Power Of The Received Radio Signal - Sennheiser EM 3031-U Notice D'emploi

13 Power of the received RF signal
In display panel , the power of the received RF signal
signal – i.e. the modulation of the RF signal (in %) are shown. Both displays have an
overmodulation display. If the signal is too high, the text "PEAK" lights up briefly. Short
overmodulation is not critical. Where longer overmodulation occurs, the modulation of the
corresponding transmitter must be reduced. For the AF signal, "peak hold" is also shown, which
means that short peaks remain visible for some time.
14 Squelch (Muting)
The EM 3031/3032 receiver is equipped with an adjustable squelch control which eliminates
annoying noise when the transmitters are switched on and off. It also suppresses sudden noise
when a transmitter leaves the reception area and there is no longer sufficient transmitter power
received by the receiver.
The squelch is adjusted on the rear of the receiver with control
range is between 0 and about 100 µV. When the squelch is active, the text

AF squelch
The squelch also switches on when the selected radio channel is occupied by a wideband interference
signal such as that generated by lighting control systems. This prevents an interfering signal from
hindering reception even when the interfering signal has a high RF level. When control
(" ") is set to position "0", the AF squelch is also switched off.
