Onscreen Indicators
Security Level
Security levels can be set to limit user access to 8525/8530 settings. In addition,
applications can be restricted to prevent inadvertent changes.
Battery Icons
Battery In Use
This icon indicates that the 8525/8530 is drawing power from the backup battery
rather than external DC power.
Battery Very Low
When the 8525/8530 is running on the backup battery (rather than external power)
and the battery power is nearly depleted, this icon is displayed in the taskbar.
Battery Charging
This battery icon indicates that the vehicle-mount is running on external DC power,
and that the backup battery is present.
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 Only)
When the 8530 keyboard is removed, two onscreen-LEDs are displayed in the
taskbar. The LED to the left acts as the API indicator, and the LED to the right acts
as the TX/RX (transmit and receive) indicator.
These onscreen LEDs behave in the same way as those on the keyboard, 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 40.
