The Personal FM Listening System, model PFM 863, helps to overcome distance from the speaker,
reduces background noise and distractions for improved hearing in the classroom, job training, con-
sultation and more. The speaker uses the T863 transmitter equipped with a microphone to deliver
their message wirelessly to a listener. The listener uses the R863 receiver equipped with an ear-
phone or headphone to pick-up the speaker’s message. The Personal FM system helps to overcome
background noise, distance from the speaker, and enhances the quality of the message for all par-
ticipants. The Personal FM system operates on 863 MHz, meets RoHS approval guidelines, and is
backed by a 3 year factory warranty.
