INSTALLATION GUIDE & USER MANUAL

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.

RECYCLING INSTRUCTIONS

1. Install two (2) AA batteries. If you’re using rechargeable batteries, they must be charged before

using. See battery information on page 13.

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 illu-

minate 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.

The PFM System comes with an omnidirectional, lapel-clip style microphone. It should be

clipped to a collar, lapel, tie, or neckline as close to the mouth as possible and centered

on the body as shown.

FIGURE 4: CORRECT MICROPHONE PLACEMENT

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.

USING THE PFM T32 TRANSMITTER

FIGURE 3: T32 TOP VIEW

CHANGING THE PFM T32 FREQUENCY

FIG. 5: PFM T32 FREQUENCY CHANGE

By default, the T32’s frequency is to set 72.9 MHz (Channel E). 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 5 to locate the Channel Switch.

4.Use a small screwdriver to rotate the Channel Switch to correspond with the desired operating fre-

quency. Choose between 16 standard channels. Refer to the Channel Selection Chart in FIG 5 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.

Gain Control Adjustment

If necessary, the microphone gain control on the T32

can be increased or decreased to meet the demands of

specific listening applications.

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 6 to locate the microphone gain con-

trol.

4. Using a small screwdriver, turn the gain control

fully counterclockwise to reduce the gain. Turn the

gain control fully clockwise to increase the gain

5. Close the back of the case and battery door.

COMPRESSION ADJUSTMENT

By default, the T32 transmitter compression jumper is set to “Off” for normal operation, or 1:1 compression.

For hearing assistance applications, the compression jumper can be set to “On” for 2:1 compression.

Instructions:

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 6 to locate the Compression Selector.

4. Gently remove the jumper from the circuit board by pulling it up and away from the unit. You will see

three exposed “pins.”

To turn compression “On” (2:1 Compression): Press jumper on to the top twopin locations as shown

on left.

To turn compression “Off” (1:1 Compression): Press jumper on to the bottom twopin locations as

shown on left.

5. Close the back of the case and battery door.
