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.

Safety Information
HEARING SAFETY:
CAUTION!
The tour guide system is designed to amplify sounds to a high volume level which could potentially cause hearing damage if used
improperly.
To protect your hearing and the hearing of others:
1. Make sure the volume on the receiver is turned down before putting on the earphone or headphone. Then adjust the volume to
a comfortable level.
2. Set the volume level on the receiver at the minimum setting that you need to hear.
3. If you experience feedback with the receiver (a squealing or howling sound), reduce the volume setting and move away from
the T36 transmitter’s microphone.
4. Do not allow children or other unauthorized persons access to the receiver.
BATTERY SAFETY AND DISPOSAL:
CAUTION!
The transmitter and receiver may be supplied with alkaline batteries. Do not attempt to recharge alkaline batteries, which may
explode, release dangerous chemicals, cause burns, or other serious harm to the user or product.

3. Optionally, plug in a desired audio source such as a CD or MP3 player using the “Auxiliary Input” jack (WCA 087 stereo auxiliary
input cable included). If mic and auxiliary sources are used together, the audio will be mixed. If only auxiliary source is desired,
the mic can be muted. Do not remove the mic from the “Mic Jack” as the cable is also the transmitting antenna!
4. Turn the unit on: press and hold the “ON/OFF/MUTE” button for three seconds. The “Power On” indicator should illuminate
green.
5. Select the desired operating frequency. Use the “Channel Selector” knob to select any of the 16 available channels on 72-76
MHz. Refer to the channel selection chart, Figure 3.
Make sure the receiver being used is operating on the same frequency as the T36 transmitter!
NOTE: Up to eight T36’s can operate simultaneously on channels 1-8 (Figure
3) when used with an R35-8 receiver.
6. Position the headset microphone boom as close to the speaker’s mouth
as possible without actually touching. Lapel clip microphones should be
attached to a collar or lapel, as close to the speaker’s mouth as possible.
The transmitter can be placed in a pocket, or clipped onto a belt or
waistband.
7. When you pause from speaking, you may mute the microphone by pressing
the“ON/OFF/MUTE” button once momentarily. The “ON/OFF/MUTE” button
will ash red. To unmute the mic, press the “ON/OFF/MUTE” button once
momentarily again.
IMPORTANT: When the T36 transmitter is not being used, remember
to turn the unit OFF by pressing and holding the “ON/OFF/MUTE”
button for three seconds. The “Power On” indicator should not be lit.
