RECOMMENDATIONS
1- Avoid putting the main machine in a blind angle when it is used. This is for keeping signal receiving
in good condition.
2- Don`t throw fall, toss, cast the handling microphone when it is used. In case damage it seriously.
3- Please keep the machine from direct sunshine or rains, and put it in a place as far as possible from
the magnetic field.
4- Don`t open it yourself, because there is high voltage in it.
9. REPAIR WITH SIMPLE FAULT
Turn on the receiver, but the indicator is not lighted:
Make sure if the power cable is well fixed. Is the socket in good condition?.
Is the fuse blown?.
When you speak , the "AUDIO" light twinkles, but no sound output:
Make sure if the volume keep in lowest place, or the audio cable is not fixed well.
The effective signal-receiving distance becomes close. And signal receiving is not well:
Perhaps you have not put out the antennas.
Perhaps you should change a new battery.
Perhaps the receiver is not put i right place.
Perhaps there is a strong magnetic field in your surroundings.
Timbre becomes bad:
Perhaps the voltage of the battery is not enough. You need change.
Perhaps there are the same frequency signals in your surroundings.
