I want the manual for Ipod touch gen 7, how

Try this link: iPod touch User Guide – Apple Support (UK) which has a web version of the user manual. There is a downable copy, from Apple Books, but it is not available everywhere, try this link: https://books.apple.com/book/id1567104841. If it doesn't work, you will have to make do with the online version.

Alternatively, you may find out what you need to know by asking here.

Apple - Support - Manuals (AU)

Seems the manuals go by iOS ?
