AmSt
The AmSt button is just below the PWR button. Push this when you tune to
an AM station that broadcasts in stereo. Your STEREO light
will
come on
when you're receiving AM stereo. If you push AmSt and there is no more
noise,
it
means the station is weak. You'll hear the station better if you don't
use AmS. Just push the AmSt button again to cancel stereo.
NOTE: Your Delco system may be able to receive C-QUAM@ stereo
broadcasts. Many AM stations around the country use C-QUAM@ to produce
stereo, though some do not. C-QUAM@ is a registered trademark of Motorola
lnc. If your Delco, system can get C-QUAM@ signals, your STEREO light will
come on when you are receiving stereo.
Press the PWR button on the radio to turn the unit on. The radio
wi l l play
until a cassette is pushed into the cassette entry door (the tape side goes in
first.) The cassette deck 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.
Once the tape is playing, use the WOL, BAL and FADE controls on the
radio. The arrows indicate which side of the tape is being played.
Equaker
Boost the bass, emphasize a voice in a song, brighten the treble-your
equalizer enables you to adjust five separate sound frequencies to your
individual taste.
