III. Operating Instruction:
1. Setting up:
(1) Connect the supplied DC adapter to the power receptacle on Receiver, and then

plug the DC adapter to a wall outlet.
(2) Press the Receiver’s power switch to turn the power on, and the status LED will
light up green.
(3) Press the microphone’s power switch to turn the power on, and the status LED
will light up green. When the microphone connecting LED on the Receiver lights
up red, it indicates the microphone signal is een received y the Receiver.
(4) If the feed ack noise appears when the volume is too high or the microphone is
too close to the speaker, turn the volume down.
(5) For est result, keep the microphone to the sound source in etween 2 to 5 cm.
2. Turning off
(1) Keep pressing the microphone power switch for 2 to 3 seconds till the status LED
goes off. When the microphone is een turned off, the microphone connecting
LED on the Receiver will also go off.
(2) Press the power switch on the Receiver till the status LED goes off.
3. Replacing atteries
(1) When the status LED keeps linking after the microphone is on, it indicates the
attery energy is running low, so please replace the atteries.
(2) As shown in figure 3, press on where circle 1 indicates and push the attery cover
forward to the end, then remove the cover (CAUTION: To avoid injury, DO NOT
place your fingers at where circle 2 indicates when pushing the cover).

(4) Replace the attery cover. Place the cover on top front of the attery
compartment, then press on where circle 3 indicates and push the attery cover
downward to the end (CAUTION: To avoid injury, DO NOT place your fingers at
where circle 4 indicates when pushing the cover).

4. Change the Digital Wireless Microphone Channel
When using wireless microphone, there might e interferences from the signals
transmitted y another wireless microphone or other 2.4G wireless appliances near
y. These distur ances can e solved y selecting a different channel.
figure 6
(1) When changing the channel, it is not necessary to turn the power off. Open the
attery cover, and the channel switch is located next to the attery
compartment. There are 8 channel scales on the switch (as shown in the figure 6),
and another 8 channels can e selected in etween scales.
(2) Fitting a slotted screwdriver into the slot, and rotate the switch clockwise or
counter-clockwise to a desired channel. When a new channel is selected, the
microphone connecting LED on the Receiver will link once, which indicates the
microphone and Receiver are reconnected.
(3) To avoid interference and gain the est result, microphone 1 and 2 should e 8
channels apart. If not applica le, keep at least 2 channels apart.
IV. Trou leshooting:
1. No sound
(1) Check if the power to Receiver is well connected.
(2) If the status LED is not lit when the microphone een switched on, check
whether the atteries are properly installed or have enough energy.

slot.
When selecting
the channel, aim
the arrow at the
scale or in
etween two
scales.

(3) The transmitting range is 20 meters, so keep the microphone within the effective
range, or the output audio might e inconsistent.
