OpenPhone 71/73/75 System Telephones Using Your Telephone ■ 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 requirements 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, 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 undesirable marks on your furniture. 9
