ETTING UP THE

TX295 T

RANSMITTER

The WIR TX295 Transmitter may be placed on top of a TV or

shelf. Place the TX295 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 any-

thing except glass. The maximum operating distance is approxi-

mately 30 feet (9 m).

Ideally, the TX295 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 TX295

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

time. Otherwise, interference will occur.

STEP 1: CONNECT THE TRANSMITTER POWER SUPPLY

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

the TX295. Then plug the Power Supply into an AC outlet.

STEP 2: SELECT AN OPERATING FREQUNCY FOR THE TX295 TRANSMITTER

To use the TX295 transmitter with the RX3 receiver, you must

first setup the transmitter to operate in 95 kHz mode. Referring to

the diagram above, slide the Stereo/Mono Selection Switch to the

“L” Left position for 95 kHz. The transmitter is now setup to

operate with the RX3 receiver.

STEP 3: CONNECT THE TRANSMITTER TO THE AUDIO SOURCE

If you are using the TV Microphone, plug it into the “Mic” jack

on the TX295 as shown. Use the Velcro strip supplied to attach the

microphone near the loudspeaker of your TV. 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.

To use the supplied Audio Cable to connect the TX295 Transmitter

directly to TV, VCR, or other equipment output jacks:

Connect the LEFT RCA plug from the TV (or VCR) speaker

output into the LEFT RCA jack on the TX295 transmitter.

Remember,the Stereo/Mono Selection Switch must be in the

“L” Left position to transmit in 95 kHz!

When the Audio Inputs are used, the Mic input is automatically

disabled.

NOTE: The TX295 has an automatic shut-off feature that turns

the Transmitter off 90 seconds after the audio signal is no longer

present.

ETTING UP THE

WIR RX3 R

ECEIVER

1. INSTALL THE RECEIVER BATTERIES

Open the Battery Compartment on the RX3 Receiver and install a

9V carbon zinc battery. Be sure to insert the battery “plus” and

“minus” terminals correctly as shown on the yellow battery pull

tab. DO NOT force the battery in backwards. If you are using a

rechargeable, NiMH battery, charge the battery for 12–14 hours

before using the receiver.

Make sure the Receiver Volume Control Switch (Shown in fig-

ure below) is turned OFF while charging.

2. PLUG IN THE EARPHONE OR HEADPHONE.

Next, plug the earphone or headphone into the jack on top of the

receiver

3. USING THE RECEIVER

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 RX3. Do not cover it up or you will

lose reception.

Be sureto turn the Receiver OFF when it is not in use.

1. Read through the manual and user guide carefully to verify

proper setup and installation of your system.

2. Make sure that your television is plugged in and turned on.

3. Make sure that the TX295 Transmitter is plugged in and cor-

rectly connected to the TV or VCR’s audio output.

4. Make sure the TX295 is operating on 95 kHz, not stereo or 250

kHz mode. See Step 2 in Setting up the TX295 Transmitter.

5. If you’re using the TV Mic and not getting a signal: 1) Be sure

the audio cable is not plugged into the TX295; 2) Try turning

the TV volume up slightly; 3) Try positioning the TV mic

directly over the TV speaker.

6. Make sure that the RX3 Receiver has a working battery.

7. Make sure you are not covering the RX3’s infrared "eye.”

Remove any objects obstructing the line between the TX295

Transmitter and the RX3 Receiver.

8. If you’ve installed the TX295 Transmitter other than on

top of the TV, make sure that its front panel is facing the

RX3 Receiver.
