10. VARIO
The CORE vario offers a number of options for ne-tuning the sound output relating to your model’s climb and
sink.
a) Sensor
The vario must be connected to a bound receiver,
and must be visible in the Sensor List; a brief press
on the Sensor button displays all the available sen-
sors. At this point you should select the value for
rate of climb for your sensor.
b) Vario On / Off
At this point you can choose a transmitter control
which switches the vario tone on and off.
c) Start tone
Here you determine the basic frequency of the tone output when the vario is generating 0 m/s.
d) Climb sensitivity
At this point you can dene how steeply the tone is to change when the model’s climb rate alters. If you enter
a high value, the vario tone will alter more rapidly, even when the climb rate is small.
e) Sink sensitivity
Here you can dene how steeply the tone is to change when the model’s sink rate alters. If you enter a low
value, the change in vario tone will be less marked, even when the sink rate is high.
f) Climb offset
This value determines the threshold for climb at which the vario is required to generate a tone. In weak thermal
conditions you would probably set this to a low value to enable you to detect even small areas of lift acousti-
cally. The ltering of the vario sensor also plays a role here. If you place the vario on a stationary surface and
it uctuates by 0.2m/s to 0.3m/s, then it makes sense to set this value slightly higher. Varios with good digital
ltering such as the PowerBox PBS-Vario allow low values here.
g) Here the same applies as for f), but for the Sink range.
1. When pressed briey the parameters entered on the left are played back once.
2. If you keep the button pressed, you can change the voice in this menu. First you will see the voices which are
available for your set language. Pressing on the globe at bottom right displays all the voices together with the
associated language. This enables you, for example, to have English expressions spoken using an English
voice, even though the CORE is set to German.
