9.1 Overview
The monitor has a built-in rechargeable battery to ensure that the monitor can also be used normally
in case of patient transfer or power failure. When the monitor is connected to an DC power source, it
will charge the battery no matter whether the monitor is turned on or not. In the case of power failure,
the system will automatically use the battery to power the monitor to avoid interrupting the monitor
working.
The battery icon on the screen indicates the battery status:
Battery is working properly and is fully charged.
Battery is working properly and the green part indicates the battery power.
Battery power is low, and requires charging immediately, or else the pulse
oximeter will turn off automatically.
Battery is not installed.
Battery is properly installed and being charged.
The battery power can only maintain for some time. Low battery voltage will trigger a high level
technical alarm “Battery Low”; in this case, connect the monitor to DC power and charge the battery.
9.2 Battery usage guide
Battery life depends on the frequency and time of use. If the battery maintenance and storage are
proper, the lithium battery life is three years. If you do not use the battery properly, its life may be
shortened. It is recommended to replace the lithium battery once every three years.
In order to ensure the maximum capacity of the battery, please note the following usage guide:
Do not drop the battery.
Check the battery performance once every two years. Before servicing the monitor or you
suspect that the battery is the fault source, also check the battery performance.
