Put two enclosed antennas to the antenna connectors (#1) on the rear panel of the Base Station. Turn the
sleeve on each of the antenna connectors clockwise to tighten them and ensure that the antennas are
connected firmly.
Note1:
Transmitting antenna (#1A) must be positioned vertically and be folded completely as 90 degree,
otherwise, it will be caused to weaken the signal.
Note2:
The Base Station should be away from any metal obstructions, walls, and electronic equipment that
can create RF interference. It is highly recommended to place the antenna as high as possible in the
center of the coverage and away from obstructions.
