* Actual RF range performance is subject to a number of installation-specific variables including, but not restricted to
ambient temperature, relative humidity, presence of active interference sources, line-of-sight obstacles, and near-
presence of objects (for example, trees, walls, signage, and so on) that may induce multipath fading. As a result, actual
performance varies.
