The only model number I can see is 4424LD+, although I have no idea if that's right. There are no letters engraved anywhere, unfortunately. Any other suggestions?
This is probably a dumb question, but I can't figure out how to correctly label my extension. I get as far as the labeling screen, which shows letters from A-F, and I can't for the life of me figure out how to show the rest of the letters. Can someone please help?
