Error Messages
When switching on the ALVA Satellite the Braille display tests
whether various components of the internal hardware are working
correctly. When the ALVA Satellite tests successfully, the following
message is shown on the Braille display:
ALVA Satellite OK, waiting for connection…
This message disappears when a screen reader is loaded.
Various error messages can be presented on the Braille display.
Pressing any key on the Braille display clears the error message and
the ALVA Satellite may start depending on the nature of the
message. These messages should never occur when the ALVA
Satellite is properly functioning. Always consult your distributor when
one of the following messages appears more than once:
Net voltage out of range
This indicates that there is a problem with the build-in power supply.
USB controller supply voltage out of range
The voltage of the USB controller cannot be set correctly, which
indicates that the USB controller is not working properly.
