When you set-up the operating frequency of the ILT and the VLR so far apart that the ILT emission mask and the VLR mask do not overlap as illustrated in Figure 521, the consistency warning message of Figure 522 is prompted by SEAMCAT for you to correct it.

Solution: modify the operating frequencies or the size of the spectrum masks so that an overlap is occurring.
