4 Vega U2020 UHF
Receiver Front Panel Controls and Indicators
Power Switch: The
receiver is “on” when the
switch is to the right.
Audio Level : Indicates relative audio level.
Should flash in the green zone occasionally.
Readings in the yellow zone indicates audio is
very high (in full deviation). Readings in the red
zone indicate the level is too high.
RF Signal Strength : Shows channel’s
RF level. Should read well up into the
green zone . Occasional dips into the
lower green area are ok, but consistent
readings there indicate you should take
steps to improve the signal. A reading in
the yellow zone indicates a very low
signal level. Readings in the red zone
indicate poor audio quality and loss of
the signal is likely. When the signal is
absent or below the useful range, the
RF level and audio indicators will go
“off” and the output will be squelched.
Channel Select Indictors:
Shows which channel the
receiver is operating on.
Channel Select Switches: Use
a small screwdriver to select the
desired frequency (must be the
same as the transmitter
Diversity Indicator: LEDs show which channel
is being used. In diversity mode, the LEDs
probably will switch back and forth, though at
short ranges, one LED might stay on
continuously (RF level is above the range
where diversity switching is useful). When the
receiver is squelched, one indicator will stay on.
Channel “A” antenna
mount: for mounting
antennas in front of the
receiver.
Channel “B” antenna
mount: for mounting
antennas in front of the
receiver.
