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 pro
sthesis, 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 on
e 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 artific
ial 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. GENERAL DESCRIPTION
EK-MFR/1 works as a new flexible and modular platform that allows the simultaneous use of
different kind of boards inserted in its inner part in completely reconfiguration way. All the inserted
boards, in the device, are automatically identified by the integrated operating system, that fits the
functions of the keys and the visual information available on the color display placed in the frontal
panel. Inside the EK-MFR/1, a RTC (real time clock) works as a temporal reference for the
memorization of the alarms that have been verified in the system. Any relative board alarms are
signaled on the display sequential: a red LED (ACTUAL), on the frontal panel of the EK-MFR/1,
indicates that an actual alarm is in progress; a yellow LED (STORED), will indicate the
memorization of previously happened alarms. Thanks to this function the user will be able to
examine a log file stored inside the EK-MFR/1 and verify the type of alarm, the time and date in
which the alarm occurred as well as the time and date in which the alarm stopped. The setting
operation of every single board can be done locally on the keyboard, or by remote sites thanks to the
placement of Ethernet 10/100 Base T interface located in the power supply section (EK-PWS/X ).
Inside the EK-MFR/1 a re-configurable connection lines are inserted (matrix); they allow the
connection among all the slots inserted in the system leading therefore to an interconnection of the
signals that transit from one board to another one, without the necessity to use an uncomfortable
external connection. If the position of the inserted boards is changed by the user, is necessary to ask
information to the Eurotek about the software configuration system.
In order to set the operating functions of the system there are two different password levels: one in
reading mode only and the other one in reading/writing mode. Operating in this system it will be
possible to deny the access in writing mode to unqualified users meanwhile the configuration settled
will appear on the screen giving at the same time the chance of checking how the system works.
The background of the keyboard on the frontal panel is lighted in order to obtain a rapid setting
identification, also in critical visibility (e.g. OB – Van, mobile production, etc.). It is also possible to
set the switch off time of the display to reduce consumption.

4. DISPLAY AND KEYBOARD
4.1 Display and keyboard description
When the general switch (par. 2.2, front panel description) is turned on, the booting of the system is
running. At the end of the booting the EK-MFR/1 is in stand-by modality (the display shows a black
view) and after the user has pushed any of the keys, the display shows, the following configuration:
Pressing the “enter” key (par. 2.2, front panel description), it is possible to start the insertion
password operations (if the user, after the booting, press the “enter” key, the password insertion
procedure immediately started).
A flashing cursor indicates that a special password, of five number, must be inserted. The procedure
for the insertion of the password is explained below:
• Press the “modifying variable” keys (par. 2.2, front panel description) to visualize the
number from 0 to 9.
• Choose the first value to insert, and confirm it with the “enter” key.
• Insert the second value, confirm it, and repeat the procedure until the last number.
If an error occurs, the user must press the “escape” key (par. 2.2, front panel description), the cursor
returns to the previous position and the new value can be inserted. The password value must be
included from 00000 to 99999.
There are two types of password that the user can digit: reading only or reading/writing.
When a password is inserted, in the left down corner on the display it is possible to see the key
symbol with the RO letter if the password is read only type, or RW letter is the password is
read/write type.

When a type of password is inserted, the user can explore the following main menu:
MAIN MENU
>Main EK-MFR/1
>Slot 0
>Slot 1
>Slot 2
>Slot 3
>Slot 4
>Slot 5
Using the “explorer menu” keys (par. 2.2, front panel description), it is possible to see, on the
display, the boards that the EK-MFR/1 contains and the relative slot associated to the board. The
example below shows the EK-UNM/1 board that is inserted in the slot number 4. Pushing the
“enter” key, it is possible to enter in the selected board menu.
The RW letters appear, in the figure above, near the key symbol; this indicates that the actual active
password allows to read and modify the value of the variables in every board inserted in EK-
MFR/1.

If any of the boards is not inserted in a particular slot of the EK-MFR/1, the display shows the
following situation:
4.2 Display mode
A possible video signal of the inserted boards, are visible on the display that moreover supplies the
output interface of the EK-MFR/1 processor.
Every slot has the interconnections for two video signals, that can be showed on the TFT colour
monitor if the board is enabled for this function. There are three different modalities: either only the
text is showed, or the text and the video are showed or only the video is showed.
Every different modality can be settled pushing the “explorer menu” keys simultaneously (display
mode function).

5.2 Menu description and keyboard guide
The description of every single menu of the EK-MFR/1 is as follow:
>Passwords
The Passwords menu allows to modify the reading only and the reading/writing password. To do
this, the user must digit the password provided by the Eurotek, when the general switch (par. 2.2,
front panel description) is turned on and the booting of the system is complete (par 4.1 display and
keyboard description).
The next example shows how to change the reading/writing password.
When inside the EK-MFR/1 menu, the “enter” key (par. 2.2, front panel description) is pushed, the
display will show the passwords menu configuration:
Pushing again the “enter” key, the user can enter the two internal menus for the setting of the
passwords value, (in this example the menu is RW/PWD), while pushing the “escape” key (par. 2.2,
front panel description) the display returns to the passwords menu configuration (like is showed in
the figure above).
When the R/W PWD menu is on, the user must digit the “enter” key to start the insertion password
operations (par 4.1 display and keyboard description).

>Power loops
The Power Loops menu allows to control automatically the output level of one board inserted in a
slot in according to the output level of a board inserted in another slot of the EK-MFR/1. This
functionality it used in order to keep constant the output power of a transmitter to adjusting the
modulator output power.
The three loops are therefore in a position to adjust three different transmitters connected to the
same EK-MFR/1; to simplify the process we are analyzing the relative function to LOOP1, which is
identical to the other two. The Loop 1 menu is composed by five sub-menus: Enable 1, Source 1,
Target 1, P Goal 1, P Source 1.
BLOCK SCHEME OF THE POWER LOOP SYSTEM
In the sub-menu SOURCE we define in which slot of the EK-MFR/1 the EK-CDP/1 board is
inserted, or otherwise which is the signal that the program will read in order to set the slot TARGET
in function of the P-GOAL power that we want to keep during the operation.

The next example explains how to set the Power Loops modality.
We suppose to have loaded the EK-MFR/1 with the boards represented in the following figure
 Slot 0: Empty
 Slot 1: EK-CDC/1 (MPEG2 codec)
 Slot 2: Empty
 Slot 3: EK-CDP/1 (coaxial adapter)
 Slot 4: EK-UNM/1 (modem)
 Slot 5: Empty
We analyze the setting of every single menu of the Power Loops supposing of working with the
QPSK modulations to obtain a back-off of 4 db relating the saturate power (0 db) of the transmitter
SHF connected to EK-MFR/1 by the EK-CDP/1 board.
1. >>>Source1 = slot3: indicates where reading the saturate power
2. >>>Target1 = slot4: indicates where setting the IF power level in order to obtain the back-
off planned (EK-UNM/1)
3. >>>P Goal1 = -4db : indicates the back-off level to be obtained
4. >>>Enable1 = yes : the loop 1 function is enabled
Now an independent program of EK-MFR/1 will try to keep the power of the transmitter (EK-
CDP/1) constant in according to the power of the modulator (EK-UNM/1).

>Save Config
EK-MFR/1 allows to store four configurations system. To save a personal configuration, it is
necessary to enter in the Save Config menu; it is possible to choose on which configuration to store
the personal system settings pressing the “enter” key and using the “modifying variable” keys (par.
2.2, front panel description). The four possible configurations to be used are: Config 0, Config 1,
Config2 and Config3.
>Get Config
The Get Config menu allows to recall one of the four possible configurations stored in the Save
Config menu using the Get from function.
>Miscellaneous
The Miscellaneous menu allows to monitory and control many EK-MFR/1 functions, by the
variables listed below:
>>Volt in 0: Allows to read a DC voltage (0÷12 VDC) eventually present on the
pin 4 of the auxiliary connector of the EK-PWS/X board.
>> Volt in 1: Allows to read a DC voltage (0÷12 VDC) eventually present on the
pin 17 of the auxiliary connector of the EK-PWS/X board.
>> Volt out 0: Allows to set a DC voltage (0÷12 VDC, 10 mA max) at the output of
the auxiliary connector (pin 5) of the EK-PWS/X board.
>>Volt out 1: Allows to set a DC voltage (0÷12 VDC 10 mA max) at the output of
the auxiliary connector (pin 18) of the EK-PWS/X board.

5.3 Temperature control
EK-MFR/1 allows a reliable control of the temperature. To minimize the use and the maintenance of
the two fans, EK-MFR/1 controls the rate of the same fans. The highest temperature registered on
the inserted boards is used to control the fans. The monitoring of the board temperature can be done
in the sub-menus and the memorization and settling of the limits can generate possible alarms.
6. LEDs AND ALARMS
6.1 LEDs description
• On (green light) : indicates that the EK-MFR/1 is active. The light is always on also if the
display and the keys are off (if the user has to set the time to exit in the Miscellaneous menu
of the EK-MFR/1).
• Actual (red light) : indicates that an alarm is present, a variable of any of the boards does not
respect the limit. The light turns off when the variable returns inside the limit.
• Stored (yellow light) : indicates that an alarm is present, the light turns off when any of the
keys is pushed.
The LEDs position is reported in the front panel chapter.
6.2 Alarms description
The next example explains how the display shows when an alarm occurs.

The Slot 4 Viterbi Ber row, indicates that the Viterbi ber variable is out of the limits and an alarm is
present (LED Actual, par. 6.1, LEDs description). Slot 4 Viterbi Ber row is flashing until the
variable is out of the limits.
It is possible that more alarms are simultaneously present; in this case the alarms are showed on the
same row on the display every two seconds. This function allows to have a general information of
the alarms without to explore the menu of every used slot.
7. ABOUT OPERATING SYSTEM
7.1 Operating system connection.
It is possible to connect the EK-MFR/1 with a terminal unit to use the RS232 interface (to see the
rs232 interface settings in the Appendix C) or the Ethernet 10/100 Base T interface. The connectors,
of these interfaces, are visible in the chapter 3 “rear panel”. The description of the connectors, with
the pins indication, is reported in the EK-PWS/X user’s handbook.
When the EK-MFR/1 is connected and the general switch is turned on (par. 2.2, front panel
description), the insertion of the EK-MFR/1 login is required:
EK-MFR/1 login:
The user must enter in the system using the super_user login, and digits it as follow: (after the
insertion of the login is necessary to push the return key ( ) to execute the command).
EK-MFR/1 login: super_user
Now, it is necessary to insert the password value: pollon
Password: ------
When the password is correctly inserted, the prompt of the operating system appears, on the screen
of the terminal unit, as follow:
$
The user is connected to the system now.
7.2 Operating system commands
When the login operations are executed, it is possible to digit the operating system commands. To
execute them, the return key on the terminal unit keyboard must be pressed.
7.2.1 Read_log
The read_log command allows to examine the status of the alarms of the entire system. When this
command is launched, the situation below appears on the screen of the terminal unit:
$ read_log
