Figure 3-63 Beep Interval
When the antenna is aimed, the beep intuitively represents whether the SNR is rising or falling. The higher the SNR rises, the
shorter the period of the beep is heard and the higher the frequency of the beep.
When you change the position of the antenna, SNR averaging settles at the new value and the beeping returns to the
average length so the antenna can again be aimed for rising SNR.
Aiming is complete if moving in any direction results in a falling SNR value (which can be heard as longer periods between
beeps).
:

The range of the average SNR has been limited to values from 5 to 43; therefore, anything over 43 always results in a
short period between beeps and values below 5 always have a long period.

The Antenna Alignment Display (AAD) CLI output is disabled automatically 30 minutes after it is enabled to remove
the load of extra messages on the wireless interface. The default telnet time-out is 300 seconds (5 minutes).
Antenna Alignment Commands
To enable the antenna alignment display from the CLI prompt, enter the following commands:
 ' ' ( ) * ' + , ) , - . ' ,
: Enables display of the local signal, noise and SNR.
 ' ' ( ) * ' + , ) / ) 0 - 1 )
: Enables display of the remote signal, noise and SNR.
 ' ' ( ) * ' + , )
: Enables display of local and remote signal, noise and SNR.
: Use a flat blade screw driver to disconnect and pull out the Serial cable from the enclosure after the antenna
alignment is done. After withdrawing the cables, seal the serial port carefully to avoid water seepage.
