The WIR TX7 Transmitter has an adjustable base that allows it to be mounted on a wall or
cabinet, or placed on top of a TV or shelf. If you will be mounting it on a wall, use the keyed
mounting holes on the bottom of the transmitter.
The two horizontal mounting holes are 2-1/4" (5.7 cm) apart and the two vertical holes are
3" (7.6 cm) apart.
Place the TX7 Transmitter where it is clearly visible from your listening position. (See Fig 1.)
Infrared light behaves like visible light, so it is blocked by solid objects. This confines the sig-
nal 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).
