b) Menu Settings

To select the menu settings, push the rotary control (3) briefly or for a longer time to call the two levels of the menus.
The first level serves to set more frequently used functions, while the second level only contains functions that are
needed less often.
Choose the options for the respective settings by turning the rotary control.
Depending on the source (radio unit, USB playback etc.) that is currently active, only some functions may
be available.
Menu items - Push the rotary control (3) briefly
BAS > TRE > BAL > FAD > LOUD > EQ > STEREO/MONO > LOC > BEEP
• BAS controls the low frequency range
• TRE controls the high frequency range
• BAL controls the volume ratio between the right and left speakers
• FAD controls the volume ratio between the front and rear speakers
• LOUD ON/OFF
LOUD ON >> The loudness function is active.
LOUD OFF >> The loudness function is inactive. The sound is not influenced.
At low volumes the human ear does not perceive very low and very high sounds well. An increase of the
frequency range for low volume (loudness correction) counteracts this effect and the music replay sounds
more natural.
