Does the Spectrum Management section of the PTP670 User Guide help at all?

If you are in Dynamic Spectrum Optimization mode, you can bar channels that you don’t want to use. In Fixed Frequency mode, you can select the exact frequency that you want to use. Take note of the warning in the User Guide though:
Transmit and receive frequencies can be fixed in a PTP 670 wireless link. Once fixed frequency mode is configured, the spectrum management software will not attempt to move the wireless link to a channel with lower co-channel and adjacent-channel interference. Therefore, this mode of operation is only recommended for deployments where the installer has a good understanding of the prevailing interference environment. Care must also be taken to ensure that the frequency allocations at each end of the link are compatible.
Fixed frequency mode is not available in regions where radar detection is required by the regulations.
