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 been received by the Receiver.
(4) If the feedback noise appears when the volume is too high or the microphone is
too close to the speaker, turn the volume down.
(5) For best result, keep the microphone to the sound source in between 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 been 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 batteries
(1) When the status LED keeps blinking after the microphone is on, it indicates the
battery energy is running low, so please replace the batteries.
(2) As shown in figure 3, press on where circle 1 indicates and push the battery 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. Change the Digital Wireless Microphone Channel
When using wireless microphone, there might be interferences from the signals
transmitted by another wireless microphone or other 2.4G wireless appliances near
by. These disturbances can be solved by selecting a different channel.
figure 6
(1) When changing the channel, it is not necessary to turn the power off. Open the
battery cover, and the channel switch is located next to the battery
compartment. There are 8 channel scales on the switch (as shown in the figure 6),
and another 8 channels can be selected in between 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 blink once, which indicates the
microphone and Receiver are reconnected.
(3) To avoid interference and gain the best result, microphone 1 and 2 should be 8
channels apart. If not applicable, keep at least 2 channels apart.
IV. Troubleshooting:
1. No sound
(1) Check if the power to Receiver is well connected.
(2) If the status LED is not lit when the microphone been switched on, check
whether the batteries are properly installed or have enough energy.
