
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.


shall be 5-15CM and the best angle is 45
degrees.

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 mi-
crophone!
