If Menu Item 116 This -> Other and Menu Item 117 Other -> This are disabled and you cannot program the radio, you have turned on PMG (programmable memory groups). This is so easily done as the [PMG/PW] button is immediately below the [F/MENU] button on the radio's face. You can press that one on your way to the menu and not realize it.
To get the functionality back for programming, press the [PMG/PW] button again to disengage that feature. Now when you access the menu, 116 and 117 will be active and available for you to use.
