5.3.3 Battery menu
This menu gives you a summary of the state of any
batteries present. In the patient menu, select the Battery
menu item using the dial:
• Internal battery: always present and supplies the device
with power in an emergency.
• Replaceable battery: available as an option and allows
mobile use of the device independent of an electricity
supply.
• The accuracy of the display depends on the load on the
device (load due to patient breathing, current
operating temperature). The display is continuously
updated.

switched off and during operation.
