2 SYSTEM FUNCTIONS

2 System functions

This section 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.

2.1 Power switch

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.

• When the device is powered by the backup battery, the LED is blinking.

The power switch has multiple functions depending on when and how long it is pressed:

• If the device is switched off, press the button for about half a 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 approx. 1 second to turn the device off.

• While the system is running, a short press functions as an Escape key or Cancel key.

Do not turn the device off while XCSoar is initialising (that is, while the large XCSoar logo is

displayed).

2.2 External switches

A control grip stick is available from triadis engineering GmbH .

This is an optional feature and not necessary for the devices to

work normally. Contact your Altair/Vega dealer for details.
