  Open the battery box correctly and install the battery. Attention shall be paid to the cathode and anode of the battery.

Turn the power switch on microphone to “ON”. If the power indicator lamp does not flash or always lights, inspect 

whether the battery voltage is insufficient or the polarity of battery is installed oppositely. 

  Before using wireless microphone, please extend the rod antenna and make it vertically upward, so as to reach a 

better receiving effect.

Adjust the microphone volume knob on the audio amplifier and adjust its position according to the sound volume 

when singing, so as to reach the ideal effect. 

  If you have to use wireless microphone temporarily during the singing process, you can put the microphone switch in 

mute status; once using is stopped, you can turn the microphone switch in off status. The microphone will pick up 

sound to amplify it and input to the horn of the audio amplifier no matter it is in mute or off status. 

The receiving antenna shall not get access to the metal surface, wall or other obstacles; if it is too closed to them, 

the performance will be reduced dramatically, influencing the receiving effect. 

The effective using distance of wireless microphone is within 30m, please never use it beyond the effective range in 

order not to affect the singing effect; when the electricity quantity of battery is reduced or the wireless interference 

signal of the using environment is too strong, the using distance shall be shortened accordingly.

To reach the best singing effect, the distance between mouth and microphone shall be 5-15CM and the best angle is 

45degrees. 

After the microphone is used for a very long time and lacks of electricity, the indicator lamp for electricity insufficiency 

will light. Please timely change the battery in order not to affect the singing effect.

Please never use the microphone in the same frequency point for singing within short distance since it may cause 

silence or interference noise. 

If you have purchased more than two sets of active audio amplifiers matched with wireless microphone from the 

company and intend to use them together, please select the varieties in different standard frequencies. If the 

frequency is identical, two sets machines can not be used until they are separated from each other for 100m, so as 

to avoid mutual interference and other unnecessary troubles! Never get the machine to VCD/CD/DVD and other 

equipments with strong interference frequency when they are used, so as to avoid mutual interference between the 

same frequency and directly affecting the normal work of wireless receiving of microphone!
