Optio S5z Menu lock

Hello All,
I have a Optio S5z digital camera, regrettable my Daughter has some how managed to Lock out the Menu screen, that is, when you press the menu button a Padlock icon appears on the screen, thus unable to access the menu tables.
There is no mention of this in the Operation Manual, I have tried the Pentax website to no avail, does anyone possible know now to unlock the menu please.
Many thanks,

Pat Whelan.

Hi Pat, and welcome to the forum..

I'm pretty sure that you've got it set to "Green Mode", so a quick look through the manual for that should let you get back out of it.

EDIT: Press the "Quick Button", to get out of Green Mode... I looked it up.

Cheers

Liam
