* 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, near-presence of objects (for example, trees, walls, signage, and so on) that may induce

multipath fading. As a result, actual performance varies for each instance.
