The Battery Status
The battery icon indicates the status of your batteries.

of the touch screen. You can still operate your Devices, but you cannot adjust
the settings, enter codes, learn commands or record macros anymore. When
you try to perform these actions, a message screen appears.
Replace the batteries to make the Avidea Remote fully functional again. See
‘The Batteries’ on p. 3 to replace the batteries.
