5. After setting the Dip switch, perform the configuration task.
RF range: RF performance (ranges) depends on the environmental conditions.
That is the reason for listing different ranges, although radio waves can pass through
objects, allowing non line-of-sight communication, obstacles will absorb a portion of
the signal greatly reducing the effective communication range (see Table 4).
Table 4: RF performance range
In order to let radio waves to travel in greatest distances, the waves need to travel
through as few obstacles as possible. Dense obstacles such as concrete, brick or any
