P7100 Buttons not working

Hi guys, not sure if this is the right place to post this but I've recently got a P7100 and the only thing that seems to work is the scroll wheel, so I'm stuck on the 'choose time zone and set date and time?' screen, only able to alternate between yes and no - I can't press 'ok'!

Are there any techniques to perform a reset on the camera through holding different button combinations etc?

I'm still awaiting mine, but I see from pictures that as with my D5100 there are 2 buttons (Marked with Green Dots) that work as a 2-Button reset when both held together for 2 seconds or so.
Hope that helps.

Thanks Kev, however I can't see any green dots? Looked at the D5100 and it seems to be the Menu and buttons, but there is no on the P7100

D'oh!!

Terribly sorry, I missed the 'P' and mis-read as D7100. My mistake, I apologise.

No worries! We've got 2 P7100s here (I work in a school) and the one that works is fantastic, nifty little piece of gear!

I have same problem: the OK-button does not work. Also the Date and time, Date format and Time zone screen looks same?! It is all the time like Time zone. How can I set time and date format?
