This site is home to the NEC Dealers Association (NECDA) Administration Training Videos. A free username and password is available from your NEC Installing Dealer if they are a member of NECDA. If you don't login you will only see the two sample videos under "Free Samples". With a username and password the menu options under "NECDA University" will expand to allow access to all 27.

All videos are done in HD video. If your bandwidth supports HD, I recommend you use 720P and full screen.
