The optional Barometric Pressure Unit (
SU-1
) brings
to the
VXA-200
the unique capability of providing
readout of the current barometric pressure. This in-
formation is the used for calculation of your cur-
rent altitude, and also used for calculation of your
current density Altitude using with the temperature
sensor.
The Barometric Pressure unit and temperature sen-
sor requires calibration of the “offset” parameters,
so that differences in pressure can be used to calcu-
late altitude. This procedure requires that you have a
calibrated barometer, calibrated thermometer, and
that you know your current altitude. If you are at sea
level, of course, the latter parameter requires no re-
search.
Beep On/Off
The
VXA-200
’s key/button beeper provides conve-
nient audible feedback whenever a button is pressed.
Each key and button has a different beep pitch, and
each function has a unique beep combination.
When you are scanning, the beeper will be heard each
time the scanner halts on a busy channel. This may
be distracting in some environments; if you want to
