4.2.10 ACOUSTIC VARIO

The acoustic vario represents the instantaneous values of the vario with a modulated acoustic tone.
 LONG PRESSING the key while on any page (except Info GPS) changes the vario volume (3 settings): “HIGH”,
“OFF” & “LOW”.
The chosen volume is shown by the ‘loudspeaker’ icon on the bottom left side of the display.
Please note that if the SKPW (ADVANCED SETUP \ n. 24 SKPW) parameter is ON, the function of LONG
PRESSING the
“arrow down” button, while flying with an active route will skip to the next waypoint and not
adjust the volume; therefore, make sure you set the volume level before activating the route.
Remember that when you turn your Digifly AIR on, it checks the volume of the acoustic vario and, if it happens to
be turned off, it will immediately turn it up to HIGH.

To set the sound’s threshold level to indicate lift, go to: VARIOMETER SETUP \ n. 1 V.UP; for the sink’s threshold,
go to: VARIOMETER SETUP \ n. 3 V.DN.

It is possible to set the preferred acoustic profile with the VARIOMETER SETUP \ n. 4 PROF parameter. Three
pre-set profiles are available (FAS, STD, SFT) plus two fully customizable ones (USR1, USR2 - using AirTools);
moreover, there is a manual ‘MAN’ mode, to directly customize the instrument using the following parameters:
o
Style (VARIOMETER SETUP \ n. 5 STYL): the relation between sound/pause; values from 1 to 3.
o
Modulation (VARIOMETER SETUP \ n. 6 MODH): increases the tone frequency; values from 1 to 30.
o
Pitch (VARIOMETER SETUP \ n. 7 PITC): increases the ascending tones’ rhythm; values from 1 to 4.
o
Climb (VARIOMETER SETUP \ n. 8 UPHZ): climb’s threshold tone’s frequency.
o
Sink (VARIOMETER SETUP \ n. 9 DWHZ) sink’s threshold tone’s frequency.

Auto-silence (VARIOMETER SETUP \ n. 21 AUTV): “ON” by default, it activates the acoustic vario only after
takeoff and stops it 60 seconds after landing. (see 4.2.11 for the “FUL” setting).
4.2.11 ACOUSTIC VARIO PRE-THERMAL TONE

If activated, an acoustic signal with a tone and modulation significantly different of the acoustic vario, indicates
that we are near a thermal (the instantaneous sink rate is better of the glider’s minimum sink rate, therefore
indicating an area of slightly climbing air). To set the pre-thermal sound’s threshold go to: VARIOMETER SETUP \
n. 2 V.PT; value from 0,00 to 1,50 m/s and the suggested value is 0,50 m/s.

If the parameter VARIOMETER SETUP \ n. 21 AUTV = FUL means the pre-thermal tone is only activated during
glide and the acoustic vario will activate right after takeoff.
4.2.12 VARIO SIMULATOR

For a perfect tuning of the acoustic vario, without flying, it is possible to set the ‘Vario Simulator’ mode, setting
the VARIOMETER SETUP \ n. 20 SIMV parameter to “ON” and VARIOMETER SETUP \ n. 21 AUTV to “OFF”. Then
exit from menu and use the arrow keys to set the preferred vario sound.
To deactivate the simulator set SIMV to “OFF” and AUTV back to “ON”.
Note
: for safety reasons the simulator is automatically deactivated when the instrument power on.
