User Manual

INTRODUCTION

TV SOUND® is a Personal Sound Amplifier which can be used by people with impaired hearing or by people with normal hearing. It can be used to listen to TV or other audio equipment without disturbing others. It uses a 2.3MHz Infra-red (IR) system.

WARNING: This product can produce high sound pressure levels in order to assist people with impaired hearing. Excessive sound pressure levels can cause hearing damage so it is recommended to initially set the volume to a low level and gradually increase it to a comfortable level.

If your TV set has only digital audio output terminals (optical or coaxial) it will be necessary to obtain a Digital to Analog (DAC) converter box and connect as described elsewhere in this manual.

INSTALLATION

Page 3

1. Connect the power supply as shown in the diagram.

2. The transmitter/charger must be connected to the audio OUTPUT sockets of the

TV, audio equipment, cable or satellite box, DVD or VCR player, etc. When an

RCA type cable is used the outputs jacks are red and white. Refer to the diagram.

A Scart adapter (not included) may also be used. Use only the red and white

terminals.

NOTE: If the system is connected to a cable or satellite box and to a DVD or VCR

player it is necessary to turn off the device which is not in use at the time. When

using the DVD or VCR player turn off the cable or satellite box. When watching

TV turn off the DVD and VCR player.

3. Connecting to a digital converter box (DAC).

Connect the digital audio output from the TV or audio device to the DAC using

an appropriate cable (optical or coaxial cable). Then use the supplied RCA type

cable to connect from the red and white output terminals of the DAC to the audio

input socket of the transmitter/charger.

NOTE: If you wish to use the system to listen to TV while the TV sound is muted

so as not to disturb others the TV audio output must be set to FIXED. Refer to the

user manual of your TV for instructions as to how to set to FIXED.

POSITIONING

The infra-red (IR) signals need a direct line-of-sight connection between the

transmitter and the headset. Position the transmitter such that there is a direct

line-of-sight connection with the headset when in use. The IR signals may be

blocked by objects such as walls, doors, furniture, newspapers, books, etc. The IR

diodes are lit during use.

NOTE: When there is no audio input to the transmitter/charge transmission is

turned off automatically and is resumed automatically when audio signal is

restored.

OPERATION

1. Make sure that the transmitter/charger is correctly connected to the mains supply

using the supplied adapter.

2. Put on the headset such that the front (silkscreened) part of the headset is facing

the transmitter.

3. Turn on the headset using the ON/OFF/VOLUME control and adjust the volume.

4. When you are finished using the system carefully place the headset in the

charging cradle making sure that it fits snugly in the cradle. Check that the charging

light turns on.

SAFETY, CARE AND MAINTENANCE

• The system which is designed to operate from a 100-240V AC supply does

not have an integral ON/OFF switch. To disconnect the power switch the

mains power point switch to OFF or unplug the power supply (AC-DC

adapter).

• Clean the headset and ear tips regularly ----- use a damp cloth for the

headset and warm water and a mild detergent for the ear tips (after removal

from the headset).

• Keep away from heat sources such as hot-plates, and heat generating

appliances.
