OpenPhone 26/27 Using Your Telephone
used by digital cordless telephones
to establish connections. The GAP
standard is not manufacturer-spe-
cific so it is possible to combine the
communication systems and hand-
sets of different vendors. The basic
functions (making and receiving
calls) are always possible with these
combinations, but other functions
provided by your OpenCom 100
communications system together
with your handset (e. g. display of
call numbers or call charges) may
not be available when communica-
tions 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 charg-
ing station / handset 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.
