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 connes 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 oodlight “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.
