1.1 About this User Guide
This guide describes the available features of the DT390 cordless phone
when it is connected to MX-ONE™.
The DT390 cordless phone is designed for use in an office environment
where messaging is not needed. It is intended for telephony and has
high quality voice.
Depending on the version and configuration of the exchange that your
phone is connected to, some of the functions and features described in
this user guide may not be available. There can also be some differ-
ences in the way your phone is programmed. Please consult the system
administrator if you need further information. Some markets use differing
codes for some features. In this guide the features are described using
the most common codes. The latest version of the user guide can be
downloaded from www.aastra.com.
1.2 Preparing for Use
Before using your phone for the first time, you have to charge and
connect the battery, see Installation on page 97.
Note: Place the phone in the charger and charge it for at least one hour
before using it the first time.
1.3 IPEI and IPDI Codes
Your phone has a unique IPEI code (International Portable part Equip-
ment Identity), and a unique global GAP identity number for the DECT
registration (IPDI). The IPEI and IPDI codes are used for network
subscription of the phone.
At delivery, the phone’s IPEI and IPDI codes are identical, and either of
them can be used for network subscription.
Note: If the phone is replaced by another phone using the easy replace-
ment procedure, the IPDI code changes. If the IPEI and IPDI
codes differ, the IPDI code should be used for network subscrip-
tion.
To look up the IPEI and IPDI codes, do the following:
