System Overview
Thank you for purchasing the Hearing Helper

T800 transmitter from Williams
Sound. This wide-band FM transmitter operates on the 863 MHz bandwidth
and connects directly to your facility’s sound system; alternatively, it can used
with a microphone as a stand-alone system. The T800 is designed for use
with the optional R863 FM receiver to provide hearing assistance or language
interpretation to a listening audience.
The T800 transmitter operates much like an FM radio station. First, the
transmitter receives the audio from the facility’s mic or sound system,
then the transmitter broadcasts the audio as an FM signal to the listening
audience. Listeners use the R863 receivers equipped with headsets or
earphones to pick up the FM broadcast up to 400 feet away.
To avoid difficulties, please read through these instructions as you begin
to use the system. Then save the manual for questions that arise as you
continue to use your system. If at any time you are having problems with this
product, please contact Williams Sound for assistance: +1 952 943 2252.
