In order to select the supply voltage of the external units, press
the screen will display a functions menu labelled EXT. SUPPLY listing the choice of
voltages (which will depend on the band being used). Turn the rotary selector [1] to the
desired voltage and press to activate it. The following table shows the choice of supply

In the External power supply mode is the unit powering the amplifiers before the
antenna (terrestrial television) or the satellite TV receiver (house-hold or community)
also powers the external units.
The DRAIN [3] indicator lights when current is flowing to the external unit. If any
kind of problem occurs (e.g., a short circuit), an error message appears on the monitor
('SUPPLY SHORT'), the acoustic indicator will be heard and the instrument will cease
to supply power. The PRODIG-3 does not return to its normal operating state until the
problem has been solved, during this time it verifies every three seconds the
persistence of the problem warning with an acoustic signal.
