Why is the MultiMux losing my stored configuration changes?

Downline Loading may be enabled on the remote MultiMux. This would cause your local MultiMux settings to be overwritten by the settings stored in the remote MultiMux's Downline Load Channel Parameters configuration screen. You must either disable Downline Loading on the remote mux by placing dip switch 1 of the remote mux in the down (closed) position, or you must make the configuration changes on the remote MultiMux.
