Psion Teklogix Understanding External DC Power and Onscreen LED Indicators for Teklogix 8530

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.
