SYSTEM OVERVIEW
The HEARING HELPER
™
Tour Guide System is a portable, high-performance, wireless system
composed of the PFM 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 1-800-328-6190.
