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.
Tour Guide Uses the Body Pack
Transmitter With Microphone
FM Radio Signal
Listeners use Personal Receivers with
Headphones, Earphones, Or Neckloop
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.

THE PFM T32 OR T31 TRANSMITTER
The PFM Transmitter is a battery-powered body-pack model used with a microphone to pick up the
tour guide's voice. The transmitter produces an FM radio signal to broadcast the tour guide's voice to
the receiver units. A simple slide switch on top of the transmitter turns the unit on or off. The PPA
Transmitter operates on two AA non-rechargeable alkaline batteries (BAT 001), or two AA
rechargeable NiMH batteries (BAT 026).
MICROPHONES
A noise-cancelling, headband microphone (MIC 086) is the standard microphone. The noisecancelling microphone helps to reduce background sounds in noisy environments. The microphone
plugs into the “MIC” jack on top of the Transmitter. The microphone should be positioned directly
in front of the tour guide's mouth to achieve an optimal signal to noise ratio and so that head
movement does not affect the loudness of the signal. The microphone cord acts as the transmitting
antenna.
Optional Microphones
An optional Hearing Protector Headset Microphone (MIC 036) is also available for extremely high
noise environments. It features ear muffs that completely cover both ears and provides 24 dB noise
isolation for hearing protection.
An optional Lapel Clip Microphone can be used in quieter environments like museums or galleries.
The MIC 090 has an omnidirectional pick-up pattern. The MIC 056 has a directional (or cardioid)
pick-up pattern, which will reduce background noise somewhat.
A directional hand-held microphone (MIC 027) is also available for tour guides who prefer to hold
the microphone.
THE PPA R35 RECEIVER
The PPA R35 Receiver is a battery-powered body-pack receiver used with a headphone to hear the
signal produced by the transmitter. The receiver is pre-tuned to the transmitter and has a useradjustable volume on/off control, LED power and low battery indicator. The headphone plugs into
the “EAR” jack on top of the Receiver. The PPA R35 Receiver operates on two AA nonrechargeable alkaline batteries (BAT 001), or two AA rechargeable NiMH batteries (BAT 026).

OPTIONAL HEADPHONES AND EARPHONES
The optional HED 021 Lightweight Headphone is the standard headset for the Tour Guide System. It
offers excellent sound quality and wearing comfort. The foam earpads may be removed and washed in a
mild detergent, rinsed thoroughly, and air dried.
The headphone plugs into the “EAR” jack on top of the Receiver. The headphones are wired with a
mono plug. If a stereo headphone is substituted, it will only work on one side of the headphone.
The HED 008 is a heavy-duty, hearing-protector headset. The HED 008 earmuffs completely cover
the ears and provide 24 dB noise isolation for hearing protection in high noise environments.
The EAR 022 Surround Earphone offers excellent sound quality in a unique style that hangs on the
ear. It is easy to keep clean since the earphone does not enter the ear. It is not recommended for high
noise environments.
The EAR 013 and EAR 014 are single and dual Mini Earphones. The earbud-style features a foam
covering that fits in the outer ear. The foam pads can be removed for cleaning or replacement.
Replacement pads (EAR 015-10) are available.
The stylish HED 026 rear-wear headphone offers excellent sound quality; it rests comfortably over
the ears and wraps around the back of the head for a less obtrusive, relaxed fit.
For order information, contact Williams Sound at 1-800-843-3544.

1.
Install two (2) AA batteries. If you’re using rechargeable batteries, they must be charged before using.
2. Plug the microphone cord into the “Mic” jack on top of the transmitter.
3. Place the transmitter in the belt clip case provided.
4. Slide the Power Switch on top of the transmitter to “On.” The Power ON LED indicator should
illuminate Red.
5. The microphone should be placed as close to the speaker’s mouth as is practical. For lapel mics,
attach the microphone to a collar, lapel, or tie.
6.
When you are ready to speak, turn the Mic Mute Switch (speaker icon) to the “On” position. When you
are done speaking, mute the mic by turning the Mute Switch to the “Off” position (speaker icon with line
through it).
The transmitter can be placed in a pants pocket, or clipped onto a belt or waistband.
Note On The Transmitter Antenna:
The microphone cord is the transmitting antenna. Do not bunch up the cord or wrap it
around the transmitter. For maximum range, the cord should hang as straight as possible.

CHANGING THE PFM T32 FREQUENCY
FIG. 4: PFM T32 FREQUENCY CHANGE
By default, the T32’s frequency is to set 75.7 MHz (Channel G). If you experience FM interference, or
if you need to match a receiver’s frequency, it may be necessary to adjust the frequency on the T32.
Instructions:
1. Open the battery compartment using a coin in the slot in the bottom of the transmitter. Remove the
batteries.
2. Lift the battery compartment door up and pull to your left to expose the circuit board.
3. Refer to FIG 4 to locate the Channel Switch.
4. Use a small screwdriver to rotate the Channel Switch to correspond with the desired operating
frequency. Choose between 16 standard channels. Refer to the Channel Selection Chart in FIG 4 for
available channels.
5. Reinstall the batteries, then close the back of the transmitter.
6. Plug the microphone in and turn the transmitter on to provide a tuning signal for the receivers.
Important: Make sure all receivers being used match the frequency of the transmitter. Refer to the
receiver’s instruction manual for frequency change instructions.
