PROG (Program): Press this button to play a station you have programmed on the radio preset pushbuttons. The radio will only seek preset stations with a strong signal that are in the selected band. When a cassette tape is playing, press this button to play the other side of the tape. When a CD is playing in the CD changer, press this button to go to the next available CD, if multiple CDs are loaded. Press this button to switch between FM1, FM2, AM, or XM1 or XM2 (if equipped), or a cassette tape or CD. The cassette or CD must be loaded to play. Available loaded sources are shown on the display as a tape or a CD symbol. Radio Reception AM The range for most AM stations is greater than for FM, especially at night. The longer range can cause station frequencies to interfere with each other. Static can occur on AM stations caused by things like storms and power lines. Try reducing the treble to reduce this noise. Q SOURCE R: FM Stereo FM stereo will give the best sound, but FM signals will reach only about 10 to 40 miles (16 to 65 km). Tall buildings or hills can interfere with FM signals, causing the sound to fade in and out. Q SEEK R: Press the up or the down arrow to go to the next or to the previous radio station and stay there. The radio will only seek stations with a strong signal that are in the selected band. When a cassette tape or CD is playing, press the up or the down arrow to fast forward or reverse. XM™ Satellite Radio Service XM™ Satellite Radio Service gives digital radio reception from coast to coast. Just as with FM, tall buildings or hills can interfere with satellite radio signals, causing the sound to fade in and out. The radio may display NO SIGNAL to indicate interference. Q VOLR (Volume): Press the up or the down arrow to increase or to decrease the volume. 3-132
