6 Menu operation
You can access all functions and settings for the TECHNIRADIO SOLAR via the menu.

menu is divided into submenus and, depending on the selected source (DAB+ or FM),
contains different menu items or functions which can be enabled.

asterisk ( * ) highlights the current selection. To go back one step, briefly press
the Menu/Info button.
To close the menu: Press the Menu/Info button several times (depending on
which submenu you are in) until the current radio channel is displayed again.
Settings are not saved until the Select button is pressed. If the Menu/Info key
is briefly pressed instead, the settings will not be accepted and saved.

7 DAB+ (digital radio) function
7.1 What is DAB+?
DAB+ is a new digital format through which crystal clear sound with no noise can
be heard. In contrast to conventional analogue radio stations, DAB+ can be used to
broadcast multiple stations on one and the same frequency. This is referred to as
an ensemble or multiplex. An ensemble is comprised of the radio station, as well as
several service components or data services, which are broadcast individually by the
radio stations. For further information go to www.dabplus.de or www.dabplus.ch .
7.1.1 Data compression
By doing so, digital radio takes advantage of the properties of human hearing. The
human ear does not perceive sounds which are found under a specific minimum
volume. Data which are found under the so-called audibility threshold can, therefore,
be filtered out. This is possible because, in a digital data stream, the relevant relative
volume for other units is saved for every unit of information. Moreover, in an audio
signal, the quieter parts are superimposed by louder ones at a specific limit value.
All the sound information below the threshold of hearing in a piece of music can be
filtered out of the signal to be broadcast.
This leads to a reduction of data in the data stream to be transmitted, with
no perceptible difference in sound for the listener (HE AAC v2 process as a
supplementary codification process for DAB+).
