Icon Meaning

Backup battery is low.

Backup battery is very low.

Note that when the charge level in the battery pack gets very low, an exclamation mark (!) appears beside the battery icon. The Aero 2100 will also display a message to alert you. The message recurs periodically until you have replaced the backup battery.
