Transmitter On...
Turn on the transmitter by pressing and holding the
Power/Mute button (Fig. E/F) for a second or two, until the red
power indicator and the LCD window have come on.
Setting Transmitter Frequency
1. Press the Set button once and the small word "MENU"
will appear above the frequency. Press the Set button
again and the small flashing word "EDIT" will appear to
the right of "MENU". See Figures J-3 and J-4.
2. Use the Up/Down arrow buttons to change the transmitter
frequency. Press either arrow for single steps, or hold
down either arrow for rapid cycling through the range.
Frequencies "wrap around" when the top or bottom of the
band is reached. Select the exact frequency displayed on
the receiver.
3. To activate this frequency selection, press and hold the
Set button until the word "STORED" appears in the
transmitter's window. (If you do not wish to complete this
selection, just press the Set button once: the word
"ESCAPE" will appear briefly in the window and the
transmitter will return to the Menu mode.)
4. When finished entering a frequency, press the Up arrow
button once to move to "QUIT". Then press the Set
button once to exit the menu. The word "MENU" in the
transmitter window will go off, indicating the return to
normal operation.
When the transmitter is switched on and in normal operation,
the receiver's "RF" signal-level bars will display from bottom to
top, with more bars indicating increased signal reception. For
optimum performance at least four, and preferably five or more,
of the RF indicators should be displayed.
Setting Levels
Correct adjustment of transmitter audio input, receiver audio
output, and mixer/amplifier input and output levels is important
for optimum system performance.

System Operation
(Continued)
Set Transmitter Audio Input Level
ATW-T310 and ATW-T341 transmitters
A 4-position audio input gain setting, selected through the
function menu, serves to match the audio input level to the
transmitter for best modulation with minimum distortion.
Available choices are +12 dB, +6 dB, 0 dB and –6 dB. The
default value is +6 dB. Select the highest setting that does not
result in over-modulation with the highest audio/instrument input
levels (an AF indication on the receiver no higher than "0").
ATW-T371 transmitter
A 3-position audio input gain setting, selected through the
function menu, serves to match the audio input level to the
transmitter for best modulation with minimum distortion.
Available choices are +12 dB, +6 dB, and 0 dB. The default
value is +6 dB. In addition, a mechanical pad switch on the
condenser capsule (inside the screw-on wire mesh grille) can
provide another 6 dB of attenuation. For best performance,
adjust the input level using the function menu choices, keeping
the capsule's mechanical switch at 0 dB. If more audio
attenuation is needed than the menu provides, then set the
capsule's pad switch to –6 dB.
RF Power Adjustment
RF power may be set to "RF HI" (30 mW nominal) or "RF
LOW" (10 mW nominal) through the function menu. The default
setting is "RF LOW". While the High setting normally provides
maximum operating range, the Low setting will help extend
battery life. The Low setting may also be preferred in multi-
channel systems, or when operating very close to the receiver,
to reduce the possibility of interference or overload.
RF Interference
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 in
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 Audio-Technica professional
division. Extensive wireless information also is available on the
