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 devices that generate strong magnetic fields, electrical devices, fluo-
rescent lamps, computers, radios or television sets;

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.

Simply wipe your telephone with an antistatic or slightly damp cloth. Never
use a dry cloth or a cleaning agent.
