For all of you who want manuals and are having a hard time obtaining them check out
https://www.tech-man.com Do a quick search for NEC, scroll down and you'll see NEC Telecom and a list of hundreds of manuals for NEC. By the way, I am in no way affiliated with them. I use this site whenever I need a manual because it's fast and easy. They do charge something like 10 bucks for a days worth of downloading. So download all you can within that day
