Audio Technica ATW-3110A Installation And Operation Manual page 17

Incorrect settings on the receiver and/or transmitter can make the wireless system's operation seem poor, or even "dead."
To eliminate the possibility that incorrect function settings are the source of problems, restore both the receiver and the
transmitter to their factory-default settings.
RECEIVER – To return all receiver functions to their original factory-default settings:
1. First, turn the receiver off.
2. Hold in the Mode/Set button while pressing the Power switch to turn the receiver back on. The LCD will briefly show
"RESET", followed by "WAIT" (release the Mode/Set button), before commencing normal-mode operation with all
factory-default settings restored.
(3.) (If the default frequency is not useable in your area, set both the receiver and the transmitter to the same suitable
frequency.)
TRANSMITTER – To return all transmitter functions to their factory-default settings:
1. Press the Set button once to move to Menu mode.
2. Press the Up arrow twice to move to "PRESET" in the LCD window.
3. Press the Set button once and "LOAD" will appear in the LCD.
4. Press and hold the Set button until "DEF" appears in the LCD.
5. Press and hold the Set button until "LOADED" appears briefly in the LCD. The window will then revert to "PRESET".
6. Press the Down arrow once to move to "QUIT".
7. Press the Set button once to exit the Menu mode and return to normal operation, with all factory-default settings restored.
(8.) (If the default frequency is not useable in your area, set both the receiver and the transmitter to the same suitable
frequency.)
The red Alert indicator on the receiver signals the user regarding a number of operating conditions.
Transmitter conditions:
No RF When no RF signal is received from transmitter.

 Weak RF When only one or two "RF" signal-strength bars are on.
 Transmitter Muted When the transmitter is in the Mute* mode.
Transmitter Audio Too High When audio modulation level from the transmitter is close to the clipping point

(AF +3/+6 bars).
 Batteries Weak When only one bar of the Battery* "fuel gauge" is on.
Receiver conditions:
 Edit Mode When the receiver is in the Function Edit mode.
* These functions use digital data supplied from the transmitter. It can take up to several seconds for the receiver display to be
"updated" with the latest mute/unmute and battery status information. This is normal operation for both the Alert light and the
"BATT" indication.
