1. Line of Sight Rating. This device is rated at 300 feet line of sight (no
interference, barriers or walls) but typically you will get 100 feet
maximum under most real-world installations, which include passing
through barriers or walls.
2. 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.
The following is a table of reception loss vs. the transmission medium.
Each "wall" or obstruction decreases the transmission range by the factor
shown below.
