External DC Power
This external DC power icon is displayed in the taskbar when
the unit is using external DC power and the backup battery is
not present.
Onscreen LEDs (8530 G2 Only)
When the 8530 G2 keyboard is removed, two onscreen-LEDs are
displayed in the taskbar. The left LED acts as the API indicator, and
the right LED acts as the TX/RX (transmit and receive) indicator.
These onscreen LEDs behave in the same way as those on the key-
board, changing colour to indicate different operations. For details
about LED behaviour, refer to “RX/TX – Radio Traffic LED” and
“API – User Application LED” on page 33.
