PILOT
Via the “PILOT” menu, you can activate or deactivate the
pilo t to ne evaluati on.
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, and is
thus able to identify the signal of the matching transmitter
and mute all others.
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 EK 500 G2 receiver with
a transmitter of the first generation. However, when
combining units, please observe the following:
y With an ew 500 G2 transmitter and the ew 500 G2
receiver:
Activate the pilot tone function with both transmitter
and receiver.
y With an ew 500 transmitter and the ew 500 G2 receiver or
vice versa:
Deactivate the pilot tone function with the ew 500 G2
transmitter or receiver.
