Your Delco@ audio system has been designed to operate easily and give
years
of listening pleasure. You will get the most enjoyment out of it if you
acquaint yourself with it first. Find out what your Delco@ system can do
and how to operate all its controls, to be sure you’re getting the most out of
the advanced engineering that went into it.
Be aware that hearing damage from loud noise is almost undetectable until
it is too late. Your hearing can adapt to higher volumes of
sound. Sound that
seems normal can be loud and harmful to your hearing. Take precautions by
adjusting the volume control on your radio to
a safe sound level before your
hearing adapts to it.
To help avoid hearing loss or damage:
0 Adjust the volume control to the lowest setting.
0 Increase volume slowly until you hear comfortably and clearly.
FM Stereo
FM stereo will give you the best sound. But FM signals can only reach
about 10 to
40 miles (16 to 65 km). And, 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 pick up noise from things like electrical storms and power lines.
If
the noise interferes with your listening, try reducing the treble to lessen the
noise.
AM Stereo
This means the Delco@ system can receive C-QUAM@ stereo broadcasts.
Many
AM stations around the country use C-QUAM@ to produce stereo,
though some
do not. If your Delco@ system can get C-QUAM@, your
“STEREO” light will come on when you’re receiving it. (C-QUAM@ is a
registered trademark of Motorola, Inc.).
