for example... I am pressing 5, but 4 comes up.. any idea what is going on..
I would try clean starting the unit, regardless what model you have. If that doesn't correct the problem , please provide more information.
As Lana noted external cleaning of the keypad per the user manual is a first step. As the keyboards and Keypads are different for each model, and to help us better understand the issue, which device is this for?
