Note:
You can use the visual alignment tool that can be found in the 1ft antenna box for
coarse alignment. Attach it to the antenna and align the antenna untill the remote
antenna can be seen in the center of the eyepiece.

Fine Alignment
Note:
When aligning an antenna, the antenna in the remote node must remain stationary.
Perform Fine alignment first on the local antenna, and only afterwards on the remote
antenna.
The optimum alignment may require several adjustment iterations between the local
and remote antennas.

Connect the DVM to the radio by inserting both red and black probes into their
appropriate positions in the AUX port.
Throughout the alignment procedure, you must compare the actual receive
signal strength indication (RSSI) to the expected RSSI that was calculated during
network link budget preparation (refer to Preparing for Installation on page 20).
Read the receive level (RSSI) using the DVM. The voltage reading will be
between 0 to 1V, indicating the RSSI in dBms. For example, a DVM reading of
0.45V is equivalent to -45 dBm.
