the battery
Refer to the following descriptions on the lithium ion battery technology:
Batteries will be discharged if they are not connected to a monitor. This discharge is caused by the
currents required by the circuit integrated with the lithium ion batteries. Owing to the nature of lithium
batteries themselves, the batteries are self-discharged. The rate of self-discharge is doubled every
time the temperature is increased by 10
℃
(18
℉
).
The loss of electric capacity retained by a battery is higher when the temperature of the battery is
higher. Over the lifetime of a battery, the capacity of a completely charged battery will gradually
decrease, or the battery may not be charged at all. As a result, the total capacity that can be stored
and used will gradually decrease.
Inspection guideline
Check the performance of the battery every 6 months through complete charge and complete
discharge in the monitoring equipment.
Storage guidelines
The battery should be stored at 20°C ~ 25°C (68°F ~ 77°F) when it is not in the monitor. When the
battery is installed in the equipment and connected to AC power, the temperature of the battery is
increased by around 15°C ~ 20°C (59°F ~ 68°F). This shortens the lifetime of the battery.
When installed in the equipment and connected to AC power, the battery does not supply power in
general. The lifetime of the battery may be shorter than 12 months. Bionet recommends detaching the
battery from the monitor for storage until the equipment is moved.
