Mem Card; The Headset Socket - Aastra 142d User Manual

Using the Aastra 142d Telephone
basic functions (telephoning, accepting calls) are always available in these combi-
nations; other functions (e.g. displaying the call number on the display, displaying
connection charges) which your OpenCom 100 / Aastra 800 communications
system provides along with your mobile unit, may not be available with other
manufacturers' communications systems. Please consult the corresponding man-
ufacturer's user guide or contact your system administrator.
Information on Transmission Quality
■
Due to digital transmission within the frequency range used – even within
range depending on the structural environment – dead spots can result. In this
case, transmission quality can be lessened by increased and brief transmission
gaps. A slight movement outside the dead spot will re-establish the usual
transmission quality. When a caller goes out of range, the connection is
disconnected.
■
In order to avoid radio-related interference with other electronic devices, we
recommend as great a distance as possible (minimum of 1 m) between the
charger or mobile unit and other devices (e.g. radios, loudspeakers, etc).

MEM Card

The Aastra 142d is equipped with a memory card (MEM card). The MEM card stores
the check-in data of the device, the user name, the display language, a local
directory and the device identification (IPEI = International Portable Equipment
Identity). This means that when switching devices by inserting the MEM card into
another device, this data is available on the other device and calls can be made
immediately (without checking in again).
The MEM card is inserted into the battery compartment below the battery. For
safety reasons, the device has an additional battery compartment lock. If the
MEM card is enclosed separately, you have to insert it in the battery compartment
below the battery. Please refer to the chapter Aastra 142d with MEM Card starting
on page 12 for information on how to insert the MEM card into the Aastra 142d.

The Headset Socket

The mobile unit has a 2.5 mm socket for connecting a headset. The Aastra headset
accessory only must be used in order to comply with the electrical values.
