System Telephones on the OpenCom 100 / Aastra 800 Add-ons 1.2.1 Upn Adapter A Upn adapter is an adapter with a Upn interface (1) for connecting an additional OpenPhone, and a socket for an AC adapter (2). You can use the AC adapter on the OpenPhone 63 and on the OpenPhone 65. Note: Please operate only the AC adapter with the part no. 4505759 on the Upn adapter (in Britain operate only the AC adapter with the part no. 4510694). 1 2 Upn adapter on the back of the OpenPhone 63 In order to install an adapter, you have to remove the cover from the back of the OpenPhone. Insert the Upn adapter in the socket until it snaps into place. It is possible to install adapters during operation: you do not have to disconnect the telephone from the system in order to do this. Note: In the case of a OpenPhone 65 you can plug a Upn adapter into either of the two sockets. However, you can only operate one Upn adapter on each OpenPhone 65. Using the Upn adapter you can connect an additional OpenPhone 63 or OpenPhone 65as a second telephone. A second telephone connected via a Upn adapter is completely independent of the first one. Connection via adapter is not a parallel connection. When connecting a second telephone, you require a UP cable. Use this cable to connect the additional OpenPhone to the Upn adapter (1) on the first telephone. The 2-wire UP cable must not exceed 30 m in length. Depending on the length of the cable and the type of OpenPhone connected as a second telephone, there may be insufficient feed power. This could result in a decrease of the ringer volume and the open listening/hands-free volume of the second telephone. The feed power can be increased by connecting an external AC adapter (2). 13
