Treble

Lightly press the TREB knob in order to extend the knob. Rotate the knob clockwise in order to increase the treble. Rotate the knob counterclockwise in order to decrease the treble. If the station is too weak or noisy, turn the TREB knob down. When this knob is used, the radio's AUTO TONE setting will switch to manual and the AUTO TONE display will go blank.

Push these knobs back into their stored positions when not in use.
