10.1. Advanced settings
FREQ - The audio frequencies can be adjusted to match the user's
preference, by setting the Base Frq and Increments.
The Base Frq is the first frequency used to produce the initial sound which
corresponds to the climb threshold (by default 0.1 m/s). Later, as the
climb rate increases, a bip, bip sound is produced for which the cadence,
and frequency, also increase. The Base Frq can be set from 500 to 1500
Hz. The higher is the frequency value, the higher pitched the sound is. The
preset value for Base Frq is 700 Hz.
INCR - The Increments parameter sets the frequency increment for each
0.1 m/s climb rate increase. The increments can be set from 1 to 99 Hz.
The preset value for Increments is 10 Hz. Considering an Increments
value of 10, and Base Frq of 700 Hz, the vario frequency at 1 m/s is 800
Hz.
DAMP - The Vario LS vertical speed calculation is based on air pressure
variations. It is very seldom to have air pressure absolutely stable.
Turbulence caused by air moving near the sensor is suficient to cause
small variations in pressure. For this reason the Vario LS filters (averages)
the pressure data to prevent constantly detecting tiny pressure variations.
The value that defines how must the pressure is filtered is the Damper.
Setting a lower damper value caused the Vario LS to become more
responsive but harsher. Inversely a higher value causes the Vario LS to be
less responsive but smoother. The default value is 8.
CADE - When a rate of climb is higher than that specified by the Climb
threshold the Vario LS creates a beeping sound. The rate (cadence) of the
beeps increases as the climb rate increases. This increase in rate is not
linear. The cadence parameter species which cadence curve should be
used.
