The camera has a high sensitivity
microphone. Keep the camera at least 10 feet
away from the receiver. If the camera must be
within 10 feet of the receiver, keep the
volume down.
Place the camera and/or receiver antenna at a
new angle or readjust its position to make an
improvement.
Remove obstacles between the camera and
receiver that might affect the signal (e.g.,
furniture, cabinets, and walls.)
Relocate the camera closer to the receiver.
