8.1 Overview
The pulse oximeter has a built-in rechargeable battery to ensure that the pulse oximeter can
also be used normally in case of patient transfer or power failure. When the oximeter is
connected to a DC power source, it will charge the battery no matter whether the pulse
oximeter is turned on or not. In the case of power failure, the system will automatically use
the battery to power the pulse oximeter to avoid interrupting the pulse oximeter working.
The battery icon on the screen indicates the battery status:
Battery is working properly and is fully charged.
