Setting Receiver Frequency Manually
1. Press the Mode/Set button once; then only the frequency will appear in the LCD
window. (The receiver is now in the Menu mode.) See Figure D-2.
2. Press the Mode/Set button again; the Alert light will come on and the frequency in
the window will flash. (The receiver is now in the Edit mode, Fig. D-3.)
3. Use the Up/Down arrow buttons to change the frequency. Press either arrow for
single steps, or hold down either arrow for rapid cycling through the band.
Frequencies "wrap around" to the other end of the range when the top or bottom
of the band is reached. Choose a frequency appropriate for your area, avoiding
frequencies with active TV channels. (See the frequency listings from page 14)
4. To activate this frequency selection, press and hold the Mode/Set button until the
word "STORED" appears in the receiver's window. (If you do not wish to
complete this particular selection, just press the Mode/Set button once. The word
"ESCAPE" will appear briefly in the window and the receiver will return to the
Menu mode.)
5. When finished entering a frequency, press the Down arrow button once to move
to "QUIT". Then press the Mode/Set button once to exit the menu. The "RF" and
"AF" scales will reappear in the window, indicating the return to normal
operation.
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.
Set Transmitter Audio Input Level
ATW-T310 and ATW T341 transmitter
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 setting 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" );
watch the receiver's "AF" bar-graph "+3/+6" indications and the Alert light, to make
certain that they are not triggered by the highest audio levels.
The transmitter's normally-on red LED power indicator will blink off if the peak audio
input exceeds the maximum desirable level.
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
disortion.
Available choices are +12 dB, +6dB and 0dB. 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 6dB of attenuation. For best performance, adjust the input
level using the function menu choices, keeping the capsule´s mechanical switch at
0dB. If more audio attenuation is needed, set the capsule´s pad switch to -6 dB.
RF Power Adjustment
ATW-T310 Unipak RF Power Adjustment 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 the National 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. Extensive wireless information also is available on the Audio-Technica web site
at www.audio-technica.com.
