show the same greatest number of bars, mount the DU facing in the direction where
the number of bars was displayed for the longest period of time during rotation.
5. It is recommended that various outside roof and exterior wall locations, and locations
within the building be tested to identify the best DU location. On the upper floors of
tall buildings, it may be necessary to tilt the DU down to get the strongest signal.
The bar display on the DU will help you identify the location where the received signal
strength is strongest. See DU signal level indicators: on page 35 for details on the
signal level indicator.
Mount the DU in the location that has the highest indicated signal level. Five bars is
maximum.
Note: The displays on the DU automatically shut off after the system has been powered
for 20 minutes. If this time-out occurs during the location or allignment of the DU, simply
re-activate the display by either cycling the system power off/on or disconnecting and
re-connecting the DU’s coaxial cable.
6. Proceed to mounting the DU and installing the coaxial cable (see “Mounting the DU
on page 19”).
After the DU is mounted, it is recommended that you temporarily re-connect the CU
to the DU and quickly verify that the expected greatest number of bars (as found in
steps 4 and 5) is displayed.
