Removing faceplate on a Olympus 770SW???

[The ROC]

Hello,

I just bought the Olympus 770SW for watersport activities and was wondering if there was anyone who may know whether the front faceplate that is held down by the 3 screw can be removed so that if there was any water underneath it can dry. I did unscrew the 3 screws but the faceplate doesn't seem to want to come off.

Thanks in advance for the help.

Cheers.
