S 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.

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.

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.
