you can use the feature.
3 Check with your system manager to be sure this
feature is administered on your voice terminal.
4 You may have an older version of System 75; thus,
some features may operate differently from the
procedures described in this guide. Check the
section below on "System 75 Version Notes" for
ways in which these features work differently.
See your system manager for a list of feature access
codes for features assigned to your voice terminal.
Then, write the codes in this guide.
1 Check with your system manager to be sure your
voice terminal is administered correctly.

not go on or flashes rather than goes on steadily,
the voice terminal is not communicating with the
PBX.
4 Find a working voice terminal of the same type as
your own. Unplug this voice terminal from its
modular wall jack. Plug your voice terminal into
that jack and check if it gets dial tone.
5 If your voice terminal still does not work, plug the
working voice terminal (of the same type) into
your modular wall jack. If the working voice
terminal has dial tone, your own voice terminal is
faulty. See your system manager.
