Here are some suggestions that could solve the problem and prevent you from having to be without your unit!
* Inspect the buttons: Make sure that no buttons are stuck in the down position. If one is stuck, wiggle the button to free it back to the normal position.
* Debris in the contacts: In case there is dirt or other debris covering the contacts inside the keypad, press down on the button in question and wiggle it to try to restore its function.
