6. Slave Aim the Slave at the Master to achieve the strongest
signal level on the Remote LED Display of the Slave.
Note: Values on the LED Displays are displayed in
negative (-) dBm. For example, 67 represents a received
signal level of -67 dBm. Smaller numerical values indicate
stronger received signal levels. For example, a reading of
49 is stronger than a reading of 55.
Note: Maximum signal strength can best be achieved
by iteratively sweeping through both azimuth and
elevation.
7. Master Aim the Master at the Slave to achieve the strongest
signal level on the Remote LED Display of the Master.
Note: If the Overload LED lights up, refer to the
airFiber AF-5/AF-5U User Guide at:

8. Repeat steps 6 and 7 until you achieve a symmetric link, with
the signal levels within 1 dB of each other. This ensures the
best possible data rate between the airFiber radios.

9. Lock the alignment on both airFiber radios by tightening the
nuts and bolts.
10. Observe the Local and Remote LED Displays of each airFiber
radio to ensure that the values remains constant while
tightening the nuts and bolts. If any LED value changes during
the locking process, loosen the nuts and bolts, finalize the
alignment of each airFiber radio again, and retighten the nuts
and bolts.
11. For each airFiber radio, close the port cover and ensure that the
Ethernet cable stays in the cable feed slot.
