General Information
The OpenPhone 26/27 is a cordless telephone designed for operation in the
OpenCom 100 / Aastra 800 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 com-
munications systems, which means you can use the same handset in different places.
Furthermore, it is possible to operate the handset in communications systems made
by other manufacturers, as long as they meet the GAP standard.
Power Supply
This product requires a 230 V alternating 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 corresponding adapter plug
can be obtained as accessory. Please consult with customer service of your supplier
for this.
Usage
This handset, like any cordless telephone, 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 com-
munication (e. g. medical emergencies).
DECT and GAP
Your handset uses a digital radio connection in accordance with the DECT (Digital
Enhanced Cordless telephone) standard for the connection 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).
