Chapter 1: Introducing Your 4620/4620SW/4621SW
IP Telephone
Introduction
This chapter introduces you to the layout of the 4620/4620SW/4621SW IP Telephone. It
provides a description for each functional button and other phone characteristics, briefly
describes each 4620/4620SW/4621SW application, and provides basic instructions for
navigating display screens.
Note:
Note: The 4620 and 4620SW SW IP Telephones have the exact same appearance,
user interface, and functionality. The phones do have somewhat different internal
circuitry, and, unlike the 4620, the 4620SW supports Russian and multi-byte
characters (Chinese, Japanese, and Hebrew), as covered in Selecting an
Alternate Language in Chapter 6: 4620/4620SW/4621SW IP Telephone Options.
When the term “4620” is used anywhere in this document, the information also
applies to the 4620SW, unless otherwise noted.
Note:
Note: The 4620SW and the 4621SW are almost exactly the same telephone. Both
telephones have the same appearance, user interface, and functionality. The
phones do have somewhat different internal circuitry, and the 4621SW has a
special backlighted display. Like the 4620SW, the 4621SW supports Russian and
multi-byte characters (Chinese, Japanese, and Hebrew), as covered in
Selecting an Alternate Language
in Chapter 6: 4620/4620SW/4621SW IP
Telephone Options. When this document uses the terms “4620” and 4620SW,”
the information also applies to the 4621SW, unless otherwise noted.
