to hear his vario beep... beep... sound, it is only at this point the green pilot hears the first
beep from his instrument.
The green pilot may have missed the thermal completely had he found the inner zone or if
he was not watching his friend with the VARIO.
6.5.5 Auto Silent
Setting Auto silent on will keep the VARIO's buzzer quiet until a “start flight” has been
detected. A start flight is detected when the instruments detects a altitude variation of 5 m.
The audio will then be kept active until the VARIO is switched off. The default value for the
auto silent parameter is “On”.
6.5.6 Integration
The Integrated vario is calculated by integrating the vertical speed during a period of X
seconds defined by this value. In the example of Figure. 14 the integration period is 10
seconds (default value).
6.6 Screen
The screen menu option allows the user to set the screen contrast. Contrast may be
adjusted to the pilot's needs. Beware of adjusting a very low value may cause the display
to be totally blank. With a blank screen it is difficult to readjust since nothing is visible.
You can use the UP, and DOWN keys, to move the contrast bar (see Figure. 17). Move the
bar to the right to increase the contrast, and to the left to decrease the contrast. When in
the desired position push the ENTER key to confirm the value.
