question

On a Cisco 525G2 phone, how do I send a page?  I've already set up paging groups, and have softkeys on our other phones to initiate a page, but I can't figure out how to do it on the 525 phone, which is our main receptionist phone, and the one that would probably do it most frequently.  Is there any kind of list of shortcuts on how to use special features like paging, call park, etc.?
