BT Freestyle 750 and 'New Call' on display screen

[mizfiesta]

I purchased a BT Freestyle 750 (single handset) a few weeks ago and I've been happy with my purchase.
I've noticed recently however that the display on the phone is always 'New Call' when in fact there hasn't been one, and I can't get it changed.
I already 'named' the handset 'Home' and originally it did show 'home', but not now. I've tried the following solutions to no avail - 'renaming' the phone - pressing the bottom arrow on the side to see who the last caller was and pressing the back button etc, turning it off at the mains switch - checking any messages left on answering machine.

If any of you know how to solve this problem I'd be grateful, thanks in advance,

I would say that this is a software fault. I would take back, explain that you think display is faulty.
