■
Keep fluids and chemicals away from the telephone and its accessories.
■
Use only the AC adapter plug included in the delivery (product code 4516000;
in Britain operate only the AC adapter with the part no. 4516001) where
necessary.
■
Do not use AC adapter plugs that show visible damage (e. g. cracks in the
housing).
■
Connected headsets must conform with the standard DIN EN 60 950-1, Point
6.2 (“Safety of information technology equipment including electrical business
equipment”).
For more information on this and a list of headsets which meet these require-
ments please refer to our website at www.Aastra-DeTeWe.de. You can also
contact a headset manufacturer of your own choice, of course.
■
Use a shielded CAT-5 Ethernet cable (STP cable, Shielded Twisted Pair cable) to
connect an IP telephone to a Local Area Network (LAN).
■
Make sure that no one can trip over the telephone cables.
1.1.2 Installation Site
Do not install the telephone or its accessories
■
near water, moisture or in damp locations;
■
near sources of heat or in direct sunlight;
■
in unventilated rooms;
■
near devices that generate strong magnetic fields, electrical devices, fluo-
rescent lamps, computers, radios or television sets;
■
in dusty places or places subjected to vibrations, shocks or extreme temper-
ature fluctuations.
Place the telephones on a non-slip surface. The surface finish of your furniture may
affect the telephone’s pedestals, softening them and causing them to leave unde-
sirable marks on your furniture.
