• DO NOT swap the antenna while power is on.
• If you use an antenna that has an exposed metal part, DO NOT touch the antenna with you hands/body (Static electricity can damage the LNA).

Monitoring range

• You shouldn't receive near high power transmitters, even if it's not in the range that you are monitoring.

Diagnostic

• Try to listen to local radio. Try it with AMP both ON and OFF.
• Try to capture and replay a non-rolling-code. Try it with AMP both on and off.
