Add-ons (with & without Adapters)
Telephone’s Functions and Features
OpenCom 100. To avoid such dam-
age when connecting add-ons, you
must first discharge the static elec-
tricity from your body. Work only in
an antistatic environment. If possi-
ble, use conducting pads or anti-
static mats.
U
pn
Adapter
A U
pn
adapter is an adapter with
a U
pn
interface (1) for connecting
an additional OpenPhone, and a
socket for an AC adapter (2). You
can use this so-called U
pn
adapter
on the OpenPhone 63 and the
OpenPhone 65.
Note:
Please only operate the AC
adapter (part no. 4505759) on the
U
pn
adapter.
U
pn
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
U
pn
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 (OpenPhone 63 or
OpenPhone 65) from the communi-
cations system in order to do this.
CAUTION!
Do not damage
the adapter cover.
Note:
In the case of an
OpenPhone 65, you can plug the
U
pn
adapter into either of the two
sockets. However, only one U
pn
adapter can be operated for each
OpenPhone 65.
Using a U
pn
adapter you can connect
an additional OpenPhone 63 or
OpenPhone 65 as a second terminal.
A second terminal connected via a
U
pn
adapter is completely independ-
ent of the first one. Connection via
adapter is not a parallel connection.
When connecting a second terminal,
you require a UP cable. Use this cable
to connect the additional Open-
Phone to the U
pn
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
terminal, there may be insufficient
feed power, which could result in a
decrease of the ringer volume and
the open listening/hands-free vol-
ume of the second telephone. The
feed power can be increased by con-
necting an external AC adapter (2).
