It seems that you want to know how to make the required adjustments in order to begin a scheduled recording.
The HDS-600RS can record two channels simultaneously or watch one channel while recording another. It is designed to use two satellite LNB inputs. It will operate with a single input but many of the advanced features as described above will not be available.
You can check your "tuner mode" under Menu/Settings/Technical Info/Signals & Network Info/tuner mode.
Please be aware that you can only make this setting once. If you need to change the "tuner mode" you have to perform a factory reset Menu/Settings/Factory reset.
Hope this helps.
