moving the left up makes more lows, right side is highs. middle is mids and so on.
As pointed out above, the seven sliders on your radio are the graphic equalizer - basically just a fancy tone control. Each slider allows you to increase or decrease the volume of the sound in that particular frequency range. It is called "graphic" because the positions of the sliders form a line graph of the frequency response. The sliders on the left side affect the low (bass) frequencies, the middle sliders affect the midrange, and the right side affect high (treble) frequencies. So, your photo shows lows and highs "boosted" (increased) with "flat" midrange (neither boosted nor cut). This is basically what a "loudness" control would do - boost the high and low frequencies because they aren't as audible at low volume settings.
Here is a good tutorial on equalization with a chart of what sounds fall into which frequency ranges: http://www.dak.com/reviews/Tutorial_frequencies.cfm.
