For safety reasons, the telephone should only be sup-
plied with power:
• using the original power supply unit.
Part number:
L30250-F600-C14x (x: 1=EU, 2=US, 3=UK) or
• in a LAN with PoE (Power over Ethernet), which
complies with the IEEE 802.3af standard.
Never open the telephone or a key module. Should you
encounter any problems, contact the responsible ad-
ministrator.
Use only original accessories from Siemens Enterprise
Communications GmbH & Co. KG. The use of other ac-
cessories may be hazardous and will render the warran-
ty, extended manufacturer’s liability and the CE marking
invalid.
The device conforms to the EU directive 1999/5/EC as at-
tested by the CE marking.
All electrical and electronic products should be disposed of
separately from the municipal waste stream via designated
collection facilities appointed by the government or the local
authorities.
Proper disposal and separate collection of your old appli-
ance will help prevent potential damage to the environment
and human health. It is a prerequisite for reuse and recycling
of used electrical and electronic equipment.
For more detailed information about disposal of your old ap-
pliance, please contact your city office, waste disposal ser-
vice, the shop where you purchased the product or your
sales representative.
The statements quoted above are only fully valid for equip-
ment which is installed and sold in the countries of the Eu-
ropean Union and is covered by the directive 2002/96/EC.
Countries outside the European Union may impose other
regulations regarding the disposal of electrical and electron-
ic equipment.

Location of the telephone
• The telephone should be operated in a controlled environment with an
ambient temperature between 5°C and 40°C.
• To ensure good speakerphone quality, the area in front of the micro-
phone (front right) should be kept clear. The optimum speakerphone
distance is 50 cm.
• Do not install the telephone in a room where large quantities of dust
accumulate; this can considerably reduce the service life of the tele-
phone.
• Do not expose the telephone to direct sunlight or any other source of
heat, as this is liable to damage the electronic components and the
plastic casing.
• Do not operate the telephone in damp environments such as bath-
rooms.

Trunk keys (on multi-line phones only)
The programmable keys on multi-line phones function as line keys. Each
key that is assigned the function "line" is handled as a line. This means up
to three lines can be configured.
A distinction is drawn here between primary, secondary and phantom
lines. Each of these line types can be used on a private or shared basis.
Primary line
All multi-line telephones have a primary line. This line can be reached in the
usual manner via your public phone number. Incoming calls are signaled on
this line.
Secondary line
The secondary line on your phone is used as a primary line by another sub-
scriber of the line trunk group. Your primary line, which is configured on an-
other telephone in the line trunk group, simultaneously functions as the
secondary line on that telephone.
Phantom line
Phantom lines are not used as primary lines by any telephones in the line
trunk group. Phantom lines are established when the number of lines pro-
vided by a communications system exceeds the number of available
telephones.
Line utilization
•Private line: A line that is used by a single telephone. This line cannot
be used as a secondary line by another telephone.
•Shared line: A line that is configured on multiple telephones. The line
status is displayed for all telephones that share this line. If, for example,
a shared line is being used by a telephone, a status message indicating
that this line is busy is displayed on all other telephones (page 18).
•Direct call line: A line with a direct connection to another telephone.
To avoid conflict between individual multi-line phones, the functions
"Do not disturb" and "Call forwarding" can only be used for the prima-
ry line.
