Hi Andrea,
this posting from W2ZK (from the archives) gives the answer I hope...

"If the two receivers are sharing the main
antenna path, putting the sub receiver on a
higher-frequency band than main may result in
signal loss in the sub. This is due to sharing of the
main receiver´s low-pass filters. If you select an
incompatible band combination, the K3 briefly
displays USE AUX as a warning. To avoid sub
receiver signal loss, use the sub´s AUX input."
