WIR 150 Listening System Instructions

Model WIR TX5 Transmitter, WIR RX1 Receiver

OVERVIEW

Thank you for purchasing the WIR 150 Listening

System from Williams Sound Corporation.

Anyone needing auditory assistance to overcome

background noise, reverberation, or distance from

the sound source can benefit from the WIR 150.

You can use the WIR 150 for listening to the TV

or other audio equipment, or for hearing assis-

tance in conference rooms. You can also use your

RX1 Receiver in most facilities which have an

infrared transmitter operating on 95 kHz, such as

theaters, cinemas, or churches.

If at anytime you have problems with the sys-

tem, do not hesitate to call us toll-free at 1-

800-843-3544.

SYSTEM COMPONENTS

The WIR 150 Listening System includes the fol-

lowing elements.

1. TX5 Transmitter

• AC to DC Adaptor

• TV Microphone

• RCA Plug Adaptor

• Audio Cable With Two 3.5 mm Plugs

2. RX1 Receiver

• AAA Batteries

1. SET UPTHE TRANSMITTER

The WIR TX5 Transmitter has an adjustable base

that allows it to be mounted on a wall or cabinet,

or placed on top of a TV or shelf. If you will be

mounting it on a wall, use the keyed mounting

holes on the bottom of the transmitter. The two

horizontal mounting holes are 2-1/4" (5.8cm)

apart and the two vertical holes are 3" (7.5cm)

apart.

FIGURE 2: TX5 TRANSMITTER (FRONT VIEW)

Place the Transmitter where it is clearly visible

from your listening position. An example is

shown in Figure 4. Infrared light behaves like

visible light, so it is blocked by solid objects.

This confines the signal to the room where the

transmitter is located. The Transmitter cannot be

placed inside or behind anything except glass.

The maximum operating distance is approximate-

ly 30 feet (9m).

Ideally, the TX5 Transmitter should be at ear-

level height or above. The infrared light pattern is

cone-shaped as it leaves the Transmitter, as

shown in Figure 5. The best reception is inside

the cone. Sunlight can cause infrared interference

in the form of a buzz, hiss, or static. Thus, the

system cannot be used outdoors and may not

work properly inside if a lot of direct sunlight is

present. Closing drapes or blinds will help if sun-

light is a problem.

Any number of Receivers may be used with the

TX5 Transmitter, but use only one Transmitter in

a room at the same time. Otherwise, interference

will occur.

2. CONNECT THE TRANSMITTER

POWER SUPPLY

Plug the AC to DC Adaptor cord into the “DC

12V” jack on the base of the TX5 Transmitter.

Then plug the Adaptor into an outlet. The red

power indicator will light.

3. CONNECT THE TRANSMITTER TO THE AUDIO

SOURCE

Plug the blue-banded end of the Audio Cable into

the TV Microphone as shown in Figure 1. The

microphone has a velcro clip that can be attached

near the loudspeaker of your TV.

The Audio Cable’s blue end can also be connect-

ed directly into an audio output from a VCR or

TV with the RCA Plug Adaptor supplied.

The TX5 Transmitter features an Automatic

Level Control to adjust for different audio signal

levels and to maintain a comfortable listening

level.

Note: When using the RCA Plug Adaptor, make

sure to connect the adaptor to the Audio Cable’s

blue-banded plug. This will ensure a good electri-

cal contact. See Figure 1.

4. INSTALL THE RECEIVER BATTERIES

Open the Battery Compartment on the RX1 and

install two (2) AAA alkaline batteries. Be sure to

insert the batteries’ “+” and “–” terminals correct-

ly. DO NOT force the batteries in backwards. If

you use rechargeable batteries, DO NOT attempt

to charge them within the receiver.

5. USING THE RECEIVER

Inside the Battery Compartment is a Hi–Lo

Volume Switch. Set this switch to Hi. Rotate the

Receiver Volume Control to turn the receiver on

and adjust the volume to a comfortable level.

Make sure your TV or audio source is turned on.

You should be able to hear the signal from the

Transmitter in the Receiver. The infrared receiver

“eye” is located on the front of the RX1. Do not

cover it up or you will lose reception.

Be sure to turn the Receiver OFF when it is

not in use.

INCASE OF DIFFICULTY

If the system does not seem to be functioning:

1. Make sure that your television is plugged in

and turned on.

2. Make sure that the TX5 Transmitter is

plugged in and correctly connected to the

TV or VCR’s audio output.

3. If you’re using the TV Mic and not getting a

signal, try turning the TV volume up slight-

ly. Also, try positioning the TV Mic directly

over the TV speaker.

4. Make sure that the RX1 Receiver has work-

ing batteries.

5. Make sure you are not covering the RX1’s

infrared “eye”. Remove any objects

obstructing the line between the TX5

Transmitter and the RX1 Receiver.

6. If you’ve installed the TX5 Transmitter

other than on top of the TV, make sure that

its front panel is facing the RX1 Receiver.

7. If the system still does not function, call

Williams Sound Corporation at

1-800-843-3544.
