Taking apart my Philips DECT 2111S/11

[merel]

Hi,

I am trying to take apart my Philips DECT 211 phone, because the speaker has managed to come loose and it's driving me crazy, rattling in my ear when I'm on the phone. Problem is, after taking out the screw at the bottom/back of the phone, I cannot open it up (and I don't want to force anything). Anyone ever taken this thing apart? The user's manual does not show how.

Thanks for your help,

Merel
