Talk buttons or keypad not working
When you press a button, the button does not move or people cannot hear you talking while the talk button is pressed down.
Unresponsive Number Pad
If there is any sticky residue around the buttons, clean that residue off with a cotton swab and alcohol; check for function afterwards.
