Welcome
Welcome to the user guide for the Dialog 4220 Lite and Dialog
4222 Office system telephones in the Ericsson MD110
Communication System. It is a state-of-the-art business
communications system. Its alliance of features and facilities
effectively improves communications for virtually any kind of
organization.
There is a line of telephones designed for easy use in every
situation to take full advantage of these advanced features and
facilities.
Function descriptions that do not include speaking in the handset,
are described off-hook, if nothing else is stated. Instead of pressing
the Clear key, you can always replace the handset.
Some markets use differing codes for some functions. In this guide,
all functions are described using the most common code. The
markets and their differing code is shown as a side note.
The user guide describes the facilities of the Dialog 4220 Lite and
Dialog 4222 Office system telephones as they are programmed at
delivery from the factory. There may be some differences in the way
your phone is programmed. Please consult your system
administrator if you need further information.
