What do you mean by "the contents in the middle paragraph of the instruction manual [0002,0003] are non-technical terms, and the applicant should delete them"?

This means that your two paragraphs are not technical content, either you have advertising content, which does not meet the writing requirements of the manual, or you have written something that will bring commercial effects in the future after promotion. In short, they should not appear in the manual, so you can delete them. This paragraph number is assigned to you by the examiner according to your content, which generally refers to the second and third paragraphs.
