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.
If you have problems with the PFM system,don’t hesitate to call us toll-free at
1-800-843-3544.
SYSTEM OVERVIEW
Speaker Uses Transmitter
With Microphone
FM Radio Signal
Listeners use R31 or R32 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.
