Power of the received RF signal

In display panel , the power of the received RF signal (in μV) and the level control of the AF signal (in %) � i.e. the modulation of the RF signal � are shown. Both displays have an overmodulation display. If the signal is too high, �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.

Note If, with multi-channel systems (more than tree channels), the overmodulation display (�PEAK�) for the AF signal lights up during normal operation, the RF level should be reduced at the receivers in order to avoid intermodulation interference. In this case, increase the distance between receiving antennæ and transmitters or use attenuators in the antenna inputs.
