How do I view a Facebook page as someone else?

[Terence]

I know how to view my timeline as someone else, but I have several Facebook Pages I am admin of and it doesn't seem to have the same interface for viewing those as someone else. A quick web search turns up hundreds of pages on viewing personal timelines, but not pages. How do I go about doing that?
Peter, "Facebook sucks" isn't an answer. And "people are getting off of it" is demonstrably untrue. You may be right in that it isn't possible but I don't particularly trust your answer, given the rest of your comment.

As to Mad's answer, that shows me how to use Facebook as my page, which isn't what I'm asking. I know how to do that. I want to view my page as a different user like I can view my timeline as a different user.

You cant. Facebook sucks anyway and people are getting off of it because it blows.

Hello,
When you are logged into Facebook on your main username. Just click on the gear symbol in the top right corner of the screen and you are able to choose to view Facebook as one of your pages.

However you will only be able to access people that are associated with that page. You are unable to access information from other places that haven't been linked to your page.

Sorry for the bad news.
