Cassette Deck with Graphic Equalizer - If you have a cassette deck, it is built to work best with tapes that are 30 to 45 minutes long on each side. Tapes longer than that are so thin that they may not work well in this player. Press the PWR button on the radio to turn the system on. The radio will play until a cassette is pushed into the cassette entry door (the tape side goes in first.) Once the tape is playing, use the radio control buttons for volume, balance and fade, just asyou do for the radio. The arrows on the player indicate which side of the tape is being played. Graphic Equalizer The graphic equalizer lets you fine tune bass, mid-range and treble frequencies to your individual taste. The unit has five separate adjustable frequency ranges. To emphasize a frequency, press the top of the button "+" and to de-emphasize a frequency, press the bottom of the button "-." It's best to begin with all the controls in the middle position, then adjust each control as you like. Observe the electronic display for relative frequency emphasis. 3-20
