Manual and
Quick Start-up Guide
Individuals with cardiac pacemakers and other similar medical devices
should consult with their physician before using any RF devices.
Though the output level of this wireless system is below 50 milliwatts,
the proximity of the transmitter to the implant device could pose a
threat.
As with any wireless product, environmental conditions can reduce or
in some cases prohibit a successful connection between the transmitter
and the receiver.
This device complies with Part 15 of the FCC Rules. Most users of
CAD Audio wireless products in the United States do not need a license
for operation. However, the rules for unlicensed operation state that
this device must not operate in excess of 50 milliwatts and it must not
cause harmful interference to other wireless devices, and must accept
interference received from other devices. Wireless products meeting
CAD factory standards adhere to these rules. The FCC reserves the right
to change these rules at any time. For more information contact the
FCC at 1-888-CALL-FCC (TTY: 1-888-TELL-FCC) or visit the FCC’s wireless
microphone website at:

TM WX1200
Introduction
Thank you for purchasing the CAD Audio TM WX1200 system.
We hope that you enjoy the easy and exciting performance that the
TM delivers for your next gig. CAD Audio/Astatic Commercial
has been creating high-value products since 1938 and prides itself on
supporting and developing the live performer. Our design criterion for
theWX1200 was straightforward: develop a high-performance wireless
microphone system agile enough to cope with today’s dynamic RF
environment that is both easy to use and exciting to operate.
The TM WX1200 includes the
following features:
• VHF Channelization for increased operating range
• Diversity Operation to minimize multipath
interference
•
• Scan-Link TM technology for instantaneous and
- First, the receiver conducts an environmental
frequency evaluation then selects a channel.
- Second, the receiver links to the transmitter
and sets the transmit frequency automatically.
• AA batteries for more than 10hrs of
continuous operation
• Transmitters have soft touch On & Mute switches
with multi-color LED indicators.
• Metal Chassis for a durable and formidable
shielded enclosure
•

Channelization
The CADWX1200 series wireless has 16 selectable VHF channels.
Channel indicators 0 through F are displayed on the receiver.
Corresponding frequencies (in MHz) are listed below.
0 175.125 8 178.125
1 175.375 9 178.925
2 175.775 A 180.725
3 175.975 B 181.525
4 176.175 C 182.025
5 176.525 D 183.225
6 176.925 E 184.525
7 177.925 F 185.125
7 of the channels can be used at any one time if optimal atmospheric
conditions exist.
CH 0 , CH 2, CH 4, CH 9, CH B, CH D and CH F are recommended for
simultaneous usage.

Operating Instructions
• Insert new high-quality alkaline AA batteries into your transmitter,
observing proper direction.
• Power up the receiver and transmitter.
• Scan-Link TM your system by pressing the Set/Scan button on the
receiver to automatically select operating channel.
•
IR node in alignment with the receiver IR node within a distance
of approximately 12". The receiver will automatically set the
is “Scan-Link’d.”
• To set up additional units continue the sequence while keeping
previously linked transmitters away from the receiver that is
attempting to Scan-Link TM .
