LCD Status Display
Pointing mode display
By default, at power up the LCD shows the pointing display. The
top line alternates between “Pointing” and the compass bearing
and elevation angle of the closest satellite. In the picture below,
the satellite bearing is South-Southeast (SSE) and the elevation
angle to the satellite is 46 degrees.
The lower line displays the received signal quality, both
graphically and as a number in tenths of a dB. In pointing mode
typical values are 52.0 to 55.0. The higher dB value that you can
get, the better.
Audible pointing indicator
A buzzer provides an audible representation of the signal quality
during antenna pointing. When turned on, the indicator emits
pointing tones that increase in tempo and pitch as the signal
strength increases. If the satellite is not found, one tone is
followed by a pause. The indicator always defaults to off when
the unit powers on.
Use a long press of the Audio button to toggle the audio pointing
indicator on and off.
