PILOT
Via the “ PILOT ” menu, you can activate or deactivate the
pilot tone transmisssion.
The pilot tone supports the receiver’s squelch function
(Squelch) and protects against interference due to RF
signals from other units. The transmitter adds an inaudible
signal, known as the pilot tone, to the transmitted signal.
The receiver detects and evaluates the pilot tone.
Transmitters of the ew 500 series (first generation) do not
transmit a pilot tone and the receivers of the ew 500 series
(first generation) cannot evaluate the pilot tone.
Nevertheless, you can combine the transmitter with a
receiver of the first generation by observing the following:
y With the ew 500 G2 transmitter and an ew 500 G2
receiver:
Activate the pilot tone function with both transmitter
and receiver.

or vice versa:
Deactivate the pilot tone function with the ew 500 G2
transmitter or receiver.
