Williams Sound WIR 135 Manual de usuario

VERVIEW

Thank you for purchasing the WIR 135 Listening System from Williams Sound Corp. Anyone

needing auditory assistance to overcome background noise, reverberation, or distance from the

sound source can benefit from the WIR 135.

You can use the WIR 135 for listening to the TV or other audio equipment, or for hearing assis-

tance in conference rooms. You can also use your RX8 Receiver in most facilities which have

an infrared transmitter operating on 95 kHz, such as theaters, cinemas, or churches.

RANSMITTER

The WIR TX95 Transmitter may be placed on top of a TV or shelf. Place the TX95 Transmitter where it is

clearly visible from your listening position.

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 approximately 30 feet (9 m).

Ideally, the TX95 Transmitter should be at ear-level height or above. The infrared light pattern is

much like a floodlight “cone” as it leaves the transmitter, with the best reception inside the cone.

Sunlight can cause infrared interference by reducing the operating distance. Thus, the system can-

not be used outdoors and may not work properly inside if a lot of direct sunlight is present.

Closing drapes or blinds will help if sunlight is a problem.

Any number of receivers may be used with the TX95 Transmitter, but use only one transmitter

in a room at the same time. Otherwise, interference between transmitters will occur.

OURCE

You may also use the Audio Cable supplied to connect the TX95 Transmitter directly to TV,

VCR, or other equipment output jacks . The WIR 135 is a mono system, so the Left and Right

inputs are mixed together. The Left or Right input jack may be used with a mono sound source.

When the Audio Inputs are used, the Mic input is disabled.

If you are using the TV Microphone , plug it into the “Mic” jack on the TX95 as shown. Use

the Velcro strip supplied to attach the microphone near the loudspeaker of your TV. The micro-

phone will allow you to play the TV at lower volume for other listeners and will pick up other

important sounds like the telephone or doorbell ringing.

The TX95 has an automatic shut-off feature that turns the Transmitter off several minutes after

the audio signal is no longer present.

Rotate the Receiver Volume Control knob 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 RX8. Do not

cover it up or you will lose reception.

Be sureto turn the Receiver OFF when it is

not in use.

ASE OF

IFFICULTY

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 TX95 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 sig-

nal: 1) Be sure the audio cable is not plugged

into the TX95; 2) Try turning the TV volume up

slightly; 3) Try positioning the TV mic directly

over the TV speaker.

4. Make sure that the RX8 Receiver has a working

battery.

5. Make sure you are not covering the RX8’s

infrared “eye.” Remove any objects obstructing

the line between the TX95 Transmitter and the

RX8 Receiver.

6. If you’ve installed the TX95 Transmitter other

than on top of the TV, make sure that its front

panel is facing the RX8 Receiver.

7. If the system still does not function, call your

Williams Sound Dealer.
