Note: See the Administrator’s Guide for information on security settings for phones.
The phones support several security protocols for secure systems.
All security settings for phones are programmed by your system administrator.
Note: The DT820 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
softkeys to see all available options.
The following symbols represent the phone’s directional cursor pad and key pad:
