Norstar M7208 display screen looks like most of charactors are missing, unreadable. Changed out phone with out of the box new one, plugged into phone line, same result. Possible problems??
You need to change your contrast, user Feature *7, and press 1 2 3 or 4, when you find the desired contrast level, press hold
Increase the contrast of display of ur phone it might fix the problem
