(such as Call
Forward code or

code) written in

Solution
Reread the procedure and try again.
For many features you must lift the handset before you can
use the feature.
Check with your System Manager to be sure this feature
is administered on your voice terminal.
You may have an older version of the System 75 software
so that some features may have slight differences from the
procedures described in this guide. Check the section
below on “Version Notes” for ways in which these
features work differently.
See your System Manager for a list of Feature Codes for
features assigned to your voice terminal. Then, write the
codes in this guide.

Check with your System Manager to be sure your voice
terminal is administered correctly.
Make sure that the handset and line cords at your voice
terminal are securely connected at both ends.
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.
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.
