What is the purpose of LNA (CH---) at Digital Set-up?

When manual tuning is conducted in LNA On, the channel scanned will be keep at LNA On for user viewing and you will see LNA (CH--) On. If we set default as OFF during manual tuning, the channel scanned will always stored LNA OFF & you will see LNA (CH---) Off. As a result the picture quality will not be at best level.
User can change it and stored it independently for each channel.
