1.
Electro-Magnetic Interference (EMI).
Keep the console several feet away from computer
monitors and TVs.
2.
Radio Frequency Interference (RFI).
If you have other 915/433/868 MHz devices(same
frequency with your device) and communication is
intermittent, try turning off these other devices for
troubleshooting purposes. You may need to relocate the
transmitters or receivers to avoid intermittent
communication.
3.
Line of Sight Rating.
This device is ratedat 300 feet(100 meters) line of sight
(no interference, barriers or walls) but typically you will
get 100 feet(30 meters) maximum under most real-world
installations, which include passing through barriers or
walls.
4.
Metal Barriers.
Radio frequency will not pass through metal barriers
such as aluminum siding. If you have metal siding, align
the remote and console through a window to get a clear
line of sight.
