This must only be done by authorized personnel and is all the more important for units connected to AC outlets. If units are opened by customers in breach of this instruction, the warranty becomes null and void. Set up the unit on an even surface. Lay the cables in such a way that no-one can stumble over them. Do not use the DW 800 system in a damp or dusty environment. Use the DW 800 system in dry rooms only and keep liquids and small parts which conduct electricity away from 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-Ion rechargeable battery which must only be replaced by authorized personnel. The rechargeable battery of the mobile units must only be charged in the DW 800 docking station!
Never try to charge rechargeable batteries other than those of the DW 800 mobile units in the docking station!
1 DW 800 docking station with 2 mobile units
1 external mains unit
1 telephone connecting cable with 2 modular plugs
1 audio cable with two 3.5 mm stereo jack plugs
1 instructions for use For accessories such as suitable headsets or a wall mount kit, please refer to Further information on page 28. Delivery includes 6 System overview System overview The DW 800 wireless system:
gives a standard wired telephone the ability for wireless telephony via a headset
fits any Sennheiser telecom headset
does not interfere with normal telephone functions and you can use your telephone in the usual way
allows intercommunication between up to five mobile units
permits conference calls between up to four persons
allows voice over IP (internet telephony) The system consists of the DW 800 docking station and two identical mobile units. A wireless link is established between the mobile units. For telephoning purposes, one mobile unit has to stay in the left-hand charging slot of the docking station. This mobile unit establishes the telephone connection. The second mobile unit, to which a headset is connected, can be moved around, thus allowing wireless telephony. When the built-in rechargeable battery of a mobile unit is going flat, the two mobile units can be exchanged without having to end a current call. The DW 800 wireless system is based on state-of-the-
art wireless technology. The indoor operating range is up to 150 m. If there is a free line of sight between the docking station and a mobile unit, the range is up to 300 m. The talking time is approx. 12 hours. The sound quality is excellent as you have come to expect from Sennheiser. 7 Operating elements Operating elements For the illustration of the operating elements please refer to the fold-out.

Do not recharge the rechargeable battery of a mobile unit during a conference call as this will end the conference mode immediately!
Setting up the DW 800 system for conference calls To initiate the conference mode:
Place a mobile unit into the left-hand charging slot of the docking station. This mobile unit becomes the master mobile unit and is able to control the other mobile units participating in the conference call. Initiate an outgoing call or accept an incoming call
(see Telephoning with the DW 800 system on page 16). Press the program key on the master mobile unit and keep it pressed for four seconds. The master mobile unit starts beeping in a high tone three times a second, thus indicating conference initialization mode. The mobile unit belonging to the master mobile unit automatically participates in the conference call without the necessity of making further settings. 19 Advanced settings 20 Within one minute after the last mobile unit was placed into the docking station:
If an additional mobile unit is to participate in the conference call, place into the right-hand charging slot of the docking station. The mobile unit starts beeping the same way as the master mobile unit, indicating that the mobile unit has joined the conference call. it Repeat the last step for up to three mobile units. Press the program key on the master mobile unit and keep it pressed for four seconds. All mobile units stop beeping. The conference initialization mode is ended and the conference call begins. conference Note:

Intercom works independently of the telephone line. You require a separate headset for every mobile unit. Setting up the DW 800 system for an intercom conference To initiate the intercom conference mode:
Place a mobile unit into the left-hand charging slot of the docking station. This mobile unit becomes the master mobile unit and is able to control the other mobile units in the intercom system. 21 Press the program key on the master mobile unit and keep it pressed for four seconds. The master mobile unit starts beeping in a high tone three times a second, thus indicating conference initialization mode. Within one minute after the last mobile unit was placed into the docking station:
Place a mobile unit into the right-hand charging slot of the docking station. The mobile unit starts beeping the same way as the master mobile unit, indicating that the mobile unit has joined the intercom conference. For larger intercom conferences:
Repeat the last step for up to four mobile units. Press the program key on the master mobile unit and keep it pressed for four seconds. All mobile units stop beeping. The conference initialization mode is ended. Note:
The conference initialization mode ends auto-
matically one minute after the last mobile unit is placed into a charging slot or the maximum number of participating mobile units is reached.

Press the hook key on the master mobile unit. Note:
When intercom is ended, the corresponding mobile units automatically return to the operating status they had before intercom started. It is not possible to re-enter intercom once it has been exited. Upon delivery, the two mobile units of a set are already paired, i.e. they automatically recognize each other and do not interfere with other wireless systems used in the vicinity. You do not have to pair the two mobile units. If you switch off a mobile unit and switch it on again, the mobile units of a paired set automatically recognize each other. However, if you have to exchange one of the two mobile units of a set for a new one, e.g. because it is 23 damaged, the two mobile units will not recognize each other until they are paired manually as follows:
Place both mobile units into the charging slots . The mobile units are set to standby. The logo on the hook key is backlit in blue, thus indicating correct contact to the docking station. On both mobile units, press the program keys and the hook keys at the same time and keep them all pressed for four seconds. After the two mobile units have been paired successfully, the LED flashes once in green, then in red and in orange. If pairing was not successful, the LED flashes in red every five seconds instead.
