CAUTION
If, when in the Synchronized or Registered state, the tone varies wildly,
there may be interference or a fast fading link. Installing in this situation
may not give a reliable link. Investigate the cause of the problem.
Aligning the units
To align the units, proceed as follows:
Procedure 5-18 Align Master and Slave
1
Adjust the elevation and azimuth of the Master unit to achieve an approximate
visual alignment with the site of the Slave unit.
2
Adjust the elevation and azimuth of the Slave unit to achieve an approximate
visual alignment with the site of the Master unit.
3
Without moving the Master unit, adjust the elevation and azimuth of the Slave
unit to achieve the highest pitch installation tone.
4
Without moving the Slave unit, adjust the elevation and azimuth of the Master
unit to achieve the highest pitch installation tone.
5
Repeat steps 3 and 4 as necessary to fine tune the alignment.
NOTE
To achieve best results, make small incremental changes to elevation and
azimuth.
There is a graphical installation screen (see Graphical install on
page 6-75) available in
the web interface that displays the state of the link during the alignment process (up =
green, down = red).
