Sony Bravia LCD Radio problem

Ok this may sound silly, but here goes :

i need to know how to turn the radio off ... my grandma somehow turnd it on and now even when the tv is turned off the radio still works, worst part is i didnt even see the tv i just know that this is the remote :

and please even if you have a different bravia/other sony tv with a radio or a different remota, please post ...





The tv is Sony Bravia 40 inch ( i think ), maybe if someone has a similiar model or atleast similiar function can just write how to turn the radio off ?? thanx
