ECHOES Analyzer (COFDM)

The ECHOES function can detect and display echoes that may appear when
receiving simultaneously the same signal from several transmitters. Another reason that
can cause echoes is the reflection of the signal on large objects such as buildings or
mountains.
With the ECHOES function is possible to know the distance from where we are to
the transmitter or the object that has caused the echo. Thus, the installer can minimise
the effects of echoes on the facility. Knowing echoes, the installer is able to reposition
the antenna and therefore, reduce the effect of echoes received.
This feature is only available for DVB-T / H signals. Therefore, you should
configure the TV EXPLORER II / II + in order to receive this type of signals. If not, the
ECHOES function will not appear on the menu "Utilities".
The steps to go through to set up the digital terrestrial reception are the next:
1. Press the key
