Introduction
The operations described below enable you to implement your Vokkero® Squadra communication system quickly
and easily.
All the operations described are common to the versions of the Vokkero® Squadra terminal listed below:
VOKKERO SQUADRA QATAR VERSION
Note: Your product reference is to be found on the label on the back of your terminal’s casing.
The system consists of three main items:
• The terminal
• The congurator
• The charger
All the operating parameters of the Vokkero® Squadra system are managed by the congurator. This provides
access to the settings menus via a touch screen. In order to function, the congurator must be connected to one or
more chargers and the charger(s) must be connected to the power supply unit.
Installation procedure for the system
• Connect the congurator to the charger(s).
• Connect the power supply unit to the last charger (if several of them are in series).
• Connect the power supply unit to the mains.
• Connect the Vokkero® Squadra terminals as shown below.
Note 1: The order and the position of the terminals on the charger(s) is unimportant.
Note 2: If the purpose of the operation is solely to charge the terminals, then there is no need for the congurator.

1.3. Description of the terminal’s keys
1.4. Start-up of the terminal – Important information
Before starting up your terminal, make sure that it has been properly charged using the
dedicated charger.
• To switch on the device, press the On/O󰀨 key and keep pressing it until it starts up, and
then release the key.
• To switch o󰀨 the device, press the On/O󰀨 key and keep pressing it until it is turned o󰀨.
2. Description of the congurator
The congurator does not have a connector enabling it to be powered directly, and it does not have an On/O󰀨 switch
either. To start it up, the congurator must be connected to one or more chargers. These must be powered from the
mains via the specic power supply unit supplied with the Vokkero® Squadra kit. The congurator is equipped with a
USB socket for updates, as well as a stylus which enables the touch screen to be used.
When the system is started up, the congurator displays the Vokkero logo, and then the home screen.
Note 1: All the parameters, including the volume setting, are retained when you switch o󰀨 the device and they remain
the same when you switch the device back on.
Note 2: The terminal automatically places itself in the power-saving mode after a few seconds if it is not being used.
This mechanism places the terminal’s LCD screen on stand-by. To wake up the LCD screen, press any key on the
terminal.
1.5. Setting up the headset
The headset supplied with the Vokkero® Squadra kit
must be connected the socket located at the base of the
terminal. Check that the connector is well installed in the
housing and secure the connexion by pushing strongly on
the connector. A poor connection may cause audio quality
problems, or the impossibility to hear and / or listen.

3. Warning about using frequencies
The Quick Conguration and Frequencies sub-menus provide access to the communication channels’ settings (radio
frequencies).
NB: Before using the device, please observe the legal provisions in force in your country. Please refer to the “CERTI-
FICATE OF TYPE APPROVAL” chapter at the end of this document.
You can parameterise the Vokkero® Squadra terminal on 3 di󰀨erent channels :
The frequencies for the various channels are as follows:
QATAR Class 1 channels:
• Q1 : 869.525 MHz (RF output power 100mW / 20dBm)
• Q2 : 864.500 MHz (RF output power 100mW / 20dBm)
• Q3 : 863.500 MHz (RF output power 100mW / 20dBm)
4. Automatic conguration of a Vokkero® Squadra system
Quick Conguration menu
Principle: the Quick Conguration menu makes it possible to very quickly congure all of the terminals connected to
the charger(s). The parameters required for operating the system (the encryption and the role number) are managed
automatically. The communication channel selection (radio frequency) remains manual. Note : the Quick conguration
mode does not modify the terminal parameters such as the volume, the sidetone level or le listening selection.
4.1. Selecting a channel
Procedure:
• In the main menu, click on the “Quick conguration” icon.
• A window will open, enabling the communication channel to be selected.
• Using the stylus, select the communication channel by clicking on it.
• Click on the “OK” button in order to validate it, or on “Escape” in order to exit from the sub-menu.
When the “OK” button has been clicked on, a window will appear conrming that the operation has been duly comple-
ted.
• Click on “OK” to return to the home screen.
The terminals can be removed from the charger(s) and be used. Note:when the terminals are removed from the char-
ger, they switch o󰀨 automatically, you must switch them on to use them.

5.2. Assigning a number to a system (Role menu)
To set up a conference, rstly you have to identify all the devices that will be taking part and give them a number
(role). A conference may be established between 2 to 8 devices, which will be identied by a number ranging from 1
to 8.
Note 1: One of the devices absolutely must have the number 1.
Note 2: Do not assign the same number to several devices, as this will prevent the conference from running smooth-
ly.
Procedure:
• In the main menu, click on the “Role” icon.
• A window will open, asking you to select the terminal that a role number must be assigned to. Click on the “OK”
button.
• Using the stylus, select the communication channel by clicking on it.
• A window will open, in which the terminal selected will be displayed.
• Using the “+” and “-” buttons, modify the role number (from 1 to 8 or “Listener” for a listening-only mode).
• Once the number has been selected, click on the “OK” button in order to validate it, or on “Escape” in order to
exit from the sub-menu.
When the “OK” button has been clicked on, a window will appear conrming that the operation has been duly comple-
ted.
• Click on “OK” to return to the home screen.
5.3. Setting the systems in conference mode (encryption procedure)
Principle: In order to communicate in secure mode, the devices must save an encryption key provided by the congu-
rator.
This operation is required in order to enable all the devices to take part in a conference in secure mode.
IMPORTANT NOTE
In encrypted (secure) mode, a device cannot communicate with a system if the encryption procedure has not been
carried out. If you want to add a terminal to an existing system, you absolutely must carry out this procedure with all
the system’s devices (including devices congured in Listener mode).
Make sure that each of the following criteria are fullled before starting the operation:
• All the devices must use the same channel.
• Only one device should have the ID 1.
Procedure:
• In the main menu, click on the Encryption icon.
• The Network Encryption sub-menu will appear and enable you to select two types of procedures: Launch Encryp-
tion and Remove Encryption. Click on the “Launch Encryption” icon.
• A window will open and ask you to conrm the launching of this procedure.
• Click on “Yes”.

209921A VOKKERO SQUADRA 8 - QATAR - User guide version V1.1

When the “Yes” button has been clicked on, a window will appear conrming that the operation has been duly com-
pleted.
• Click on “OK” to return to the Encryption menu.
• Click on “Escape” to return to the home screen.
The Encryption sub-menu also makes it possible to cancel an encryption procedure previously carried out on the
system.
This option may be useful when other Vokkero® Squadra terminals want to integrate the conference without having
the means of being parameterised by the congurator.
In this case, the act of cancelling the encryption procedure will make it possible to leave the channel used by the
system “open” and the other terminals will be able to participate in the conference (provided that they are all operating
on the same communication channel).
• In the main menu, click on the Encryption icon.
• The Network Encryption sub-menu will appear and enables two types of procedures to be selected: Launch
Encryption and Remove Encryption. Click on the Remove Encryption icon.
• A window will open and request conrmation of the launch of this procedure.
• Click on “Yes”.
When the “Yes” button has been clicked on, a window will appear conrming that the operation has been duly com-
pleted.
• Click on “OK” to return to the Encryption sub-menu.
• Click on “Escape” to return to the home screen.
Once these three stages (Frequency, Role, Encryption) have been completed, you can use your Vokkero® Squadra
communication system.
