surface.
• the neck and tilt the head backwards to free
the airway system (Figure 1).
Figure 1
• If needed, open the victim’s mouth and check
for breathing.
• If there is no breathing, start artificial respiration
without delay (Figure 2) as follows: tilt the head
backwards, pinch the nostrils, seal your mouth
around the victim’s mouth and give four fast
rescue breaths.
Figure 2
• Check for heartbeat (Figure 3); if there is
no heartbeat, begin chest compressions
immediately (Figure 4) placing your hands in
the centre of the victim’s chest (Figure 5).
Figure 3 Figure 4 Figure 5
• One rescuer: give 2 quick rescue breaths after
each 15 compressions.
• Two rescuers: one rescue breath after each 5
compressions.
• Do not stop chest compressions while giving
artificial breathing.
• Call for medical help as soon as possible.
3.1.2 If the victim is conscious
• Cover victim with a blanket.

4.2 Features
This exciter contain a low-pass filter that reduces the harmonic emission to provided
for by international standards (CCIR, FCC or ETSI) and can be connected directly
to the antenna.
Two major features of TEX30LCD/S are compact design and user-friendliness.
Design is based on a modular concept: the different functions are performed
by modules that, for the most part, are connected through male and facilitates
maintenance and module replacement.
The RF power section of the TEX30LCD/S features a MOSFET module delivering
up to 30W output power.
Operating frequency stability is ensured by a temperature-compensated reference
oscillator and is maintained by a PLL (Phase Locked Loop) system. The exciter
will go into frequency lock within 30 seconds after power-on.

5.1 Preparation
5.1.1 Preliminary Requirements
The equiment ventilation and the work space must be suitable for maintenance
operations according to the directive in force in the country in which this device
is installed.
It is necessary to leave a minimum distance of 50 cm on the front and back sides
of the device to have a proper functioning and to facilitate air circulation through
the ventilation grids.
In any case, the device must respect the distance established by the safety directive
in force in the country where this equipment is installed.
This device is designed to operate at -10 °C to 45 °C without loss of performance.
The ambient air must be clean of dust and not condensed; the maximum humidity
must never exceed 95%.
It is important to remember that strong changes in temperature can lead to
generation of condensation, in particular environmental conditions. In case of the
station where this device is located should be subjected to these physical events,
it is good to monitor these devices, once you put it into service, in addition to trying
to protect the device itself as much as possible.
IMPORTANT: never supply voltage to the equipment in presence of condensation.
This problem can occur more frequently in devices warehoused for a long time or
in those used as an active reserve.
The antenna RF, power supply and connection cables must have the section
suitable for the maximum current intensity.
5.1.2 Preliminary checks
Unpack the transmitter and immediately inspect it for transport damage. Check
carefully that all the connectors are in perfect condition and check for the absence
of humidithy. Otherwise, wait until it is completely dry.
In case of problems in this step, immediately contact after-sales assistance.
The mains power supply protection fuses are conveniently located externally on
rear panel. Remove the fuse holder with a screwdriver to check its integrity or to
replace it if necessary. The following fuse are used:

5.1.2 Placement of equipment
Useful tips for a correct installation:
• Do not use in presence of external elements near inlets and outlets ventilation
systems, as they could prevent a proper ventilation of the device.
• Do not place near any source of heat or flammable gas.
• Avoid places subject to accumulation of humidity, dust, sand, salt or environments
that could compromise the correct operation of the equipment.
• Avoid installing the equipment into inhabited places due to possible noise
pollution or on fragile supports. The operation of the equipment can cause a
noise due to forced ventilation. The mounting surface must be able to withstand
the weight of the device and must be sturdy.
Note: below we will refer to a complete station, where the device can be a part of
it. The same procedures also apply in case of the device is used individually.
The device is usually connected inside a 19 “rack and fixed with M5 screws in the
appropriate holes.
The equipment must be installed at least 1 mt from the ground.
Install the rack in the point in which the transmitter will be put in operation. The
rack is mounted on wheels for easy movement so that, once placed in the desired
location, it is advisable to use the four screws located at the base of the rack to
stabilize it perpendicularly to ground.
The environment, where you have decided to install the rack, should be set up
for about 25°C of air conditioning and equipped with a filter to remove dust and
salt air.

Connect the overall power cord of machine. The cable can be slid through the
cable gland located on the back, or on the roof, of the machine and conductors
must be attached to the general disconnecting switch terminals.
Note: The connection of machine to power supply is done by fixing a multi-pole
cable with exposed terminals to a terminal board. Make sure, with no possibility
of error, that the cable is not under tension when you connect it to the machine.
WARNING: Is highly recommended to don’t turn on the machine without first
having connected the RF output to antenna or dummy load!
If you have a dummy load capable to dissipate the RF power generated by the
transmitter, it is advisable to carry out first tests by linking to it rather than to the
transmission antenna.
If transmitter require a single-phase power with F (black or brown or grey) + NF (black or brown or grey) + N
