SinktoneF = Basic Tone pitch - Variometer Sink
Tone pitch at starting Sinktone. The Sinktone is continuous and is heard with deeper sound pitch
at increasing sink speed, and is slowly increasing in frequency again when
approaching rising air. The basic tone pitch of sink acoustics may only be set
equally to the basic tone pitch for climb acoustics. The descent tone may be
switched-off by briefly pressing the Sinkalarm key, or also be switched-on
again; the analog Vario scale display would then show the relevant starting
point. The precise actuation point at which sink rate the sink tone shall start
is adjusted in Main Setup Menu
Sinktone Threshold.
Damp = Dampening of Tone alteration
The Variometer value is recalculated every 0.2s. In case of rapid Vario alterations and setting for
quick tone pitch-increase, it may result between two calculations in a quite intense variation of tone
frequency. The ear perceives this incidence as a kind of fast „piano effect". In order to diminish this
effect, a dampening feature is fitted. For very rapid tone pitch alterations the frequency alteration is
honed. As a result, the Variometer sound is then smoother.
