Volume can be also adjusted directly with rotary knob in main menu.
Vario waveform
In this setting user can change the form of audio signal. There are three oprions:
Pure sine shape of signal, triangular or harmonic (sum of more Sine waves).
Vario Audio mode
Vario audio mode has the following options:
• Linear positive: sound is interrupted with silence every few milliseconds when the
needle is positive; on negative side sound is linear (not interrupted).
• Linear negative: inverse function to Linear positive.
• Linear: sound is linear and non-interrupted in full scale range.
• Digital positive: similar to Linear positive, except frequency is not changing linearly
but with larger steps.
• Digital negative: inverse function to Digital positive.
• Linear positive only: sound is present only at positive values, for negative values there
is silence.
• Digital positive only: similar function to Linear positive only, except the sound is
similar to the digital tone.
SC Audio mode
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). Dead band is active only for negative values.
• SC Netto: Sound follows netto value.
Audio frequencies
• 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.
Equalization preset
We have three options: default LXNAV speaker, flat setting or user defined.
Flarm Volume
With Flarm volume slider the volume of flarm warning beeps can be changed.
Volume can be also adjusted directly with rotary knob in main menu but only at
the moment that the Flarm alarm is active.
