Audio Technica ATW-201 Installation And Operation Manual page 6

Frequency Selection
Each transmitter/receiver system operates on a single factory-
aligned, crystal-controlled frequency. Available frequencies are
shown in the chart below.
Operating frequency is specified by a two character code,
such as "T2," in addition to the actual frequency in MHz. The
frequency of each transmitter appears on a label on the outside
of the unit. The frequency of each receiver appears on a label
on the rear panel of the unit and the frequency of each system
appears on the outer carton. For future reference, please record
them in the space provided below.
• Traveling frequencies:
Systems on these frequencies may be combined for up to three simultaneous
operating channels.
For future reference, please record your system information here (the serial numbers
appear near the screwdriver clip in each transmitter, and on the bottom of
each receiver):

RF Interference
If you encounter receiving interference (from other than an
operating TV station), often it can be eliminated by adjusting the
receiver's squelch control, as described on page 5.
Please note that wireless frequencies are shared with other
radio services. According to Federal Communications
Commission regulations, "Wireless microphone operations are
unprotected from interference from other licensed operations
within the band. If any interference is received by any
Government or non-Government operation, the wireless
microphone must cease operation..."
If you need assistance with operation or frequency selection,
please contact your dealer or the A-T professional division.
Extensive wireless information also is available on the A-T Web
site at www.audio-technica.com.
