Changing settings
A long initial press on the SET button allows the user to make changes
according to the user’s preferences. If you are already using functions on
the SET button you will first have to leave this mode by pressing ALTI
before accessing the settings menu with a long key press.
The first option is Volume. The
v
and
^
buttons allow the volume to be
set as required. This does not effect the headset volume which you can
set internally according to your headset type.
The next option sets the rate at which the vario begins to bleep when
ascending. This is the vario’s UP threshold which is indicated on the
vario’s numerical display in metres/sec plus 0.1m/s for each segment
visible in the vario display.
This is followed by the down threshold which is set in the same way.
You may wish to set the down threshold to respond only when you are
descending rapidly as a warning that you are in sinking air.
A fourth key press in the settings menu allows the Damping factor to
be set. This controls how quickly the audio and visual vario indications
respond to height variations. A short response will cause the vario to
respond quickly to any change in height but it may respond too readily
to small changes, particularly wind buffeting the vario. You may prefer a
slower response which will average out small and rapid variations. Once
you are flying the Alti Vario will tend to silence until lift is detected.
