1.4 MAINTENANCE
Maintenance concerns all the actions aimed to maintain or restore the equipment
operativity.
Maintenance can be preventive (scheduled maintenance) and corrective (unscheduled
maintenance).
In order to schedule maintenance interventions it is necessary to divide maintenance
into levels according to the operations to be carried out.
The maintenance levels define the actions and the personnel allowed to carry out the
maintenance operations.
Three maintenance levels are thus defined:

I:
Equipment Maintenance Level.

II:
Module Maintenance Level.

III: Component Maintenance Level.
For example in a TETRA system we can define:

Equipment:
any radio terminal (Hand-held, vehicular or fixed).

Module:
a Base Band of TTU400 of the Base Station BS400.

Component:
any part of a module (e.g. an IC).
A description of the maintenance levels is shown in Tab. 1.2.

SAFETY RECOMMENDATIONS
Carefully read all of the cautions and warnings before using the vehicular radio:
Do not use the radio equipment for uses different than those
indicated in the manual.
For a correct use of the radio equipment, read what is listed in the
user's guide.
Protect the radio from sprinklings of water and/or other liquids and
from dust.
Be careful not to damage the vehicular radio when cleaning the
vehicle.
Do not place the audio accessories above the airbags or in their area
of action. If the airbag is activated, it may not swell correctly and/or
hurl the audio accessory, with great force, inside the passenger
compartment where the vehicle occupants are located.
Do not use the vehicular radio if the antenna and/or the antenna cable
are damaged.
The electronic devices are sensitive to electromagnetic interference
(EMI) if not adequately shielded, designed or configured differently
for electromagnetic fields immunity.
If electromedical equipment (ex. pace-makers, acoustical equipment,
etc.) is used together with the vehicular radio, make sure that it is
adequately shielded from external electromagnetic fields.
Do not take the radio into environments that have a potentially
explosive atmosphere (ex. fuel storage sites, filling stations, etc.).
Selex ES - Proprietary information

VS4000
Technical Handbook
General Information
Install the vehicular radio following the instructions given in the
installation guide. The mounting screws can damage cables and
wires that run under some mounting surfaces in the vehicle. Be
careful to avoid mounting the bracket above these locations. The
equipment must be installed in such a way that it complies with the
national regulations in effect.
Carry out the maintenance interventions on the vehicular radio
following the instructions given in this technical handbooks.
Follow all accident prevention standards when carrying out
maintenance interventions on the vehicular equipment and use the
proper tools (spanners, screwdrivers,…..).
First and second maintenance level interventions on the equipment
are to be carried out by authorized technicians only.
Third maintenance level interventions are to be carried out by Selex
technicians only. The maintenance levels are defined in this technical
manual.
Use only original accessories and spare parts, or approved by the
manufacturer, suitable for the vehicular radio. The use of different
accessories and/or spare parts (earphone, antenna, etc.) makes the
safety and electromagnetic compatibility certifications to be valid no
more and it could lower the user safety level and/or generate
electromagnetic fields that exceed the accepted limits.
After the radio has been trasmitting for a long period, it may reach
high temperatures: in such a case avoid touching the radio shell.
WARNING
The emergency call is a priority type call.
The vehicular radio, like all mobile telephony equipment, operates
with radio frequency signals, therefore, the forwarding of the call
depends on the network coverage at the moment of the call.
Page 10
Selex ES - Proprietary information
P/N: MAN-0974/01

VS4000
Technical Handbook
General Information
If you need send an emergency call, keep pressed the emergency
button for at least 2 seconds, when the radio is switched on. Relating
on the radio setting (from PRP), two cases may occur if the
trasmission is inhibit:
a) the emergency call is not sent; it is necessary to disable the Tx
Inhibit founction from radio menu to foward a call (even if the call
is an emergency call).
b) the emergency call is sent and automatically the Tx Inhibit
function is disabled; from radio menu it is possible to recover the
Tx Inhibit function again
The radio complies with all product specifications and great care is taken by the
manufacturer so that user safety, as far as the effects of electromagnetic waves on
health are concerned, is guaranteed within the limits established by the international
specifications.

6. TROUBLESHOOTING
The radio terminal VS4000 troubleshooting techniques are described in this section.
These techniques are meant to find out failures that cause a bad functioning of the
equipment.
The information given in this manual takes into consideration the fact that all the III
level maintenance operations will be done only by the Selex ES assistance
technicians.
The descriptions of the replacement procedures which can be done by the purchaser
are detailed in section 7 of this technical manual.
6.1
INTRODUCTION
The troubleshooting procedures are shown in flow diagrams (see par. 6.3.1). The tests
to be carried out by the use of the Radio Test Set on the radio terminal VS4000 are
described in chapter 6.2. These tests are aimed to find out whether or not the
equipment works correctly, under a radio point of view. If not, it must be sent to the
Selex ES assistance centre.

RADIO TESTS WITH THE RADIO TEST SET
6.2.1
Tests with Radio Test Set
To carry out the Power Test and the Sensitivity Test on the radio terminal, you need a
TETRA RADIO TEST SET (IFR) with the power supply cable and a TNC cable, as well
as the radio terminal to be tested.
Note
Several functions can be active on the TETRA TEST SET, depending on the release.
To carry out the test:

turn off the RADIO;

disconnect the antenna from the RADIO and replace it with the TNC cable;

connect the other end of the TNC cable to the TETRA RADIO TEST SET; turn on
the TETRA RADIO TEST SET (see Fig. 6.1).
Note
If the radio terminal to be tested is a portable one (Puma T2/T3), connect to the test set on the most
sensitive RF connector (1W); to select this connector, press the “RF select” button; the two leds next to
the connection selected will light up. By default, the Tetra Radio Test Set sets itself on the least
sensitive RF connection (150 W), signaling it with the lighting up of the relative leds; this connection
should be used in all cases in which the radio to be tested supplies a maximum power greater than 1
Watt.

Troubleshooting
When the TETRA RADIO TEST SET is turned on, a screen appears on the display
with the initials IFR; the test set saves the data relative to the last test carried out in the
memory.
By default, the TETRA RADIO TEST SET sets itself in analog mode; to select digital
mode, press the ”SYSTEMS” key (see Fig. 6.2) to load the TETRA protocol.
Fig. 6.2:
SYSTEMS key
Before carrying out the test, it is necessary to know which channels are set on the
terminal (setting from PRP). Even if there is more than one channel set, it is sufficient
to consider just one of them for the purposes of the test.
When the “TETRA MOBILE” key is pressed from among the keys to the right of the
display (see Fig. 6.3) and, subsequently, when the key in correspondence to “SET-UP”
is pressed (from among the keys to the left of the display), a screen appears on the
display that allows visualizing “SYSTEM PARAMETERS”; press the “CHANNEL PLAN”
key to carry out the search for the reference frequency of the terminal being tested
(see Fig. 6.4).

Channel selection
Once the frequency has been found, confirm it by pressing the key that corresponds to
the operating frequency of the terminal from among those located to the right of the
display; the test set finds the frequency band and, when the “CONTROL CHANNEL”
button is pressed, shows all of the available parameters. Enter the value of the
parameters using the numeric pad (see Fig. 6.5).

Troubleshooting
Note
If the frequency band of the terminal under test does not appear among those available to the test set,
proceed by creating a personal “SET UP” to insert it (see IFR manual relative to the TETRA TEST
SET).
Press any one of the red “ENTER” keys to confirm data entry (see Fig. 6.6)
Fig. 6.6:
Red “ENTER” keys
Note
It is possible to obtain confirmation (ENTER) by pressing any one of the red keys only when you are not
required to press a specific key (ENTER) relative to the required measurement unit.
Note
It is possible to reduce the frequency search time through the “BASE COLOUR CODE” item only when
several groups of cells are found under the same area.
Once the values relative to the first group of essential parameters have been entered
(which are highlighted on the display), press the “MORE” key to highlight the second
group of parameters, in order to be able to enter the values relative to these also.

 min Rx level for access:
-110 dBm (indicates the minimum signal level
coming from the BS in order that it be considered by
the radio terminal);
 max Tx level:
30 dBm (corresponds to the maximum signal level
transmitted by the terminal: 1 W for portable
terminals; 10 W for vehicular/fixed terminals);
 access parameters:
-39 dBm (this value is given by a relation involving
two parameters, C1 and C2, to determine passage
from cell to cell);
the other parameters in this second group are not useful for carrying out the test
in question.

Troubleshooting
Press the “MORE” key again to access the parameters of the third and last group;
none of these are useful for carrying out the test.
Note
If the parameters of the first group are not entered, the test set remains in “wait mode”; if, instead, the
parameters of the second group are not entered, the test set operates anomalously; finally, the
parameters of the third group do not influence the test in any way.
A screen divided into two parts (see Fig. 6.7) appears on the RADIO TETRA TEST

Now turn on the terminal to be tested; it begins to search and then registers itself with
its identifier (ITSI), which will appear on the display.
When “CALL MOBILE” is pressed, the test set sends a call to the terminal under test;
when the terminal accepts the call, it is possible to check the “MODE” data on the test
set.

Power Profile: ( “Passed” must appear).

Other parameters are (see Tab. 6.1) “Burst Power” (it can be expressed in dBm
or mW), “Timing Error” (indicates the number of symbols read erroneously),
“Frequency Error” (frequency error) and “Vector Error” (referred to the vector
(symbol) transmitted; the mean error (RMS), the peak error (PEAK and the
residual error (RESIDUAL) are specified).
Even if only one of the parameters does not comply with the ETSI standard (see Tab.
6.1), “Passed” does not appear next to “Power Profile”.

Carry out the necessary settings on
the Tetra Test Set (selection of the
TETRA environment, selection of
transmission mode, operating
frequency, etc.) to pick up the

article 7.1.1.2
(2): The TETRA RF test set will have a precision in frequency greater than 0.1 ppm (BS diagram)
or will be tied to a higher external reference precision. If similar conditions are not complied
with, this measurement is not reliable and should only be considered approximate.

Troubleshooting
In these tests, the TETRA TEST SET simulates the TETRA network.
Power Test
When the “CALL MOBILE” button is pressed on the test set, a call is forwarded to the
terminal being tested.
After having pressed the “RF GEN” button, vary the field using the adjustment knob
(see Fig. 6.8), weakening it and thus forcing the terminal to increase the transmitted
power until reaching its MAX power (1 W for portable terminals, 10 W for
vehicular/fixed terminals). The change in the fluctuating values (in dBm) will be noted
in correspondence to “RX GEN LEVEL”.
Sensitivity Test
The DYNAMIC SENSITIVITY tests are not carried out in the lab; for this reason, we
refer here to STATIC SENSITIVITY.
When the “CALL MOBILE” button is pressed on the test set, a call is forwarded to the
terminal under test.
After having pressed the “RF GEN” button, use the adjustment knob (see Fig. 6.8) to
bring the signal to -112 dBm, starting from a higher value (for example, -90 dBm).
The call, previously forwarded to the terminal, must remain active up to the value of 112 dBm; to guarantee this, the terminal under test will bring itself to the MAX power
value transmitted (1 W for portable terminals and 10 W for vehicular/fixed terminals).
At the end of the test, the operator, besides having carried out the POWER and
SENSITIVITY TESTS, also verifies the accuracy of all of the radio terminal
parameters.
Note
The POWER and SENSITIVITY TESTS are closely correlated; in fact, the power is controlled by
varying the sensitivity and vice versa.
