SYSTEM OVERVIEW
The HEARING HELPER™Tour Guide System is a portable, high-performance, wireless system
composed of the PFM T32 or T31 Transmitter and PPA R35 Receivers and designed for use in
guided tour applications. The system allows one-way transmission of a tour guide’s voice to group
members using an FM radio signal. Using the system helps group members overcome background
noise and distance from the person speaking.
The HEARING HELPER™System can be used for large or small tour groups and in noisy or quiet
environments.
Your HEARING HELPER™Tour Guide 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 receivers and headphones are used to
pick up the broadcast up to 100 meters 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 system.
If you have problems with the HEARING HELPER™Tour Guide System, don’t hesitate to call
Williams Sound at 1-800-843-3544.

The tour guide wears the body-pack transmitter and headset microphone. The guide’s
voice is broadcast as an FM radio signal over a distance of up to 100 meters. Listeners use
the pocket receiver and 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, at somewhat reduced range.
