7. TROUBLESHOOTING
1. Turn on the receiver, but the indicator is not lighted
- Make sure if the power cable is well fixed. Is the socket in good conditions?. Is the fuse blown?.
2. When you speak, the "AUDIO" LED twinkles but no sound output
- Make sure if the volume keep in lowest place, or the audio cable is not fixed well.
3. The effective signal receiving distance becomes close and signal receiving is not well.
- Perhaps you should change the batteries
- Perhaps the receiver is not put in right place
- Perhaps there is a strong magnetic field in your surrounding
4. Timbre becomes bad.
- Perhaps the voltage of the batteries is not enough. You need to change them.
- Perhaps there are the same frequency singal in your surrounding. Do not usetwo devices with the
same frequency at the same time in a place. (Separate them at least 100m)
