Important Safety Instructions

1. Follow all instructions.

2. Do not block any ventilation openings.

3. Do not place the apparatus on an unstable surface, near water or heat source.

4. Use only the power cord that comes with the apparatus. Use of another cord may result in fire

or electric shock.

5. Use only the type of power source indicated on the apparatus and always supply power directly

from a standard domestic electric outlet with the AC power cord that meets the relevant local

safety standards.

6. Connect all equipment to properly grounded power outlets. Avoid using outlets on the same

circuit as photocopiers or air control systems that regularly switch on and off.

7. Protect the power cord from being walked on or pinched.

8. Unplug the apparatus during lightning storms or when unused for long periods of time.

9. Refer all servicing to qualified service personnel. Servicing is required when the apparatus has

been damaged in any way, such as power-supply cord or plug is damaged, liquid has been

spilled or objects have fallen into the unit, the apparatus has been exposed to rain or moisture,

does not operate normally, or has been dropped.

General Descript ion

GONSIN TC-902/904/906/908 infrared system is designed to offer simultaneous interpretation

and wireless audio distribution for up to 1, 3, 5 or 7 different languages plus the floor language

using the proven, state-of-the-art infrared light transmission technology.

As the central element of the system, the infrared transmitter interfaces with either analog or

digital discussion system, connects to the interpreter consoles and the infrared radiators which

transmit audio signals to wireless multi-channel receivers for the delegates to hear the language

of their choice via personal earphones.

The system operates in the higher 2 MHz to 6 MHz frequency band, immune to distortion from

hall lighting and free from outside radio frequency interference.

As infrared signals do not pass through walls and ceilings, the system is secure to use. Multiple

applications can run simultaneous in different rooms without interfering with one another.

The system complies with the relevant ISO, IEC, CE standards/requirements and is ideally suited

for use in business and government conferences, international conventions and other multilingual

applications.

Typical Applications

Convention centers Parliament chambers Courtrooms

Boardrooms City councils Classrooms

Auditoriums Theatres Churches

System Test ing

After all the system components are connected, make sure the TEST switch is OFF on the transmitters

rear panel. Turn on power for the transmitter and radiators, and then turn on the TEST switch. The

level indicators on the transmitters front panel will light up. Listen to the test signal for every channel

via an infrared receiver. Walk about the conference venue. If there is any blind area, adjust the

radiators mounting angle or HIGH/LOW output level. After the testing is finished, turn the TEST

switch to OFF position.

Turn on the interpreter microphone, conference system central unit and other audio equipment, and

then choose an output channel to see if the signal can be heard via the receiver.

Please note: 1) The receivers should be used at least 5 meters away from any radiator. 2) The floor

signal should be connected to the CH0 input socket on the transmitter rear panel. 3) The transmitter

and the radiators should use an external power supply with a ground.
