Setting up the TX240 Transmitter
NOTICE: THE RECHARGEABLE BATTERIES ARE SHIPPED IN A DISCHARGED STATE. THE BATTERIES MUST BE CHARGED OVERNIGHT
BEFORE USING THE TV TALKER INFRARED SYSTEM.
The WIR TX240 Transmitter may be placed on top of a TV or shelf. Place
the TX240 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 TX240 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 present. Closing drapes or blinds
will help if sunlight is a problem.
Any number of receivers may be used with the TX240 Transmitter, but use
only one transmitter in a room at the same time. Otherwise, interference
will occur.

❺ TV Microphone
If an RCA connection is unavailable, use the
provided TV microphone to pickup the sound
source directly from the TV loud speaker as
shown on left.
Step 1: Connect the Transmitter Power Supply
Plug the Power Supply cord into the “DC 12V” jack on the back of the
TX240. 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 TX240 will turn on. When the
spare battery is plugged into the left or right battery charging port on the
transmitter, the corresponding charge indicator light will turn on.
Step 2: Connect the Transmitter to the Audio Source
Use the supplied red and white RCA audio cables to connect the TX240
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 9 for TV microphone instructions.

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 recommend using
the supplied TV microphone. See page 9 for TV microphone
instructions.
Step 3: Select Stereo or Mono Operation
Note: Choose 1 of 3 transmitter setup options below and on page
9. Verify receiver compatibility on left.
For the highest quality, stereo is the recommended mode of operation.

Setting up the RX240 Receiver
Step 1: Install the Receiver Batteries
Insert the rechargeable battery into the bottom of the RX240 Receiver
(see page 11). Place the receiver into the charger cradle built into the top
of the TX240 Transmitter and let charge overnight. The spare battery 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 approximately 7 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 RX240 Receiver
The RX240 will automatically configure itself for stereo or mono (2.3 or 2.8
MHz) operation depending on the setup chosen for the TX240 Transmitter.
To use the system, first check to make sure your TV or audio source is
turned ON. Make sure the receiver battery is fully charged. The RX240
Receiver has an automatic on/off function. When you put the receiver on,
it turns on. When you take the receiver off, it turns off. Rotate the volume
control to adjust the volume to a comfortable level.
IMPORTANT: A dual detector infrared “eye” is located in the front
of the receiver. Do not cover it up or you will lose reception. Make
sure the “TV TALKER” lettering is facing away from you when you
put the receiver on.
Return the receiver to the charger when it is not in use.
Additional Receiver Adjustments
Balance Control: Use a small screwdriver to adjust the loudness balance
between the left and right earphones. See page 11.

Setting up the RX250 (Neckloop) Receiver
Step 1: Install the Receiver Batteries
Insert the Rechargeable battery into the bottom of the RX250 Receiver
(see drawing on page 13). Place the receiver into the charger cradle
built into the top of the TX240 Transmitter and let charge overnight. The
spare battery 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
approximately 7 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 RX250 Receiver
The RX250 Receiver magnetically transfers the audio from the TX240
Transmitter into a hearing aid equipped with a telephone coil (T-coil), or
can be used with stereo headphones.
Before you use the receiver, double check to make sure the WIR TX240
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. RX250 must be turned off when the battery is being recharged.
To use the Receiver:
1. First, place the neckloop on the receiver around your neck.
Important: A dual detector infrared “eye” is located on the front
of the receiver. Do not cover it up or you will lose reception. Make
sure that “TV TALKER” lettering is facing away from you when
you put the receiver on.
2. Turn the receiver ON by sliding the switch on the back to the
“ON” position.
3. Turn the switch on your hearing aid to the “T” position and
adjust the volume for comfortable listening when using induction
loop feature.
4. If the sound is weak, increase the volume on the Williams Sound
unit, then on your hearing aid.

make sure that its front panel is facing the receiver.
5.Make sure that the receiver has a fully charged battery.
6.Make sure you are not covering the infrared “eye.” Remove any
objects obstructing the line between the TX240 Transmitter and the
receiver. The “TV TALKER” label should be facing towards the TV
while you listen.
7.If you are using the RX240 or RX250 Receiver and getting static or
hiss: Try operating the TX240 Transmitter in MONO (2.3 MHz or 2.8
MHz) mode. See instructions on page 8.
8.If you are operating the TX240 Transmitter in MONO (2.3 MHz or 2.8
MHz) mode and getting noise or hiss in the receiver: For 2.3 MHz
operation, check to make sure you are only using the left RCA jack
on the TX240 Transmitter. For 2.8 MHz operation: make sure you are
only using the right RCA jack on the TX240 Transmitter.
9.If you are using the TV microphone and not getting a signal, try
turning up the TV volume up slightly. Also, try positioning the TV mic
directly over the TV speaker.
