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.

Package description
Any equipment is always supplied by us inside a suitable package for a
safe freighting, to avoid damages to the equipment due to small shocks.
Basically, the package is a carton box sealed with adhesive tape with the
manufacturer brand name, then externally tighten by a wide plastic cord.
In case one or more sides of the box have a different tape with respect
to the original one, it means that the box has been opened during the
despatch operations; this should be reported in an attached sheet.
At the time of opening the package, if a damage of the equipment or if
something is missing, we recommend to fill up the form which is included
in the manual, and accurately describe the inconvenience.
Upon that, the manufacturer will check where the problem may have
occurred and will decide to grant the replacement and if due , the
correspondent refund.
Besides the equipment, the carton box package should include:
1) Polythene bag
2) Polystyrene bottom and cover

Installing operations
The installation of any electrical equipment should be always made
by technical and specifically trained technicians, who are supposed
to be aware of the risks related to the connection to an electrical supply.
Before proceeding to the installation, it is mandatory to verify that the
general electrical supply is fully in compliance with the normative of the
Country where the equipment will operate.
In the rear panel of the equipment, the requested electrical features of
mains are reported.
The utmost attention should be devoted to the grounding
system of the mains: this grants the personal safety of the
technical personnel in case of stray currents due to static voltages
accumulated in the equipment.
Before proceeding to any operations, we strongly recommend to make
sure that an adequate and certified grounding system has been set.
In case of disregard of the above mentioned recommendations, the
manufacturer does not take any responsibilities about damages to
persons and materials.
nce the place where the equipment will be situated, it is important to
verify the compliance with some specific criteria.
Any materials or objects should be placed at a distance of at least 30cms
from the cooling air ducts of the equipment. This will assure the regular
cooling conditions of the heat-sink of the equipment.

Disregarding the above mentioned advises and recommendations will
bring damages to the internal components and risk of fire
Make sure that the equipment is placed in a stable and secure position,
to easily allow the access to the front panel and to the rear panel too.
This will permit in the future a simple and fast inspection of the
connections if they are necessary.
First, connect the transmitting antenna cable to the correspondent N type
male connector placed in the rear panel; then connect the receiving
antenna cable.
Eventually connect the included power cord to the female plug placed on
the rear panel and protected by a fuse, and then connect the other end
to the mains plug.

Maintenance and cleanness
Routine maintenance and cleanness can be exclusively done when the
equipment is not connected to the mains. Disregarding this caution, may
have the effect of serious problems to the personal safety.
For no reasons, the equipment should have any contacts with water or
other liquids.
To clean the equipment, only use a soft cloth. In case that much dust is
accumulated inside the equipment, use a vacuum cleaner or a dry and
soft brush to remove it.
The routine maintenance of the equipment is intended also as the
periodical control of the operational parameters, following the instructions
written in the chapter “putting in operation”.
