Receiver signal is noisy or contains extraneous sounds with transmitter on.
- Check if the battery is low.
- Check for other sources of RF interference causing interference.
- If using a guitar or other musical instrumenl, check the connections. If multiple transmitters are used together, it is possible that multiple transmitters will operate on the same frequency.
- Find the same frequency point, close the others, and only one is left.
- Signal may be too weak. Reposition the antenna. Move them closer to the transmitter if possible.
Noise from receiver with the transmitter off.
- Reposition the receiver and perform another “drill” test and observe the RF indicator. If audio loss persists, mark these “dead spots” in the performance area and avoid them during the performance.
