Safety information6Safety informationNever open the docking station or a mobile unit. Thismust only be done by authorized personnel and is allthe more important for units connected to AC outlets.If units are opened by customers in breach of thisinstruction, the warranty becomes null and void.Set up the unit on an even surface. Lay the cables insuch a way that no-one can stumble over them. Do notuse the DW 800 system in a damp or dustyenvironment.Use the DW 800 system in dry rooms only and keepliquids and small parts which conduct electricity awayfrom the DW 800 system and its connecting sockets.For cleaning the DW 800 system, use a dry cloth only.Do not use any solvents or cleansing agents.The DW 800 mobile units contain a Li-Ionrechargeable battery which must only be replaced byauthorized personnel.The rechargeable battery of the mobile units mustonly be charged in the DW 800 docking station! Never try to charge rechargeable batteries other thanthose of the DW 800 mobile units in the dockingstation!Delivery includesy1 DW 800 docking station with 2 mobile unitsy1 external mains unity1 telephone connecting cable with 2 modular plugsy1 audio cable with two 3.5 mm stereo jack plugsy1 instructions for useFor accessories such as suitable headsets or a wallmount kit, please refer to “Further information” onpage 28.

System overview7System overviewThe DW 800 wireless system:ygives a standard wired telephone the ability forwireless telephony via a headsetyfits any Sennheiser telecom headsetydoes not interfere with normal telephone functionsand you can use your telephone in the usual wayyallows intercommunication between up to fivemobile unitsypermits conference calls between up to fourpersonsyallows voice over IP (internet telephony)The system consists of the DW 800 docking stationand two identical mobile units.A wireless link is established between the mobileunits. For telephoning purposes, one mobile unit hasto stay in the left-hand charging slot of the dockingstation. This mobile unit establishes the telephoneconnection.The second mobile unit, to which a headset isconnected, can be moved around, thus allowingwireless telephony. When the built-in rechargeablebattery of a mobile unit is going flat, the two mobileunits can be exchanged without having to end acurrent call.The DW 800 wireless system is based on state-of-the-art wireless technology. The indoor operating range isup to 150 m. If there is a free line of sight between thedocking station and a mobile unit, the range is up to300 m. The talking time is approx. 12 hours. Thesound quality is excellent – as you have come toexpect from Sennheiser.
