System Overview
The Personal PA®Tour Guide System is a portable, high-performance, wireless listening system. It is composed of a PPA T36
Transmitter, microphone, and optional PPA R37 or R35-8 receivers equipped with headphones or earphones. 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 Personal PA®Tour Guide System can be used for large or small tour groups, and in noisy or quiet environments.
Your Personal PA®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 difculties, 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 Personal PA®Tour Guide System, don’t hesitate to call Williams Sound at 1-800-843-3544 or +1
952 943 2252.

MAN 158C
Tips for Using the System
The nominal operating distance between the transmitter and receiver is about 46 meters (150 feet). The operating range will vary
in different buildings and surroundings. In some locations, the signal may momentarily disappear. This is called a “drop-out” and is
due to reection and cancellation of the radio signal. Moving a few feet should restore the signal.
Keep the transmitter and receiver units at least 1 meter (3 feet) apart. If the transmitter gets too close to a receiver, it may 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 60 meters (200 feet). 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 more than 60 meters (200 feet) between groups. The physical separation of groups
takes advantage of the FM capture effect which causes receivers to lock onto the closest transmitter.

60 METERS
Figure 12: Tour Guide Group Separation
In Case Of Difculty
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” terminals are installed correctly.
3. If the rechargeable batteries 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 fully charge the receiver and transmitter (refer to charger instruction manual). This should
restore normal battery life. Rechargeable batteries will gradually lose their capacity over time and may need to be replaced
every 1-2 years.
4. Make sure the microphone is plugged into the T36 Transmitter and the earphone or headphone is plugged into the PPA R37
or R35-8 Receiver.
5. Move the transmitter and receiver closer together. You may be out of range. When using the system 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
transmitters at least 60 meters (200 feet) 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 channel (see pages 8-9). Call your Williams Sound
representative at 1-800-843-3544 or [phone] for details.
