COMPLIANCE TO FCC US/CAN
• This device complies with part 15 of the FCC rules.
Operation is subject to the following two conditions:
(1) this device may not cause Harmful interference, and
(2) this device must accept any interference received, including interference that may cause undesired operation of the device.
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC
Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This
equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instruc-
tion, may cause harmful interference to radiocommunication. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined
by turning the equipment off
and on, the user is encouraged to try to correct the interference by one or more of the following measures :
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
• CHANGES OR MODIFICATIONS NOT EXPRESSLY APPROVED BY VOGO COULD VOID THE USER’S AUTHORITY TO OPERATE THE
EQUIPMENT.
This device complies with license-exempt transmitter(s)/receiver(s) that comply with Innovation, Science and Economic Develop-
ment Canada’s licence-exempt RSS standard(s).
Operation is subject to the following two conditions:
(1) this device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that may cause undesired operation.
Under Industry Canada regulations, this radio transmitter may only operate using an antenna of a type and maximum (or lower)
gain approved for the transmitter by Industry Canada.To reduce potential radio interference to other users, the antenna type and
its gain should be chosen so that the equivalent isotropically radiated power (e.i.r.p.) is not superior than necessary for successful
communication.

Ce dispositif est conforme aux règles de la FCC part 15.
Son fonctionnement est sujet aux deux conditions suivantes :
(1) le dispositif ne doit pas produire de brouillage préjudiciable, et
(2) ce dispositif doit accepter tout brouillage reçu, y compris un brouillage susceptible de provoquer un fonctionnement indésirable.
Cet équipement a été testé et déclaré conforme aux limites d’un appareil numérique de classe B, conformément à la partie 15
des règles de la FCC. Ces limites sont conçues pour fournir une protection raisonnable contre les interférences nuisibles dans une
installation résidentielle. Cet équipement génère, utilise et peut émettre de l’énergie radiofréquence et, s’il n’est pas installé et
utilisé conformément aux instructions, peut causer des interférences nuisibles aux radiocommunications. Il est cependant toujours
possible que des interférences se produisent dans le cadre d’une installation particulière.
Si cet appareil produit des interférences nuisibles à la réception des programmes de radio et de télévision –détectables lors de la
mise hors tension ou en tension de l’appareil-l’utilisateur est encouragé à mettre en œuvre une ou plusieurs des mesures suivantes
pour remédier à ces interférences :
- Réorienter ou déplacer l’antenne de réception.
- Augmenter la distance entre l’équipement et le récepteur.
- Branchez le matériel à une sortie sur un circuit différent de celui auquel le récepteur est branché.
- Prendre conseil auprès du commerçant ou d’un technicien de radio/TV expérimenté.
• Tout changement ou modification non expressément approuvé par la partie responsable des mesures de conformité peut amener
l’utilisateur à se voir interdire l’usage de l’appareil.
Cet appareil est limité à l’exploitation des fréquences autorisées Partie 15, et ne peut pas être configuré par des utilisateurs finaux
ou des installateurs professionnels à fonctionner en dehors des bandes autorisées.

L’émetteur/récepteur exempt de licence contenu dans le présent appareil est conforme aux CNR d’Innovation, Sciences et Développement éco-
nomique Canada applicables aux appareils radio exempts de licence.
L’exploitation est autorisée aux deux conditions suivantes:
(1) l’appareil ne doit pas produire de brouillage, et
(2) l’appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d’en compromettre le fonctionnement.
Conformément à la réglementation d’Industrie Canada, le présent émetteur radio peut fonctionner avec une antenne d’un type et d’un gain
maximal (ou inférieur) approuvé pour l’émetteur par Industrie Canada. Dans le but de réduire les risques de brouillage radioélectrique à l’inten-
tion des autres utilisateurs, il faut choisir le type d’antenne et son gain de sorte que la puissance isotrope rayonnée équivalente (p.i.r.e.) ne
dépasse pas l’intensité nécessaire à l’établissement d’une communication satisfaisante.

INTRODUCTION
The instructions given below will make it simple and easy for you to start using your VOKKERO® Guardian Wireless Interface (WI) communica-
tion system.
All of the operations described are shared by the versions of the VOKKERO® Guardian WI product listed below:
VO8161B
Note: the reference number for your device can be found on the label located on the base of the device.
The system is made up of the following elements:
Wireless Interface box (WI)
A power supply
A radio antenna
A USB cable
The WI interface makes it possible to operate a VOKKERO® Guardian wireless conference system with a wired communication system. In
order to be able to configure the interface, you will need to link the equipment to a VOK-KERO® Guardian configurator/charger. When using
it for the first time, you will need to configure it in order to ensure that the system is compatible with the VOKKERO® Guardian conference
system.
All of the WI system’s operational parameters are controlled by the configurator. This lets you access the settings menu via a touchscreen.

3.2. Configuration with the VOKKERO® Guardian conference system
The WI interface must be configured at the same time as the other conference system equipment. If the WI interface is connected during the
quick config operation, it will then be configurated automatically and will be ready for use.
If a GUARDIAN terminal is placed on the first slot of the GUARDIAN configurator of the «Quick Settings» configuration pairing, the WI interface
will have a normal user role like any other GUARDIAN terminal, except the one placed on the first slot which will be the MASTER (M1).
If the first slot of the GUARDIAN configurator remains empty at the time of the «Quick Settings» configuration pairing, the WI interface will be
the MASTER (M1) of the VOKKERO network.
To find out how to launch the «Quick Settings» configuration pairing on the GUARDIAN configurator, please consult the VOKKERO® Guardian
conference system user manual.

4. AUDIO CONFIGURATION
4.1. Configuration with 4-wire Intercom systems
The WI interface is designed to be connected to a 4-wire intercom. Below you will find 2 configuration examples:
4.1.1. Clearcom 4-wire interface
• Connect a cable between the green connector of the clearcom interface and two XLR 3 pts male and female.
In order to identify the cabling, refer to the Clearcom IF4W4 user guide.
• Connect an XLR 3 pts cable (male/female) between the “OUT1” connector of the 4-wire interface system and the “IN” connector of the
Vokkero Guardian wireless interface.
• Connect an XLR 3 pts cable (male/female) between the “IN1” connector of the 4-wire interface system and the “OUT” connector of the
Vokkero Guardian wireless interface.
• Connect the Vokkero Guardian wireless Interface power cable to another power supply.

Adopted settings for the WI interface:
Out Audio Gain: 0dB
In Audio Gain: 12dB
Adopted settings for the GreenGo interface:
4-wire interface gain: 6db
Threshold: -45dB
4.2. Configuration with 2-wire Intercom systems
Operating the WI interface with a 2-wire Intercom system requires the use of a 2-wire/4-wire audio convertor.
Several material tests have been carried out, and we would recommend using the reference:
ALTAIR ALT4W2-200 with a CANFORD YL908 type “Y” cable
We would also recommend offsetting the antenna using an RF cable. Different lengths of RF cable or offset kit are available on request from our
sales department.
The list of different 2-wire Intercom references found below is not exhaustive and the settings for the 2-wire/4-wire convertor and the Guardian
WI Interface are given as an example.
