External Units Power Supply
The
TV EXPLORER II / II+
can supply the voltage needed to power the external
units (antenna preamplifiers, in the case of terrestrial TV, LNB in the case of satellite TV,
or IF simulators).
In order to select the supply voltage of the external units, press
[11] key, and
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
voltages:

External units powering voltages.
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
TV EXPLORER II / 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.
