USAGE INSTRUCTION

Connected a 50 Ωload or 50 Ωantenna to the RF output, connect the
equipment into a mains supply (100÷240 VAC) with earth point. The
transmitter equipment is factory pre-set to 0.0 W.
Switch ON the power switch and the yellow V POWER led will light.
The Display will show:
After 3 seconds the green PLL LOCK led will light and the Display will
show an increasing bar, after a further 5 seconds the green ON AIR led
will light and there will be output power.
At this point the Display will show the next parameter for the transmitter:
•Level Modulation (MOD > );
•Forward Power (FRW 5.0W);
•Reflected Power (RFL 0.1W);
instead for the receiver:
•Level Modulation (MOD > );
•Level Signal(50dBuV).

Environmental conditions for the installation
Each equipment produced by our Company has been carefully designed
and tested in compliance with the European normative.
The reported marks placed in the rear panel and in the manual are
relevant to the tests realized on the equipment according to rigorous
safety criteria advised by the Country where the equipment will operate.
Some tests require that the equipment is able to stand specific very
severe environmental conditions for a brief period of time.
Although the equipment is actually able to operate properly even under
severe conditions they haven’t to be considered as regular and
therefore cannot be applied neither permanently nor for long periods.
The manufacturer has designed the equipment for lasting duration
provided it operates under correct environmental conditions.
In other words the equipment can stand extreme environmental
conditions for a limited period of time at the same time operating in
compliance with the quality figures advised in the technical data-sheet.
In case the equipment is expected to operate under very critical
conditions which have been previously advised by the end user upon
his request the design of the equipment will be then reconsidered to
make it suitable for the severe environmental conditions in order to save
the regular technical data.
The ambient where the equipment operates should be dry and with no
dust; the ambient temperature is supposed to be within the range
advised by the manufacturer.

No material such as a rope insulating material or clothing should cover
the equipment at any time. Make sure that no kind of materials or objects
can somehow reduce the regular cooling air flow through the equipment.
Before operating the equipment make sure that all the advises reported
in the manual are fully complied.
In this section the data concerning the minimum room where the
equipment should operate are intended as minimum figures sufficient to
keep the internal parts of the equipment perfectly cooled.
In case that in the same shelter more equipment are placed it will be
necessary installing an effective air condition system to ensure the
recommended operational conditions. It is understood that in case the
advised conditions are not complied the manufacturer will not be liable
for any inconveniences or damages that may occur as the warranty
conditions will be void.
