AWM6031DU system has been engineered to be dependable UHF system with a wide audio
frequency range, high S/N ratio, and outstanding performance equal to that of any
professional wireless systems costing much more. This is achieved through strict
component selection and high quality circuit design. A delicately designed silence
circuit eliminates static noise when the transmitters are either turned off or out of
transmission range. An auto mute circuit is incorporated in these systems to
effectively eliminate the popping noise when the switch is turned on or off.

-
-
-
-
Place one 9V battery into the battery
housing of the AWX6030M transmitter with the battery polarity oriented
as indicated. Connect the supplied lapel (lavaliere) microphone to the
AWX6030M transmitter.
-
Turn on the power of the AWR6031DU
receiver. The Power On LED light will be turned on.
-
On the AWX6030M, the On/Off switch has
three positions: “ON”, “STDBY” and “OFF”. When the On/Off switch is
turned to the “STDBY” or directly to the “ON” position, the low battery
LED indicator will blink once and then stay off. If the low battery LED
indicator stays on, the 9V battery needs to be replaced. When the On/Off
switch is set to the “STDBY” or “ON” position, the Antenna A or Antenna
B LED light on the AWR6031DU receiver will be turned on. The AF LED
light will be on whenever the lavaliere microphone connected to the
AWX6030M transmitter receives any sound while the On/Off switch is set
to the “ON” position. The audio level adjustment knob is preset at
midpoint. If you need to increase the audio level, use a screwdriver to
turn the audio level adjustment knob clockwise. Turn the audio level
adjustment knob counter-clockwise to reduce the audio level.
-
Adjust the volume control knob on the
AWR6031DU receiver to have an optimal sound quality.
-
-
-
-
Place one 9V battery into the battery
housing of the AWX6030H transmitter with the battery polarity oriented
as indicated. Connect the supplied headset microphone to the AWX6030H
transmitter.
-
Turn on the power of the AWR6031DU
receiver. The Power On LED light will be turned on.
-
On the AWX6030H, the On/Off switch has
three positions: “ON”, “STDBY” and “OFF”. When the On/Off switch is
turned to the “STDBY” or directly to the “ON” position, the low battery
LED indicator will blink once and then stay off. If the low battery LED
indicator stays on, the 9V battery needs to be replaced. When the On/Off
switch is set to the “STDBY” or “ON” position, the Antenna A or Antenna
B LED light on the AWR6031DU receiver will be turned on. The AF LED
light will be on whenever the headset microphone connected to the
AWX6030H transmitter receives any sound while the On/Off switch is set
to the “ON” position. The audio level adjustment knob is preset at
midpoint. If you need to increase the audio level, use a screwdriver to
turn the audio level adjustment knob clockwise. Turn the audio level
adjustment knob counter-clockwise to reduce the audio level.
-
Adjust the volume control knob on the
AWR6031DU receiver to have an optimal sound quality.
-
-
-
-
Place one 9V battery into the battery
housing of the AWX6030G transmitter with the battery polarity oriented
as indicated. Connect the supplied guitar to the AWX6030G transmitter.
-
Turn on the power of the AWR6031DU
receiver. The Power On LED light will be turned on.
-
On the AWX6030G, the On/Off switch has
three positions: “ON”, “STDBY” and “OFF”. When the On/Off switch is
turned to the “STDBY” or directly to the “ON” position, the low battery
LED indicator will blink once and then stay off. If the low battery LED
indicator stays on, the 9V battery needs to be replaced. When the On/Off
switch is set to the “STDBY” or “ON” position, the Antenna A or Antenna
B LED light on the AWR6031DU receiver will be turned on. The AF LED
light will be on whenever the guitar or any electrical instrument
connected to the AWX6030G transmitter generates sound while the On/Off
switch is set to the “ON” position. The audio level adjustment knob is
preset at midpoint. If you need to increase the sound level, use a
screwdriver to turn the audio level adjustment knob clockwise. Turn the
audio level adjustment knob counter-clockwise to reduce the sound level.
-
Adjust the volume control knob on the
AWR6031DU receiver to have an optimal sound quality.
OPERATION NOTES
- The AWX6030,
AWX6030M, AWX6030H, or AWX6030G needs to be turned off before changing
the 9V battery.
- Signal dropout or
unexpected noise may be caused by a low battery or by an excessive
distance between the transmitter and the receiver. If you encounter
signal dropout or unexpected noise, please check the battery first. If
battery is still fresh, try to readjust the antennas on the AWR6031DU
receiver.
- Avoid placing the
receiver in a corner to prevent any RF reception deterioration.
- Avoid placing the
receiver antennas close to an obstruction or close to any metal surface.
- Try to place the
receiver as far away from any digital equipment, including computers and
some CD players, as possible.
- If more than one
AWM6031DU wireless microphone systems are stacked together or placed in
a rack, do not let the antennas touch each other or cross each other.
- Before the
AWM6031DU is to be used in a new location, place the AWR6031DU receiver
at the intended location and walk-through the area with the transmitter
to locate any radio frequency blind spot, where a momentary loss of
sound or short period of noise may occur whenever the transmitter is
moved to this spot.
- Do not drop the
transmitter on the floor or strike the transmitter with any object.
- Always turn off
the transmitter and remove the battery if the transmitter is not to be
used for a period of time to prevent the transmitter from being damaged
by a leaking battery.
