Audio Technica ATW-1235 Installation And Operation Manual page 7

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- or three-character
code, such as "T2" or "11G," 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 back of the unit and the
frequency of each system appears on the outer carton. For
future reference, please record them in the space provided.
Because most of these authorized frequencies are shared
with TV broadcasting, frequency selection is largely dependent
upon which TV broadcast channels are in operation where
the wireless system is to be used.
Application
• Traveling frequencies:
(Normally work anywhere in the U.S.A. and Canada,
but as a result tend to be crowded.)
• For use only where there is no TV Channel 7:
• For use only where there is no TV Channel 8:
• For use only where there is no TV Channel 9:
• For use only where there is no TV Channel 10:
• For use only where there is no TV Channel 11:
• For use only where there is no TV Channel 12:
• For use only where there is no TV Channel 13:
Multi-channel Systems
Following are groupings of frequencies suggested for multi-channel wireless systems.
• For use where TV channels 7, 9, 11 and/or 13 are operating: 8D-8M-8S-10C-10J-10W-12L-12S-12V
Traveling frequencies T2, T3 and/or T8 may be used with any of the above frequencies except for: 8D,
8M and 10C. Interference may result from the use of these frequency combinations.
• For use where TV channels 8, 10 and/or 12 are operating: 7G-7I-9F-9Q-11G-11S-13Q or
Traveling frequencies T2, T3 and/or T8 may be used with any of the above frequencies with no
interference problems.
For future reference, please record your system information here (the serial numbers appear inside
the battery compartment of 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 opera-
tions 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.
