ETTING UP THE

TX238 T

RANSMITTER

NOTICE: THE RECHARGEABLE BATTERIES ARE SHIPPED IN A DIS-

CHARGED STATE. THE BATTERIES MUST BE CHARGED OVERNIGHT

BEFORE USING THE SOUNDPLUS™TV INFRARED SYSTEM.

The WIR TX238 Transmitter may be placed on top of a TV or

shelf. Place the TX238 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 dis-

tance is approximately 30 feet (9 m).

Ideally, the TX238 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 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 pres-

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

Any number of receivers may be used with the TX238

Transmitter, but use only one transmitter in a room at the same

time. Otherwise, interference will occur.

TV Microphone

If an RCAconnection is unavailable,

use the provided TV microphone to

pickup the sound source directly

from the TV loud speaker as shown

on right.

TX238 Transmitter (Rear View)

STEP 1: CONNECT THE TRANSMITTER POWER SUPPLY

Plug the Power Supply cord into the “DC 12V” jack 1on the

back of the TX238. Then plug the Power Supply into an AC

outlet. When the receiver is placed into the charging cradle built

into the top of the transmitter, the center charging indicator on

the front of the TX238 will turn on. When the spare battery is

plugged into the left or right battery charging port on the trans-

mitter,the corresponding charge indicator light will turn on.

STEP 2: CONNECT THE TRANSMITTER TO THE AUDIO SOURCE

Use the supplied red and white RCAaudio cables to connect the

TX238 Transmitter directly to the TV, VCR, or stereo “AUDIO

OUT” jacks. If your television does not have “AUDIO OUT”

jacks, you will need use the supplied TV microphone. See page

9for TV microphone instructions.

(HIGHEST AUDIO QUALITY)

Connect the RCAplugs from the TV or VCR

audio output into the LEFT and RIGHT RCA

jacks on the TX238 Transmitter 3.Next, slide the

stereo/mono switch 2on the TX238 Transmitter

to the stereo “??”position. Your transmitter is

now set for stereo operation.

STEP 3: SELECT STEREO OR MONO OPERATION

Compatible with:

RX237

-or-

RX238

STEREO OPERATION:

Note: Choose 1of 3 transmitter setup options below and on

page 9. Verify receiver compatibility on left.

Important : If your system is packaged with the WIR RX239

(neckloop) Receiver, you must setup the WIR TX238

Transmitter to operate in 2.3 MHz (mono) mode. See 2.3 MHz

(mono) instructions on page 9. The WIR RX239 (neckloop)

Receiver will NOT work while the transmitter is in stereo or

2.8 MHz mode.

If your system is packaged with the WIR RX237 or WIR RX238

Receiver, you can choose to operate the WIR TX238 in stereo OR

mono (2.3 or 2.8 MHz) operation. For the highest quality, stereo is

the recommended mode of operation.

STEP 2 (CONTINUED):

NOTE: Some televisions have FIXED output and others have

VARIABLE output. If available, FIXED output should be

selected. Consult your television manual for more information.

“Fixed” output means the volume on the television will not

change when the volume is increased, decreased, or muted.

“Variable” output means the volume on the television will

change when it is increased, decreased, or muted. If variable

output is the only output available on your television, we recom-

mend using the supplied TV microphone. See page 9 for TV

microphone instructions.

STEP 3 (CONTINUED):

If an RCA connection is unavailable,use the provided

TV MICROPHONE 5to pickup the desired sound source.

Plug in the microphone into the Mic Jack on the rear of the

TX238 Transmitter 4.Use the velcro strip supplied to attach

the microphone near the loudspeaker 4of your TV or stereo.

The microphone 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.

Connect the LEFT RCAplug from the TV or

VCR audio output into the LEFT RCAjack on the

TX238 Transmitter 3(the right jack should be

left unplugged). Next, slide the stereo/mono

switch to the “ o”mono position 2.The trans-

mitter is now set for 2.3 MHz operation.

Connect the LEFT RCAplug from the TV or VCR

speaker output into the RIGHT RCAjack on the

TX238 Transmitter 3(the left jack should be left

unplugged). Next, slide the stereo/mono switch 2

to the “ o”mono position. The transmitter is now

set for 2.8 MHz operation.

SETTING UP THE RX237 RECEIVER

STEP 1: INSTALL THE RECEIVER BATTERIES

Insert the rechargeable battery into the bottom of the RX237 Receiver

(see page 12). Place the receiver into the charger cradle built into the

top of the TX238 Transmitter and let charge overnight.The spare bat-

tery can be plugged into the charging port located on either side of the

transmitter. By keeping the spare battery charged, you can easily swap

batteries when the one in use runs out and always have a fresh battery

ready. A fully charged battery will operate the receiver for approxi-

mately 6 hours depending on the volume setting. The battery should

be changed when you notice the sound getting weak and noisy. the

batteries may be left charging when not in use.

STEP 2: USING THE WIR RX237 RECEIVER

The RX237 will automatically configure itself for stereo or mono

(2.3 or 2.8 MHz) operation depending on the setup chosen for the

TX238 Transmitter.

Before you use the system, double check to make sure the WIR

TX238 Transmitter’s power supply is plugged in. Make sure the TV,

stereo, or audio source is turned ON. Make sure the receiver’s battery

is fully charged.

To Use the Receiver:

1. First, place the lanyard on the receiver around your neck.

IMPORTANT: a dual detector infrared “eye” is located in the

front of the receiver. Do not cover it up or you will lose recep-

tion. Make surethe “SOUND PLUS” lettering is facing away

from you when you put the receiver on.

2. Next, plug in an earphone, headphone, or neckloop with 3.5mm

plug into the jack on the bottom of the RX237 receiver (see drawing

on page 12). Note : The RX237 turns ON automatically when you

plug in the earphone/headphone into the jack, and turns OFF when

you remove the earphone/headphone from the jack.

3. Rotate the volume control to a comfortable listening level. Note:

If you are using a neckloop with the RX237, turn the volume control

to “2,” or about half of full volume. Then, turn the switch on your

hearing aid to the “T” position and adjust the volume to a comfort-

able listening level. If the sound is weak, increase the volume on the

RX237 Receiver, then on your hearing aid.
