About This Manual
Throughout this guide we use different icons to designate different types of information:
This is a note. A note gives additional information, such as the meaning of the color of the LEDs. A
note also provides information that may only be applicable to some situations.
This is a tip. A tip gives you an alternative way to do a particular step or procedure, or lets you know
of an option that you may find helpful.
This indicates that something is very important. Important information is something that you need to
do in order to accomplish a certain task.
This provides safety precaution information, that is, information that you need to be careful about to
prevent potential problems when using our systems.

ABOUT LINGUA IR
Concept And Design
Lingua Infrared (IR) is Televic Conference's wireless solution for language distribution using infrared. You
can combine this system with Plixus engines or another third-party system to feed the floor and interpreter
audio to the Lingua IR. Link this audio source to the Lingua IR transmitter through a Dante™ connection.
The transmitter will send the audio signal to the radiators inside the room. The radiator will then send the
audio signal as infrared radiation to the receivers present in the room. These will then convert the radiation
back into an audio signal. Finally, with the receiver the participant can use which languages they wish to
hear.

feed audio into the infrared system. Participants present in the room can listen to the audio they want using the
receivers that pick up the infrared radiation.

Lingua IR consists out of four parts:
Lingua T (transmitter): accepts the audio signal from the conference system (for example
Plixus) and transmits the signal to the radiator(s). By default you can transmit up to 6 channels,
however additional licenses are available to transmit 12 (Lingua L12) or 40 channels (Lingua
L40).
Lingua RAD_H (radiator): distributes the signal throughout the conference venue.
Lingua Rx (receiver): allows attendees to select the language they want to hear the speaker
in. Three variants are available to receive 6, 12 or 40 channels.
Lingua CHC (charging case): case to charge and transport receivers in.

Read this before using the equipement.

SAFETY INSTRUCTIONS
The safety instructions contain general safety guidelines that integrators, installers, operators, end users,
and anyone else who installs or uses Televic Conference material is required to read and follow at all times.
Safety
All Televic Conference systems are state of the art devices and have been designed to meet all quality
standards. Nevertheless, the individual components of the conference system can cause danger for persons
and material assets if
the conference system is not used as intended,
the conference system is set up by personnel not familiar with the safety regulations,
the conference system is converted or altered incorrectly,
the safety instructions are not observed.

dealer or local power company. For products intended to operate from battery power, or other
sources, refer to the operating instructions.
13. Power Lines. An outdoor system should not be located in the vicinity of overhead power lines or
other electric light or power circuits, or where it can fall into such power lines or circuits. When
installing an outdoor system, extreme care should be taken to keep from touching such power lines
or circuits, as contact with them might be fatal. U.S.A. models only - refer to the National Electrical
Code Article 820 regarding installation of CATV systems.
14. Grounding or Polarization. Do not defeat the safety purpose of the polarized or ground-type
plug. A polarized plug has two blades with one wider than the other. A grounding type plug has two
blades and a third grounding prong. The wider blade or the third prong are provided for your safety.
SAF ETY INSTR UCTIO NS 14

If the provided plug does not fit into your outlet, consult an electrician for replacement of the
obsolete outlet.
15. Power-Cord Protection. Power-supply cords should be routed to that they are not likely to be

plug, convenience receptacles, and the point where they exit from the product.
16. Lightning. For added protection for this product during a lightning storm, or when it is left
unattended and unused for long periods of time, unplug it from the wall outlet. This will prevent
damage to the product due to lightning and power-line surges. (Not applicable when special
functions are to be maintained, such as evacuation systems.)
17. Overloading. Do not overload wall outlets, extension cords or integral convenience receptacles as
this can result in a risk of fire or electric shock.
18. Object and Liquid Entry. Never push objects of any kind into this product through openings as
they may touch dangerous voltage points or short-out parts that could result in a fire or electric
shock. Never spill liquid of any kind on the product.

replacement parts specified by the manufacturer or have the same characteristics as the original
part. Unauthorized substitutions may result in fire, electric shock, or other hazards.
24. Safety Check. Upon completion of any service or repairs to this product, ask the service technician
to perform safety checks to determine that the product is in proper operating condition.
25. Coax Grounding. If an outside cable system is connected to the apparatus, be sure the cable
system is grounded. U.S.A. models only: Section 810 of the National Electrical Code, ANSI/NFPA
No.70-1981, provides information with respect to proper grounding of the mount and supporting
structure, grounding of the coax to a discharge apparatus, size of grounding conductors, location of
discharge unit, connection to grounding electrodes, and requirements for the grounding electrode.
26. Eye exposure. Beware of permanent eye damage due to the infrared radiation. Permanent
exposure is allowed at a distance of 50cm (E=100W/m² limit according to IEC62471 2006-2007
first edition). At distances below 10 cm (=for servicing, installation testing), limit is reached after 20
to 30 seconds. Take precautions : cover the LEDs during servicing/testing and limit the exposure
time. Avoid looking directly into the LEDs and limit the exposure time. At distances between 10 to
50 cm : avoid looking directly into the LEDs and limit the exposure time.
