Repeat steps 4 and 5 until you achieve an optimal link,with all four Signal LEDs solidly lit. This ensures the bestpossible data rate between the airFiber X radios.7. Lock the alignment on both airFiber X antennas bytightening all the nuts and bolts.8. Observe the Signal LEDs of each airFiber X radioto ensure that the values remain constant whiletightening the nuts and bolts. If any LED value changesduring the locking process, loosen the nuts and bolts,finalize the alignment of each airFiber X antenna again,and retighten the nuts and bolts.Refer to the following chapters of this User Guide fordetails on the airFiber Configuration Interface:• “Dashboard” on page 17• “Wireless Tab” on page 21• “Network Tab” on page 25• “Services Tab” on page 29• “System Tab” on page 33• “Tools” on page 37Installer Compliance ResponsibilityDevices must be professionally installed and it is theprofessional installer’s responsibility to make sure thedevice is operated within local country regulatoryrequirements.The Output Power, Antenna Gain, Cable Loss*, TX Frequency,and RX Frequency fields are provided to the professionalinstaller to assist in meeting regulatory requirements.* Cable Loss includes loss due to the Duplexer(s).
