Please use the other included documentation on parts of your communications system. This documentation
is on the Comfort Pro product CD.
DECT and GAP
A digital radio connection is established between the mobile unit and the base station (Radio Fixed Part, RFP)
in accordance with the DECT standard (DECT = Digital Enhanced Cordless Telecommunications). The digital
channel ensures the best voice quality without static or background noise. The Generic Access Profile (GAP)
is used for signalling between the communications system and the mobile unit.
The Generic Access Profile (GAP) and the DECT standard define procedures according to which digital
cordless telephones can establish connections. The GAP standard applies independent of manufacturer,
meaning that communications systems and mobile units of various manufacturers can be combined. The
basic functions (telephoning, accepting calls) are always available in these combinations; other functions
(e.g. displaying the call number on the display, displaying connection charges) which your Comfort Pro
communications system provides along with your mobile unit, may not be available with other manufacturers'
communications systems. Please consult the corresponding manufacturer's user guide or contact your
system administrator.
Information on Transmission Quality
■
Due to digital transmission within the frequency range used – even within range depending on the
structural environment – dead spots can result . In this case, transmission quality can be lessened by
increased and brief transmission gaps. A slight movement outside the dead spot will re-establish the
usual transmission quality. When a caller goes out of range, the connection is disconnected.
■
In order to avoid radio-related interference with other electronic devices, we recommend as great a
distance as possible (minimum of 1 m) between the charger or mobile unit and other devices (e.g. radios,
loudspeakers, etc).
■
As is the case with any cordless telephone, the mobile unit uses radio signals which do not guarantee a
connection under all circumstances. This is why you should never completely rely on cordless telephones
for essential communication (e.g. for medical emergencies).
