Warning!
It ‘s very important to set the head rotation limits in order to avoid antenna damage
Before to switch on the system be sure that nobody is close to the head
Before to get close to the head switch off the system
Stay away from head during rotation, keep a safe distance
Put warning signs near to the installation site of the head
The socket utilized for the unit supply must have the appropriate ground conductor.
The connection of the unit , to a socket without the ground conductor, will make the whole
equipment dangerous for people safety.
About the repairing of the units please refer to specialized personnel only .

Before opening the cover switch off the unit, disconnect the connection and
the supply cables.
In case of electrical shock please follow the instructions
of first aid listed on page 4
Substitute the fuses interrupted with others of the same type and voltage.
The waste disposal of the devices must be executed in the respect of the enforced laws in
the country uses. Eurotek not assumed responsibility for waste disposal in

First aid: artificial breathing(mouth to mouth)
1
In case of electric shock you have to ensure the first aids to
the patient, but to do this you have to consider two very
important things:
- interrupt immediately the electric circuit;
- if the circuit has not been interrupted, do not touch
the patient with bare hands; After doing this, without delay contact the nearest mobile
unit of first aid and practice to the patient, in case of loss of
consciousness, the breathing mouth to mouth as described
below.
2
Put the patient lying on his back with the arms parallel to
the body, ensure that he does not have the breathing tracts
obstructed (chewing-gum, dental prosthesis, etc.),
otherwise set him free from foreign bodies.
Kneel near the patient’s head and putting a hand under his
neck, incline as possible his/her head backwards.
3
Going on with keeping the patient’s head inclined with one
hand, use the other one to occlude the nostrils, if you are
going to practise the breathing through the oral cavity, or
occlude the mouth if you want to do it through the nasal
cavity.
While doing this begin the auto-oxygenation, with deep
breathing.
Then practice the artificial breathing blowing in the chosen
cavity beginning with ten expirations each minute to go on
them with twelve and fifteen.
4
During the breathing procedure you have to control that the
patient’s chest dilates, otherwise change cavity where to
blow the air because the previous one could be obstructed.
5 Do not ever stop the artificial breathing until the patient
has recovered or the first aid unit has come.

1. INTRODUCTION
The A4D-ESxR/1 (multi-channels) and A4D-ExR/1 (single-channel) is a family of transmitter
boards able to works from 3 GHz up to 15 GHz with excellent performances in term of output power
and spectral purity. The A4D-ESxR/1 boards have beeen designed in order to guaranty a reliable
connection in a point to point radio link and they can operate in indoor environment.
The design has been carried out taking in consideration quality, cost and reliability by using first
class solid stade devices along with a careful choise of the design architecture.
The end user can easily access and monitor the boards trough the EK-MFR/x equipment.
All Eurotek products are designed according with the ETSI recommendations.
2. THEORY OF OPERATION
The main task of the A4D-ESxR/1 boards is to convert an RF signal down to a 70 MHz IF, this is
accomplished by using two down-conversion step in order to keep as low as possible the spurious
emission. A band pass filter is inserted after each down-converter and a number of solid state
amplifiers keep the signal level controlled and stable in order to avoid unwanted distortions. One of
the main issue concerning the down-conversion process is related to the local oscillator phase noise
wich must not exceed the maximum allowed by the whole system, the only way to keep the phase
noise low enough to be compliant with the demodulator specs, is to implemt for each VCO a phase
locked loop able to stabilize the frequency and reduce the overall close-in phase noise.

3. BLOCK DIAGRAM
The block diagram description is valid for the complete board family, only minor differences will be
pointed out if essential to the reader understanding.
Each board has two main accesses, the first one is for the IF analog signal and the second one is a
pure digital access devoted to board management.
3.1 DUPLEXER
The connection between the indoor unit EK-MFR/x and the oudtor unit is made through a coaxial
cable carring the 70MHz IF signal, an FDM control signals and the power supply. The modulated
carrier is dropped by the duplexer and demodulated in order to establish the communication between
indoor and outdoor units. The low pass filter inside the duplexer selects the bias volage to be applied
to the DC/DC converters .

3.2 IF ANALOG SIGNAL PATH
The IMG2 signal is amplified by the first low noise amplifier, the RF signal is then down-converted
to the IMG1 using an image rejection aimed to reduce the overall noise figure. The signal is
amplified before to be down converted to the 70 MHz IF in order to keep the noise figure as low as
possible.
All the filters distribuited in the Rx line up have the purpose to remove the unwanted signals that
could convert thermal noise to the IF frequency.
The two local oscillators are both part of a phase locked loop in order to guarantee both the long term
frequency stability and the phase noise to be as low as possible. The secod LO (LO1) is a fixed
frequency oscillator while the first one (LO2) can be tuned in order to select the RF channel(see par.
3.4).
3.3 DIGITAL CONTROL
The unit is completely controlled, through the EK-CDP/x board (see EK-CDP/x user ‘s manual), by
a microprocessor and the standard interface to the mainframe EK-MFR/x allows an easy access to
the board. The power control loop is fully controlled by the mainframe.
