![Velox LE Installation and Operations Manual 862-02411 February 04 8-9 Frequency Channel Plan D (FCC Compliant) Fr equency plan D allows independent control of transmit and receive frequencies. This allows a flexible frequency plan and can be used to overcome interference in the 2.4GHz and 5.8 GHz ISM bands. The frequencies that can be used in the lower or upper sub-bands can be selected in 1 MHz increments. Performance degradation can be expected when operating using channel plan D mode with the chosen frequencies close to the sub-band edges, i.e. a choice of one of the high frequencies in the lower sub-band and one of the lower frequencies in the upper sub-band. The allocation of Channel plan D frequencies is shown in Table 8-4, Table 8-5, Table 8-6 and Table 8-7 below. The Velox LE 24/5850 RFUs have up to four different sets of minimum and maximum frequencies, which are determined by the data rate setting of the RFU. Only channel frequencies that are FCC compliant can be selected through the configuration software. The channel frequency ranges are programmed into the radio firmware and cannot be adjusted by the user. The radios were tested and approved for FCC compliance with the frequency ranges in Table 8-4 below. Table 8-4.

The changes can be made via software using the Velox LE NCT/GUI or an SNMP client application.

During this period, the link will not be available. Changing the RFU modulator type does not support Auto Recovery thus; the modulator type of the remote station must be changed before the modulator type of the local station is changed. RF Power Output Options The RFU is designed for use in countries that have adopted FCC standards. It is possible to adjust the output power on the RFU using the supplied NCT software or a SNMP Management application. The FCC standards for the Velox LE 2410 unit require a limited output power as stated in the FCC Notice (USA only) in the front matter of the manual.](https://usermanual.wiki/Aviat-Networks/3ECJ68A4D.Users-Manual/User-Guide-398821-Page-93.png)
