SEEK TYPE: Press this button to go to a station with
the last selected PTY TYPE and the last selected PTY
will appear on the display, if it is not already showing. 
If a station with the selected PTY is not found, the radio
will return to the original station. If both SEEK TYPE
and TRAF are on, the radio will search for stations with
traffic announcements and the selected PTY.

PRESET: Press this button to play a station you have
programmed on the radio preset buttons.

MODE: Press this button to choose AM, FM1 or FM2.
If a cassette tape or compact disc is playing, it will stop
and the radio will play.

VOL: Press the up or down arrow to increase or
decrease volume.

MUTE: Press this button to silence the system. 
Press it again to turn on the sound.

The range for most AM stations is greater than for 
FM, especially at night. The longer range, however, can
cause stations to interfere with each other. AM can pick
up noise from things like storms and power lines. Try
reducing the treble to reduce this noise if you ever get it.

FM stereo will give you 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 come and go.
