Information: Residential (or building) installations that do not
provide for brick, concrete, metal, or other dense material between
the DDU and SCU.
Action: In this situation it is possible that the signal emitted by the
DDU will be received by the SCU. This will result in the system
lowering the power of the signal it is emitting; and therefore the area
around the SCU in which a cell phone will function will become
smaller. To improve performance in this scenario, it is important to:
Maximize the height of the DDU
Separate the DDU and SCU horizontally as much as possible
Mount the DDU and SCU in a back-to-back manner.
It is recommended to use 50 meters of cable in between the
DDU and SCU if possible in an effort to vertically and
horizontally separate the system units.

Information: Proper alignment rotation
Action: Make sure the DDU is rotated once completely within the
area available for rotation, and then move through the same rotation
again. DDU alignment is based on optimizing the direction the
DDU is facing after initially establishing the range of signal available
by rotating the DDU in a circle. Once the DDU has been rotated in
a circle and established the level of signal available, it now sets a
threshold based on the surroundings to determine when the LED
will illuminate green. If the DDU is not pointing in a direction that
is within a certain range of the highest signal it encountered since
being in ‘Install’ mode, the LED will not turn green. Additionally,
the LED will not illuminate green if a minimum signal level is not
achieved during the initial rotation.
