sequence was unsuccessful and the
numbers did not match either of the
codes. In this case, the audio system
will remain in the SECURED mode.

Understanding Radio Reception
F M
Stereo
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.
AM
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 also pick up noise from things like
storms and power lines. To lower this
noise, try reducing the treble level.
AM Stereo
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, Inc. If your
Delco@ system can get C-Quam@
signals, your stereo indicator light will
come on when you are receiving it.
