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
US TV EXPLORER II 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.
