General Information
The OpenPhone 26/27 is a cordless
telephone designed for operation in
the OpenCom 100 communications
system. In addition to convenient
softkey control of system features,
this telephone also offers a variety of
features that allow you to make calls
more easily. You can also operate
your handset in other communica-
tions systems, which means you can
use the same handset in different
places. Furthermore, it is possible to
operate the handset in communica-
tions systems made by other manu-
facturers, as long as they meet the
GAP standard.
Power Supply
This product requires a 230 V alter-
nating current power supply. This
product can only be switched off by
removing the adapter plug from the
mains socket.
The mains supply voltage in some
countries is 110 V. The correspond-
ing adapter plug can be obtained as
accessory. Please consult with cus-
tomer service of your supplier for
this.
Usage
This handset, like any cordless tele-
phone, operates using radio signals,
which do not always guarantee a
connection being established under
all circumstances. For this reason,
you should never rely solely upon
any cordless telephone for essential
communication (e. g. medical emer-
gencies).
DECT and GAP
Your handset uses a digital radio
connection in accordance with the
DECT (Digital Enhanced Cordless
telephone) standard for the connec-
tion to the base station. The digital
channel guarantees superior voice
quality without static or background
noise. For signalling between the
communications system and the
handset, the OpenPhone 26/27 uses
the Generic Access Profile (GAP).
The Generic Access Profile (GAP) and
the DECT standard define processes
