STEP 1: Position the PPAT35 transmitter near the sound system or mixer from which it will receive audio.
STEP 2: Install the ANT 025 whip antenna. Gently thread the ANT 025 onto the stud recessed in
the hole on the top of the transmitter. The antenna length must NOT exceed 28 inches when fully extended.
It was found during test that the antenna length, when the length was greater than 28 inches, the device failed
the radiated emissions. It FAILED with the longer length.
STEP 3: Connect the power supply to the “Power In” connector (Figure 5) located in the back of the T35. Press in
the power button on the front of the T35. The “On Air” green LED indicator should illuminate. If not, go
back and check the power connections.
STEP 4: Select an application. The T35 has three pre-configured Application
Presets to choose from:
Hearing Assist, Music and Voice. The perform-
ance of the T35 is optimized for each selected application. Using the menu
control buttons on the front of the T35 (Figure 2), press the “ ” button
to access the “Application Presets” LCD screen.
Press the “+” and “-”
menu buttons to alternate between Hearing Assist, Music and
Voice
selection. When the desired Application Preset is displayed, press the
“Set” button to save the change into memory.
STEP 5:
The T35 is shipped from the factory in wideband mode with the fre-
quency set to 72.900 MHz. To change the frequency or bandwidth
on the T35, refer to the instructions on page 14.
STEP 6: Configure the T35 for the appropriate audio source. Using the menu con-
trol buttons on the front of the
T35 (Figure 2), press the “ ” button to
access the “Audio Source” LCD screen. Using the “+” and “-” menu
buttons (Figure 2), choose between MIC, SIMPLEX-MIC, or LINE.
When the desired audio input is displayed, press
the “Set” button to save
the change into memory. Lastly, connect the audio source to the audio
input jack in the rear of the T35 transmitter.
STEP 7: With the audio source playing, adjust the Audio Level control on the T35
so that the green “0 dB” LED generally lights and the red “+9 dB” LED
lights occasionally:
Press the
Audio Level “+” button
to incr
ease
the
audio level in .5dB steps. Press the
Audio Level “-” button to decrease
the audio level in .5dB steps. See Figure 3.
STEP 8: Listen with an FM receiver (see pages 20-21 for compatible Williams Sound receivers). Install the batteries,
plug in the earphone, turn on the receiver and walk around the listening area.
The signal should be clear and
quite loud when the volume is turned up.
IMPOR
TANT: The FM receiver being used with the T35 transmitter will need to be on the same frequency
and bandwidth as the transmitter. To retune the receiver, see page 23.
Please read through this manual carefully for detailed instructions and setup procedures.
