[Plugin: WP Customer Reviews] Pagination, how it works?

Hi, I don’t understand how pagination works on this plugin. I am supposed to provide the number of reviews in the shortcode and it should create the pagination itself?

In the settings I read:
NUM=”3″ will show a maximum of 3 reviews (without pagination), how do I activate the pagination?

Thanks!
