Overview of the system Overview of the system The 2020 D Tourguide System offers optimum digital speech transmission for guided tours e. g. in factories or museums. The use of RF transmission allows freedom of movement for all members of the group. Six preset intermodulation-free receiving frequencies offer high flexibility and adaptability. In Europe, the 2020 D Tourguide System is approved in the frequency range 863 – 865. See the overview on page 50.
Overview of the system The HDE 2020 D stethoset receivers The stethoset receivers are easy to use and comfortable to wear. The built-in display shows all the important information at a glance (receiving channel, reception quality, charge status of the built-in lithium-polymer rechargeable battery as well as the currently set volume). The rocker button allows fast and easy setting of the desired channel. The system can be expanded at any time by adding additional stethoset receivers.
