This chapter describes how to use the various hardware features of
Altair. Describing the software user interface and particular button
assignments in Altair is beyond the scope of this document; these
are described in detail in the XCSoar User's Manual.
All mode and selection buttons are customisable. You may change
the layout of onscreen menus, assignment of buttons to hot-key
functions etc. Refer to the XCSoar Advanced Configuration Guide
for more details.
The LED light indicates the system status as follows:
When the device is switched off, the LED is dark.
When the device is booting and the screen is blank, the LED
is lit.
When the device is running normally, the LED is dark.
The power switch has multiple functions depending on how long
it is pressed:
If the device is switched off, press the button for about one
second to turn it on. The LED will light up and the screen
will remain blank for a few seconds while the computer
starts up.
Hold button down for three seconds to turn the device off.
The screen will go blank immediately.
While the system is running, a short press functions as an
Escape key or Cancel key.
Note: do not turn the device off while XCSoar is initialising (that
is, while the large XCSoar logo is displayed).
When used with Vega, several airframe switches or pilot-operated
switches can be programmed as general purpose buttons in Altair.
