Overview
Thank you for purchasing the WIR 100 Listening
System from Williams Sound Corp. Anyone needing
auditory assistance to overcome background noise,
reverberation, or distance from the sound source can
benefit from the WIR 100.
You can use the WIR 100 for listening to the TV or
other audio equipment, or for hearing assistance in
conference rooms. You can also use your RX4
Receiver in most facilities which have an infrared
transmitter operating on 95 kHz, such as theaters,
cinemas, or churches.
If at anytime you have problems with the system,
don’t hesitate to call us toll-free at 1-800-843-3544.
