If you use the optional engine coolant heater before starting your engine,
your heating system will produce warmer air faster to heat the passenger
compartment in cold weather. See “Engine Coolant Heater” in the Index.
Audio Systems
Your Delco@ audio system has been designed to operate easily and give
years
of listening pleasure. But 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.
Increase volume slowly until you hear comfortably and clearly.
FM 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.
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.
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. (C-QUAM@ is
a registered trademark of Motorola,
Inc.) If your Delco@ system can get C-QUAM@, your
“STEREO” light will
come on
when you’re receiving it.

Downloaded from www.Manualslib.com manuals search engine NOTICE:
Before you add any sound equipment to your vehicle - like a
tape player, CB radio, mobile telephone or two-way radio - be
sure you can add what you want.
If you can, it’s very important
to do
it properly. Added sound equipment may interfere with the
operation
of your vehicle’s engine, Delco@ radio or other
systems, and even damage them. And, your vehicle’s systems
may interfere with the operation
of sound equipment that has
been added improperly.
So, before adding sound equipment, check with your dealer and
be sure to check Federal rules covering mobile radio and
telephone units.
