The destination screen during Interaction takes more manual instructions – pressing KEY.
The destination ‘VIEW’ or ‘SET’ screen should be reached within 4 steps to select any of the 25 different parameters.
The serial addressing of all the screens related to 25 parameters was changed to Page concept , giving about 8 options on each page. Complicated screen structure & related functions were addressed carefully to reach the destination screen within 4 interactions without increasing the code size.
This was a novel concept in this market segment & was an instant hit !!!!
