Installation and Operation
CAUTION! The circuits inside the receiver and transmitter have
been precisely adjusted for optimum performance and
compliance with federal regulations. Do not attempt to open the
receiver or transmitter. To do so will void the warranty, and may
cause improper operation.
This device complies with part 15 of the FCC Rules. Operation is
subject to the condition that this device does not cause harmful
interference.
This device complies with INDUSTRY CANADA R.S.S. 210, en
conformité avec IC: RSS-210/CNR210. Operation is subject to
the following conditions: 1) This device may not cause harmful
interference and 2) this device must accept any interference

operation.
Introduction
Thank you for choosing an Audio-Technica professional
wireless system. You have joined thousands of other satisfied
customers who have chosen our products because of their
quality, performance and reliability. This Audio-Technica
wireless system is the successful result of years of design
and manufacturing experience.
The U100 systems are designed primarily for use in audio-for-
video applications, with the receiver mounted on a camera and
connected to the camera’s audio input. U100 systems provide
a choice of 100 PLL-synthesized UHF frequencies. Each
system includes a receiver and either a body-pack or plug-on
transmitter:
System Receiver Transmitter
ATW-U101 ATW-R100 ATW-T101 Body-pack
ATW-U102 ATW-R100 ATW-T102 Plug-on
The ATW-R100 receiver features true diversity reception. Two
antennas feed two completely independent RF sections on
the same frequency; automatic logic circuitry continuously
compares and selects the superior received signal, providing
better sound quality and reducing the possibility of dropouts.
Front-end helical filter design improves rejection of
interference. The receiver also offers balanced audio output
with level control, a headphone jack with volume control,
removable antennas, a hinged battery door, and LED
indicators. It operates on two internal 9V batteries or external
12V DC.
Each transmitter is powered by one internal 9V battery and
has an Off/Standby/On switch, input level control, battery
condition indicator and channel selector switches. The
ATW-T101 body-pack transmitter has an industry-standard
TB5M input connector with both low- and high-impedance
inputs plus a bias connection. The ATW-T102 has a 3-pin
XLRF-type input connector with a locking collar.
Please note that in multiple system applications there must
be a transmitter-receiver combination set to a
separate
frequency for each input desired (only one transmitter for each
receiver). Because the operating frequencies of U100 Systems
are in UHF TV frequencies, only certain wireless frequencies
may be useable in a particular geographic area. Also, only
certain of the available operating frequencies may be used
together. Suggestions for multiple-system frequency grouping
will be found on page 7.
Warning: To prevent fire or shock hazard, do
not expose this appliance to rain or moisture.
Attention: Pour prévenir feu ou choc
électrique, ne pas exposé l’appareil à la pluie
ou à l’humidité.
Notice to individuals with implanted cardiac pacemakers or
AICD devices:
Any source of RF (radio frequency) energy may interfere with
normal functioning of the implanted device. All wireless
microphones have low-power transmitters (less than 0.05 watts
output) which are unlikely to cause difficulty, especially if they
are at least a few inches away. However, since a “body-pack”
mic transmitter typically is placed against the body, we suggest
attaching it at the belt, rather than in a shirt pocket where it may be
immediately adjacent to the medical device. Note also that any
medical-device disruption will cease when the RF transmitting
source is turned off . Please contact your physician or medical-
device provider if you have any questions, or experience any
problems with the use of this or any other RF equipment.
