OK, More info needed...

How do you get a red x on a calculator with a green tinted LCD screen?


fred ,i dont know how but it is red,


Did you try the master reset switch under the rubber foot?


randy thaanks for the sugestion which rubber foot?none of them will come out.thanks again.


Turn the bottom of the case of your HP 48 in plain sight and dig out the right upper rubber foot. Underneath (sometimes it's the left foot) there is a small hole with letter R for Reset righ beside it. Use a copper paper clip to press the switch at the bottom of that hole. [VPN]
