Welcome

Welcome to the user guide for the Dialog 4223 Professional and Dialog 4225 Vision system telephones in the Ericsson MD110 Communication System, D4 mode. 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 4223 Professional and Dialog 4225 Vision 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.

The latest version of this user guide can be downloaded from:

http://www.ericsson.com/enterprise/library/manuals.shtml

If you would like to practise the handling of the phone, you can try the “Ericsson Enterprise End User Training On Telephones”, available at:

http://ericsson.tripnet.se/learngatestore/courses/EndUser/ Usertool/index.htm.

To start practising, select the option “Ericsson Enterprise eLearning”, and then select your type of phone.

Note: Dialog 4223 Professional and Dialog 4225 Vision are system telephones, i.e. they can only be used for an Ericsson private branch exchange that supports these types of phones.
