Is it safe to sell my used modem?

Hi all,

This modem has seen all my personal data flow through it over the last year.

I've reset it by holding that tiny "reset" button in with a paper clip for ten seconds (manufacturers instructions to reset it).

Does this mean it's safe to sell, and no buyer could get my email, passwords, banking details, etc from it?

Thanks
