2.3 Audio
The volume can be quickly adjusted in flight by the Acoustic-
Function-Button. A brief push shifts from "loud" to "quiet"
and further on to "off".
The present state of the acoustic is shown in the corresponding
display.
2.3.1 Volume levels
"loud" and "quiet" volume each have 6 programmable volume
levels: Adjust "quiet" volume (respectively "loud" volume) in
the main menu to your personal taste on a scale from
"1" to "6".
Hint: Hold Acoustic-Function-Button pushed to enter the "Fast
Setting" mode.
2.3.2 Descent-Tone Threshold
The threshold of the descent-tone can be adjusted within the
adjustment menu from "0" to "9.9" m/s, according to personal
taste. E.g.: If adjusted to 1,5 m/s the sound sets in beyond a
descent-rate of 1,5 m/s while it remains quiet between 0 and
1,5 m/s. Most pilots prefer a set-up between 3 and 4 m/s, more
than the average descent-rate in turns.
2.3.3 Time Interval (interval between 2 climbing beeps)
Some pilots prefer in weak thermal conditions really wide
intervals between the beeps, while others prefer a perpetual
acoustic indication.
Hint: Set profile 1 and 2 to identical acoustic modes, but the
first profile with wide (1) the other with short (9) intervals.
Change profiles in flight to find out your personal preference.
2.3.4 Response-Sensitivity
This is the most important audio adjustment option. Usually
you do not want your variometer to react too sensitively to
brief, narrow bands of lift.
A practical value will be about 1 sec delay. This means that if you
are flying at 36 km/h the thermal must have a diameter of at
least 10 m in order to activate the lift audio!
2.3.5 Audio Simulator
The audio simulator gives an expression of your variometer
acoustic during flight (acoustic on). Turn the Rotary-Button and
listen in on the beeptone corresponding to the climbrate (up to
10 m/s).
