	The volume of receiver or amplifier is too small	Turn aloud properly
3. Receiving distance is too near	Distance of wireless microphone and receiver is too far	Go back to the service areas
	Antenna of receiver is not pulled out	Pull out
	Battery power insufficient	Replace the batteries
4. Sound worsen	Battery power insufficient	Replace batteries
	Pronounce too loud and mouth close too much	Leave mouth a little

Main Features

Using UHF 550-568 MHz frequency to avoid the interference.
Using multilevel high frequency and middle frequency narrowband filter, so as to dispel any possible interference signals.
Using special ALC circuit to avoid losing your own sound due to big volume.
With the low consumption components, the life of the battery will be much longer.
With the power indication circuit in the handhold microphone, so you will know when to replace the battery.
All use quartz crystal oscillating circuits, so the frequency is very steady.
With the decreasing back-out whistle function, it can decrease the whistle efficiently.
The tonality is quite good with the excellent crystal and components.

Microphone Operation

Turn to "OFF" position of the switch, open the battery box cover, install the batteries (DC 9V) correctly, then cover back.
Turn to "ON" position of the switch when using, turn to "SIN BY" position if don't using temporarily so that noise could not go through.
