Using Your Telephone
Overview and Basic Information
General Information
The Aastra 142d is a telecommunications device that you can operate on a communications system
specified as compatible with an OpenMobilityManagement system (OMM).
The newly designed menus enable easy handling and fast access to the many functions and fea-
tures provided by your system.
Make yourself familiar with your telephone equipment. You’ll discover many new functions that
make communication and organization easier.
DECT and GAP
Your handset uses a digital radio connection in accordance with the Digital Enhanced Cordless Tele-
phone (DECT) standard for the connection to the base station. This digital channel guarantees the
highest voice quality possible without static or background noise.
The Generic Access Profile (GAP) and the DECT standard define methods according to which digital
cordless telephones can establish connections. As the GAP standard is not manufacturer-specific, it’s
possible to combine base stations and handsets from different manufacturers with one another.
Basic functions (i.e., making and receiving calls) are always possible when using these combinations.
Other functions (e.g., the display of phone numbers or connection states) may not be available if you
use other manufacturers’ devices, however. For more information, please refer to the user guide
provided by the other manufacturer or ask your system administrator.
Memory Card
The Aastra 142d is equipped with a memory card. The log-in data of the handset, the user name,
the display language, a local telephone book and the ID of the handset (IPEI) are all saved on the
MEM card. This means that if you exchange phones with someone else, you simply take your mem-
ory card out of your own phone and plug it into the other one. You will then have all the data you
need in the new phone and can make calls right away without having to register it on the base sta-
tion again.
The memory card is inserted in a slot in the battery compartment underneath the batteries. For
security purposes, your phone is fitted with an additional battery compartment lock.
In some models, the memory card has already been inserted in the factory. If the memory card has
been supplied separately, you will have to insert it in its slot yourself. This is located in the battery
compartment underneath the batteries. For instructions on how to insert the memory card in the
Aastra 142d, please refer to the section entitled "Installation" below.
