[comp.dcom.telecom] NEC "NEAX 2400" Phone System

Does anyone else out there have a NEC "NEAX 2400" phone system with
"6-button Dterm Series II" telephone instruments? We recently moved to
a new office with such a phone system, and unfortunately have received
little information on it. For some unknown reason, the powers-that-be
decided not to even distribute the manuals that were supposed to come
with the phones. I managed to scrape one up, but it still isn't very
helpful; what I think I need is info that is in a "service"-level
manual, or one for the system administrator.

For example, these phones have a row of ten programmable buttons on
them.  We know how to set them up as "speed call" buttons; that's
fairly straightforward. But the phones came with cardboard inserts and
peel-off sticky labels that show those buttons labelled as "OFF", "C",
"CE", the division sign, "X", "-", "+", ".", and "=". So obviously
there is *some* way to set these phones up so that they can be used as
calculators -- they have an LCD display that shows the number you
dial, the number calling you if a local extension, etc. plus another
line showing date and time, so there is a display that would be
suitable for a calculator. But how does one "turn on" this calculator
mode?!? It isn't mentioned in the manual at all!

If anyone can tell me the secrets to comprehending this system, I
would be grateful.
