PFM T31 Transmitter

Instructions For Use & Care

Thank you for purchasing the PFM T31 transmitter from Williams Sound. The T31 trans­mitter is designed to operate with a wide-band FM, 72–76 MHz receiver. For optimal per­formance, we recommend using the Williams Sound R31 or R32 receiver. Please call a
Williams Sound representative for more information: 800-843-3544.
How it Works: The T31 transmitter uses a microphone (not included) to pick up the desired
sound source. The speaker talks into the microphone, and the T31 transmitter broadcasts the
message over an FM radio signal. Listeners wear FM receivers to pickup the broadcast and
hear the speaker’s message.

Components:

PFM T31 Body pack transmitter

eliminate any unwanted noise as a result of
the transmitter being on.

Note: The microphone cord is also the
transmitting antenna. For maximum range,
make sure the microphone cord is hanging
as straight as possible.

5. Remember to turn the transmitter off
when you are done using it: Turn the “FM”
switch to the “Off” position.
