S ystem O verview
The Personal PA™ Tour Guide System is a portable, high-performance, wireless listening system. Much like a miniature
radio station, the transmitter broadcasts over an FM radio signal. The receivers are used to pick up the broadcast up to 150
feet away. The system helps large or small groups overcome background noise and distance to clearly hear the tour guide.
The system is composed of a PPA T46 Transmitter, microphone, and optional PPA R37 or R35-8 Receivers equipped
with headphones, earphones, or neckloops.
To avoid difficulties, please read through these instructions, and keep them for reference.
If you have problems, don’t hesitate to call Williams Sound customer service at 1-800-843-3544.
FCC Regulation
FCC regulations, section 15.21, requires the user to comply with the rules of transmitter operation. Any changes or
modifications not expressly approved for compliance may result in the loss of all privileges and authority to
operate this equipment.

Using the T46 Transmitter
Getting Started
1. Make sure there are two alkaline or rechargeable NiMH AA batteries in the transmitter. If batteries are not
installed, see Battery Information on page 7.
2. Plug the microphone cord into the “Mic Jack” on top of the transmitter (see Figure 2). In order for the

should illuminate green. The display on the front face of the unit will turn on, displaying the Williams Sound
logo for 3 seconds while the transmitter is booting up. The display will then switch to the Main Screen (see
Figure 3). Note that the factory default settings at initial power up are unmuted microphone audio and an
unlocked menu. The “Mute Indicator” and “Menu Locked Indicator” are shown for reference in Figure 3, but
will not be lit on initial power up.
Muting the Microphone
Press the “On/Off/Mute” button once momentarily to mute the microphone. The “On/Off/Mute” button will flash red, and
the display on the front of the unit will show display a brief message indicating the microphone has been muted, then
return to the Main Screen. The “Mute Indicator” will now be lit.

PPA T46 Manual Page 5 Preliminary
To unmute the microphone, press the “On/Off/Mute” button once momentarily. The “On/Off/Mute” button will stop

Using the Auxiliary Jack
The “Auxiliary Input” jack (see Figure 1) on the top of the T46 can be used to transmit background music or a voice
recording from a CD or MP3 player.
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 microphone and auxiliary sources are used together, the audio will be mixed. If only auxiliary source is desired, the
microphone can be muted. Do not remove the microphone from the “Mic Jack”, as the cable is also the transmitting
antenna!
Locking the Menu
Press and hold both the left and right buttons for 3 seconds to lock the menu. A message indicating that the menu has
been locked will appear briefly on the display, which will then return to the Main Screen. The “Menu Locked Indicator”
will appear on this screen (see Figure 1 on Page 4).

PPA T46 Manual Page 7 Preliminary
To unlock the menu, simply press and hold the left and right buttons for 3 seconds again. The display will briefly show a
message indicating that the menu has been unlocked, and then return to the Main Screen. The “Menu Locked Indicator”
on the Main Screen will be off.
The PPA T46 Transmitter remembers the Menu Lock setting, and on power up will default to its most recent setup.
Restoring Factory Defaults
Press the “Menu” button to step through the Basic Features to the “Enter Advanced Setup” screen. Press the right button
to select “Yes”. Press the “Menu” button to step through the Advanced Features. At the end of the Advanced Features
menu is a screen that provides the option of rebooting the T46 with factory default settings. Press the right button to

•Screen Time-Out Period = 20 seconds
•Screen Brightness Adjustment = High
•Menu Lock = Off
•Mute = Off
Using the A T46 in Dual reset Mode
The PPA T46 transmitter has the ability to be set up in 2 modes at once, so that a user can toggle back and forth between
them. Each mode has “Dual Presets” for each of the 3 basic features: frequency, master volume, and auxiliary volume.
This means that with the touch of a button, you could:
•Mute your auxiliary input source, or drop its audio to a low background level you can comfortably speak over.
•Switch your Master Volume level as you hand the transmitter off to a coworker with a softer voice.
•Switch between two transmission frequencies.
Or any combination of these features.
Turning Dual reset Mode On or Off:
1. Power the unit down by holding the “On/Off/Mute” button for 3 seconds.
2. Press and hold the “Menu” button on the front face of the unit.
3. While holding the “Menu” button, press and hold the “On/Off/Mute” button for 3 seconds to turn the unit back
on.
If the unit was in Normal Mode, this will bring it up in Dual Preset Mode. If the unit was in Dual Preset Mode, this will
bring it up in Normal Mode. As with all settings, the PPA T46 will remember this setting, and revert to it at power on.

PPA T46 Manual Page 8 Preliminary
Setting Up the Dual resets
When the PPA T46 is in Dual Preset mode, it has 2 Basic Features menus – one for
each preset (P1 and P2). When adjusting features, the menu entered is determined by
which preset is selected when the “Menu” button is pressed. A “Preset Indicator” in
the top left corner (see Figure 5) of each Basic Features screen shows which settings
are being adjusted. Features are adjusted the same way they are in Normal Mode.
The Advanced Features apply to both presets.
Switching Between Dual resets
From the main screen, use the left and right buttons to toggle between the Dual Presets.
