AUDIO: Push and release the AUDIO knob until BASS, MID (midrange) (without Bose®), or TREB (treble) displays. Turn the knob to increase or to decrease the tone. The display shows the bass, midrange (without Bose®), or treble level. If a station is weak or has static, decrease the treble.

To adjust the bass, midrange (without Bose®), or treble to the middle position while it is displayed, push and hold the AUDIO knob. The radio produces one beep and adjusts the display level to the middle position.

To adjust all tone and speaker controls to the middle position, push and hold the AUDIO knob when no tone or speaker control is displayed.

ALL CENTERED displays, a beep sounds, and the display level adjusts to the middle position.

AUTO EQ (Automatic Equalization): Press this button to select customized equalization settings designed for country/western, jazz, talk, pop, rock, and classical. Selecting CUSTOM or adjusting the tone controls, returns the EQ to the manual mode.

The radio saves separate AUTO EQ settings for each preset and source.

If the radio has the Bose® audio system, the AUTO EQ settings are either CUSTOM or TALK.
