• 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 requirements
please refer to our website at http://www.aastra.de or http://www.aastra.com. 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.
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, fluorescent
lamps, computers, radios or television sets;
• in dusty places or places subjected to vibrations, shocks or extreme temperature
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.
Cleaning
Simply wipe your telephone with an antistatic or slightly damp cloth. Never use a dry
cloth or a cleaning agent.
