OpenPhone 28
Using Your Telephone
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 28 uses the
Generic Access Profile (GAP).
The Generic Access Profile (GAP) and
the DECT standard define proce-
dures used by digital cordless tele-
phones to establish connections.
The GAP standard is not manufac-
turer-specific so it is possible to com-
bine the communication systems
and handsets of different vendors.
The basic functions (making and re-
ceiving calls) are always possible
with in these combinations, but
other functions provided by your
OpenCom 100 communications sys-
tem together with your handset
(e.g. display of call numbers or call
charges) may not be available when
communications systems produced
by other manufacturers are used.
Additional Notes
Depending on the digital transmis-
sion in the frequency range used
and also on the technical environ-
ment within the range of coverage,
silent zones may occur. In this case,
transmission quality can be dimin-
ished by multiple, short transmis-
sion gaps. Slight movement out of
the silent zone will restore typical
transmission quality. The connection
will be lost if the handset is moved
out of range.
In order to avoid radio coupling into
other electronic equipment, we rec-
ommend the maximum possible dis-
tance (min. 1m) between the hand-
set and other devices (e.g. radios,
loudspeakers etc.).
Before using the handset, people
with hearing aids should note that
radio signals can couple into hearing
aids and if strong enough can cause
an unpleasant buzzing sound.
