ETTING UP THE

TX295 T

RANSMITTER

NOTICE: THE RECHARGEABLE BATTERIES ARE SHIPPED IN A DISCHARGED

STATE. THE BATTERIES MUST BE CHARGED OVERNIGHT BEFORE USING THE

WIR 952 SYSTEM.

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.

SETTING UP THE RX295 RECEIVER

STEP 1: INSTALL THE RECEIVER BATTERIES

Insert the Rechargeable battery into the bottom of the RX295

Receiver (see page 10). Place the Receiver into the charger cradle

built into the top of the TX295 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 oper-

ate the receiver for approximately 6 hours, depending on the volume

setting. The battery should be changed when you notice the sound

getting weak and noisy or if the Receiver indicator light is not on.

The batteries may be left charging when not in use.

STEP 2: USING THE WIR RX295 RECEIVER

Choose between stereo, 95 kHz or 250 kHz (mono) operation. Slide

the channel selector switch to the position for stereo. For 95 kHz

operation, slide the channel selector switch to the “A” position

(mono). For 250 kHz operation, slide the channel selector switch to

the “B” position (mono). IMPORTANT:Make sure you are operating

on the same frequency as the TX295 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

RX295 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.

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

the “SOUND PLUS” 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.

Tone Controls: Use a small screwdriver to adjust the tone for the

left and right earphones.

Ear Cushions: Replacement Ear Cushions are available from your

Williams Sound dealer, Part Number EAR 031.
