Most manufacturers of this type of product (consumer/commercial) will not
provide service literature to anyone but their authorized servicers. Check
with NEC for the nearest authorized servicer. You MAY be able to talk him or
her into trying to get you a manual, but expect to pay at least $250 for it.
Then, without training and the proper equipment (including the software to
set the unit up), your friend may still not be able to get it going
properly.

Considering the cost of those units, it would might even be a good
investment to pay to have it repaired. Especially when you consider that it
likely contains many parts that won't have any cross to something you can
pick up at the local electronics supply house, and NEC probably won't sell
parts to you, either.

Good luck, no matter which way you go.
