See the Administrator’s Guide for information on security settings for phones.
The DT920/DT920S and DT930/DT930S phones support several security protocols
for secure systems.
Depending on the model of your phone and the configuration of your system, not all
features may be available on your phone.
All security settings for phones are programmed by your system administrator.

The DT920 phones have a smaller screen display than is shown in the
examples in this section. You may have to scroll using the cursor pad and
