Aligning the units
For the ease of alignment, both Master and Slave units use the install tones in the
same way but with some small behavioral differences. This allows the installer to
install the Slave unit first and carry out the initial alignment with the Master unit if
desired. However, due to the behavioral differences of Master and Slave units, it is
recommended that the Master unit is installed first and the initial alignment carried
out at the Slave unit.
To align the units, proceed as follows:
Procedure 6-28 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

) available in the web interface that displays the state of the link during the
alignment process (up = green, down = red).
