Thank you for purchasing the Hearing Helper ™ Personal FM System from Williams Sound Corp.
Anyone needing auditory assistance to overcome background noise, reverberation, or distance
from the sound source can benefit from the Personal FM System.
Your PFM System has two principal parts: the Transmitter and the Receiver. Much like a
miniature radio station, the Transmitter and microphone pick up the sounds you want to hear and
broadcast them over an FM radio signal. The receiver and earphone are used to pick up the
broadcast up to 100 feet away.
To avoid difficulties, please read through these instructions as you begin to use the system. Then
save them for questions that arise as you continue to use your Williams Sound Personal FM
System.
Speaker Uses Transmitter
With Microphone
FM Radio Signal
Listeners use Receivers with Earphones,
Headphones, Or Neckloop
The speaker wears the body-pack transmitter and a clip-on microphone. The speaker’s voice is
broadcast as an FM radio signal over a distance of 100-150 feet (30-45 m). Listeners use the
pocket receiver and earphone or headphone to hear the speaker’s voice directly, with reduced
background noise. A neckloop telecoil coupler allows the system to be used with telecoil
(T-Switch) equipped hearing aids.
