“0” represents a flat response.

iX-Bass
Press iX-BASS (5) to activate the iX-BASS feature. When listening to music at low volume
levels, this feature will boost the bass and treble ranges to compensate for the characteristics
of human hearing. When this feature is activated, “iX-BASS On” will appear in the display.

When the equalizer function is activated, the most recently selected bass/treble levels cannot
be adjusted. When the equalizer function is not active, the unit will return to the most recently
selected bass and treble levels.
Liquid Crystal Display (LCD)
The liquid crystal display (LCD) panel (8) displays the frequency, time and activated functions
of the unit, including a combination audio level/disc indicator, which appears as dual disc icons
with circular bar graphs depicting the audio signal. In addition, the display contains a receive
signal indicator that depicts the relative strength of the incoming broadcast frequency.
NOTE: LCD panels may take longer to respond when subjected to cold temperatures for
an extended period of time. In addition, the visibility of the numbers on the LCD may
decrease slightly. The LCD display will return to normal when the temperature increases
to a normal range.
