SC audio mode has four modes:
 SC positive: sound is interrupted with silence every few milliseconds when the needle
is positive; on negative side sound is linear (not interrupted).
 SC negative: inverse function to SC positive.
 SC: sound is linear and non-interrupted in full scale range.
 SC Mixed: for positive relative values the sound represents relative; for negative
relative values the sound represents SC (for that setting it is recommended to set SC
needle to relative).
 Netto speed: variometer will produce exactly the same sound as defined in Vario
audio, except it will follow netto vertical speed.
Freq at 0% defines the tone frequency at 0 m/s.
Freq at +100% defines the tone frequency at full + deflection.
Freq at -100% defines the tone frequency at full – deflection.
6.1.7.2 Voice*
Voice module is integrated part of V5, V9 or V80 variometer. The voice module is 100%
controlled through the main display unit via the settings described in this menu.
In the Voice menu volume level (loudness) of the voice module can be adjusted. In the
Messages window each item can be set separately. Only checked items will be played by
the voice module.
Volume level (loudness) can be also set with volume rotary knob, when messages
are being played
6.1.7.3 Alarms*
The vario unit produces an audio alarm on reaching certain confirmation points. This screen
allows the parameters of the audio to be configured. If a particular message item is
checked the main display unit will generate an alarm at the time of event.
