1.5 Resetting the VARIO SD
The reset procedure allows the pilot to restart the VARIO SD in the unlikely event that it freezes, or stops
responding (if this ever occur please report it to our support email). To reset the VARIO SD push S1
(Menu) key and the S4 (Down arrow) key, simultaneously, for at least two seconds. The display will go
blank and after will return in Flight mode.
1.6 Setting the Volume
The VARIO SD sound volume can be adjust using one FS Key, or trough the Vario Accoustics option of
the Settings Menu (see Section
4.4
). The VARIO SD has six dierent sound levels, plus no sound. The
current volume level can be seen using the sound element (see Section
3.1.2
for more details).
Pressing the dened FS Key will scroll up the sound level until the maximum value. Pressing more will
mute the sound before start scrolling again starting from the minimum value.
Note: Changing the volume using an FS key is only valid for the current ight, and will not
override the volume level setting. Every time the instrument is turned on, if the sound is
muted, an alarm is generated in order to notify the pilot.
1.7 Flight Start and Recording
Most of the VARIO SD features are only available after the Flight Start. This procedure is taken in
order to avoid wrong calculations due to missing data. Flight starts when average vario is greater than
+-0.15m/s
