Tour Guide Uses the Body Pack
Transmitter With Microphone
FM Radio Signal
Listeners use Personal Receivers with 
Earphones, Headphones, 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.
SYSTEM OVERVIEW
The FM Tour Guide System is a portable, high-performance, wireless system composed of the
PFM T31 Transmitter and TGS R30 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 FM System can be used for large or small tour groups and in noisy or quiet environments.
Your FM 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 FM Tour Guide System, don’t hesitate to call Williams Sound at
1-800-843-3544.

THE PFM T31 TRANSMITTER
The PFM T31 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 PFM T31 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 noise-can-
celling 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 move-
ment does not affect the loudness of the signal. The microphone cord acts as the transmitting anten-
na.
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.
A small hand-held microphone (MIC 026) is also available for tour guides who prefer to hold the
microphone.
THE TGS R30 RECEIVER
The TGS R30 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 user-
adjustable volume control. The headphone plugs into the “EAR” jack on top of the Receiver.
The receiver is turned on by rotating the volume control wheel. The TGS R30 Receiver operates
on two AA non-rechargeable alkaline batteries (BAT 001), or two AA rechargeable NiMH
batteries (BAT 026).

HEADPHONES AND EARPHONES
The 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. Replacement pads (HED 013) are available.
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.
OPTIONAL HEADPHONES AND EARPHONES
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.

TGS R30 FREQUENCY CHANGE INSTRUCTIONS
Selecting a frequency for the R30, R31, R32 and R7-4 receivers requires an adjustment to the
internal tuning coil(s). See figure below for receiver types to locate the coils to be adjusted. A
plastic tuning wrench (PLT 005) will be needed to adjust these receiver tuning coils.
Most Williams Sound single channel Receivers are set at the factory to 72.9 MHz. The standard
four-channel receivers (R7-4), channels 1-4, are usually set to frequencies 72.1, 72.5, 72.9, 75.7
MHz respectively.
The Receiver must be tuned with a weak and somewhat noisy signal. If tuned too close to the
transmitter, with a strong signal, the most accurate tuning of the receiver is not possible.
TOCHANGE THE FREQUENCY TO ANOTHER CHANNEL:
Step 1: Set the transmitter to the channel desired and remove the antenna.
Step 2: Connect an audio source to the transmitter such as a CD or cassette player or
microphone or have someone talk into the transmitter’s microphone.
Step 3: Move the receiver about 25 feet away from the transmitter to set the tuning.

FIGURE 4: TOUR GUIDE GROUP SEPARATION
HINTS FOR USING THE SYSTEM
Normal operating distance between the transmitter and receiver is about 30 meters. The operating
range will vary in different buildings and surroundings. In some locations, the signal may momentar-
ily disappear. This is called a “drop-out” and is due to reflection and cancellation of the radio signal.
Moving a few feet will restore the signal.
Keep the transmitter and receiver units at least a meter apart. If the transmitter gets too close to a
receiver, it can overload the receiver, causing noisy reception or blocking of the signal.
Do not use more than one transmitter on the same channel (frequency) at the same time unless they
are physically separated by more than 30 meters. Operating more than one transmitter on the same
channel at the same time in the same place will result in interference.
USING MULTIPLE SYSTEMS FOR MULTIPLE GROUPS:
For multiple tour groups within the same facility, multiple Tour Guide Systems may be operated on
the same channel at the same time by maintaining physical separation of 30 meters between groups.
The physical separation of groups takes advantage of the FM capture effect which causes receivers to
lock onto the closest transmitter.

NON-RECHARGEABLE BATTERIES
In normal use,two AA 1.5 V alkaline batteries (BAT 001) will last about 8 hours in the PFM T31
Transmitter and approximately 20 hours in the TGS R30 Receiver. If the sound becomes weak or
distorted, replace the batteries. Do not leave dead batteries in the receivers. Battery corrosion is not
covered by the Williams Sound five year warranty.
RECHARGEABLE BATTERIES
The PFM T31 Transmitter and TGS R30 Receivers can use rechargeable AA batteries
(BAT 026). On an overnight charge, these NiMH batteries are designed to operate a PFM T31
Transmitter for approximately 6 hours, and TGS R30 Receivers for 14 hours.
The battery installed in the receiver may be recharged in the receiver only if it is a NiMH battery,
and only if a Williams Sound CHG 1600 Multi-Charger is used. Damage from improper charging is
not covered by the Williams Sound five year warranty.
IMPORTANT RECHARGEABLE BATTERYINFORMATION
Rechargeable batteries are shipped in a discharged condition. They must be charged for a complete
charge cycle before the first use (approximately 15 hours). Rechargeable batteries will need to be
replaced after 1-2 years of use. Do not dispose of batteries in fire. Do not open batteries - toxic
chemicals inside.
!! IMPORTANT WARNINGS !!
DO NOT ATTEMPT TO RECHARGE ZINC CARBON (“HEAVY DUTY”), ALKALINE, OR LITHIUM BATTERIES!
DO NOT ATTEMPT TO RECHARGE DISPOSABLE BATTERIES! These batteries may heat up and
explode, causing possible injury and damage to the equipment.

switches the charger to a higher-rate, overnight charge mode on a 15 hour timer. After 15 hours, the
“Complete / Maintain” light will come on and the CHG 1600 reverts to trickle mode. Any time the
button is pressed, the 15 hour timed charge begins again. The CHG 1600 Charger does not monitor
individual unit battery state.
Charging Instructions
Step 1: Plug the power supply into an AC wall outlet. Plug the power connector into the jack on
the right side of the CHG 1600’s control panel.
Step 2: Make sure the units being charged are turned OFF. DO NOT attempt to charge non-
rechargeable batteries.
Step 3: Place the units in the slots so that the charging pins and the unit’s side contacts are cou
pled. The “CHG” indicator next to the unit will be dimly lit.
Step 4: When all units are in place, press the red button on the CHG 1600’s control panel. The
red “Overnight Charge” indicator on the CHG 1600’s control panel will light during
charging, and the “CHG” indicators next to each unit will be brightly lit.
Step 5: The CHG 1600 will charge the units for approximately 15 hours, then automatically
resume a trickle charge. The “Complete/Maintain” indicator will come on.
Units may be fully charged before the green “Complete/Maintain” indicator is lit. Units
may remain in the CHG 1600 Multiple Charger for more than 15 hours without harm.

INCASE OFDIFFICULTY
If your Tour Guide System is not working, check the following:
1. Read through the manual and user guide carefully to verify proper setup and installation
of your system.
2. Make sure the batteries are fresh or completely charged and that the “plus” and “minus” termi-
nals are installed correctly.
3. If the rechargeable batteries will only work for a short period of time (less than 1 hour) even
after they are fully charged, they must be regenerated. Leave them in the receiver or transmitter
with the unit turned on, for 5 - 6 hours. Then turn receiver or transmitter off, place it in the
charger, and charge for 14 - 16 hours. This should restore normal battery life. Rechargeable bat-
teries will gradually lose their capacity over time and should be replaced every year.
4. Make sure the microphone is plugged into the PFM T31 Transmitter and the headphone is
plugged into the TGS R30 Receiver.
5. Move the transmitter and receiver closer together. You may be out of range. When using the sys-
tem indoors, it’s normal for the signal to momentarily disappear in certain locations. This is
called a “drop-out.” Moving a few feet will restore the signal.
6. Do not try to use more than one transmitter on the same channel in close proximity to each
other. MORE THAN ONE TRANSMITTER ON THE SAME CHANNEL WILL RESULT IN
INTERFERENCE IF THEY ARE CLOSE TOGETHER. Keep the systems at least 30 meters
apart or use separate channels for each system used.
7. If you are still hearing interference on the receivers, turn the transmitter off and listen with a
receiver. If you hear the interference with the transmitter off, you need to change to a clear chan-
nel. Call your Williams Sound at 1-800-843-3544 for details.
