Introduction
Thank you for purchasing the InfraLight Wireless listening system. The system
allows you to listen more clearly to your TV, Radio or HiFi without any need for
trailing wires. It uses Infrared technology, similar to remote controls, to transmit
sound from your TV or other audio equipment to a headset or neckloop receiver.
Before using the system, please read these instructions to benefit from all the
capabilities of the system and give you many hours of reliable listening performance.
The system consists of two parts; a transmitter to pick up sound from your TV or
HiFi and a receiver powered by a rechargeable battery. A headset receiver is for
people without a hearing aid and a neckloop receiver is for people who want to
use the ‘T’ facility of their hearing aid.
The system is delivered with a connection kit to allow you to connect to most
modern audio equipment. An optional microphone can be used where direct
connection is not possible.
More than one listener can use the same transmitter. Receivers of either type can
be used at the same time. The system can charge up to three batteries at the
same time.

Setting up
Place the transmitter in a suitable position near to your TV or HiFi. Make sure that
the front is placed so that it can be seen by anyone who wants to receive infrared
signals.
To obtain the best quality sound through your system use the red/white RCA
phono connectors on the transmitter with the lead supplied to directly connect to
your TV.
If your TV or HiFi uses similar red/white RCA phono connectors to output sound
then connect to these.
YoumayneedtorefertoinstructionsforTVtocongurethesocketstoprovide
sound output if you get no sound from them.
If your TV does not use RCA phono connectors to output sound then you could
use the SCART or jack adaptors accordingly to suit your equipment.
If you use the jack adaptor you may find that using a headphone socket may turn
off internal speakers for other users.
An optional microphone can be used to pick up the sound from your TV, allow
people to speak to you through the system or to monitor other sounds e.g.
telephone or door bell.
Mono/Stereo switch. Normally set to “stereo”. If you connect to a mono audio
source then switch to “mono” otherwise sound will only be heard in one ear
piece.
Plug the power supply into the transmitter and a mains socket.
Place receiver in charging cradle and allow the batteries to charge for 14 hours
before first use.
Rechargeable Batteries
The system only uses purpose-made batteries for the receivers. The system is
supplied with one battery. Additional batteries may be purchased separately.
This may be found in a packet or installed in the receiver. Blanking pieces are
inserted in the charging sockets of the transmitter to prevent damage to the
transmitter; these may be removed to charge one or two spare batteries. The
blanking piece may look like a battery but it has no metal contacts.

Before wearing the receiver adjust its’ volume control to minimum.
Receivers should be worn so that the InfraLight logo faces towards the
transmitter.
The transmitter power should not be switched off otherwise the batteries may not
be fully charged when required.

Rechargeable batteries and charging
Youcanexpectupto10hourslisteningfromafullychargedbattery.However
this may be reduced according to the volume setting of the receiver and the type
of programme being watched.
If, whilst listening, the sound stops or the sound quality becomes noisy or
distorted the receiver battery has become discharged and will need charging
before further use.
Youmaywishtopurchaseasecondbatterytoincreaseyourlisteningtime.A
second or third battery may be placed in either of the charging sockets on the

your battery becomes discharged whilst listening you can simply swap batteries
to continue listening. A flat battery will be recharged in about 14 hours.
Red indicator lights will show in the front of the transmitter if a battery is being

The mains power to the transmitter must be left on for the batteries to recharge.
The charging control lights show red at all times when charging and do not
change colour. They only indicate the presence of a battery in the charging
position and do not indicate that a battery is being charged. Batteries normally
take about 14 hours to reach full charge.

Maximising Battery life
Eachbatterypackcontains2NiMHrechargeablecells.Allrechargeable
batteries have a limited life and do not last for ever. Full battery capacity may
not be reached until 4-5 charge/discharge cycles have occurred. These battery
packs are designed to be recharged at least 500 times.
If you can fully discharge the battery through use before recharging then
youwillgetthemaximumlifefromthebattery.Ifpartiallychargedbatteries
are recharged this will shorten the overall life of the battery. All rechargeable
batteries degrade over time which means that their capacity will naturally
decrease with regular use.
If you are unsure whether a receiver battery is fully discharged before placing in
the charging cradle then use the receiver until the sound disappears or becomes
distorted then either recharge the battery pack or, if available, simply swap the
battery pack for a fully charged spare battery from the transmitter charging
socket.
Remember to switch the power off to the transmitter and remove the batteries
from transmitter and receivers when not using the system for a long period of
time.
