4.
Status: While optimizing the DDU for installation, you found that
the LED turned green in multiple locations, indicating each had
adequate signal strength. How do you determine which location is
optimal for the DDU?
Action: Look at the signal level indicated on the display on the
bottom of the SCU each time the green light appears on the DDU
during alignment. Mount the DDU in the location as indicated
having the highest signal level. Figure 6.1:“Displayed signal
strength.” below shows an example of the signal strength display.

5.
Status: The DDU and SCU installed properly, but your cell phone
still does not work.
Action: There are three factors that may be affecting coverage as
described below:

Visually inspect the area around the SCU. Ensure that there are
not any large metallic objects directly between the SCU and the
area where cell phone coverage is not adequate. Remount the
SCU so that it is out in the open.

If the signal the DDU is receiving is very weak (although still
strong enough to allow operation), the area around the SCU
within which a cell phone can function will be relatively small.
An effort can be made to improve system performance by
raising or otherwise repositioning the DDU in an effort to
obtain a stronger signal. In Install mode, signal strength is
shown on the SCU display.

check with your cellular provider if your phone is A or B band in
800 MHz. Verify on the back of the SCU or DDU that the system
is SpotCell 100 A or B. It should be the same as your phone.
