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 trans-
mitter 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 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.
