Audio Adapter
12 Add-ons
Using the U
adapter you can connect an additional
pn
T-Comfort 730 Systemtelefon or T-Comfort 830 Systemtelefo-
nas a second telephone. A second telephone connected via a
U
adapter is completely independent of the first one. Connec-
pn
tion via adapter is not a parallel connection.
When connecting a second telephone, you require a UP cable.
Use this cable to connect the additional T-Comfort Systemtele-
fon to the U
adapter (1) on the first telephone.
pn
The 2-wire UP cable must not exceed 30 m in length. Depend-
ing on the length of the cable and the type of T-Comfort Sys-
temtelefon 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 con-
necting an external AC adapter (2).
U
adapters on the communications system can only be
pn
operated on telephones directly connected to the system. A
U
adapter is not permitted on a second telephone.
pn
The audio adapter is an adapter accessory with various sockets
