1997 LINCOLN TOWN CAR Owners Manual

52When the radio waves are reflected off objects or
structures, the reflected signal cancels the normal
signal, causing the antenna to pick up noise and
distortion. Cancellation effects are most prominent
in metropolitan areas, but also can become quite
severe in hilly terrain and depressed roadways.
To minimize these conditions, a stereo/mono blend
circuit has been incorporated into this system. This
feature automatically switches a weak stereo signal
to a clearer monaural signal, which improves the
quality of reception.
Several sources of static are normal conditions on
AM frequencies. These can be caused by power
lines, electric fences, traffic lights and
thunderstorms.
Another reception phenomenon isStrong Signal
Capture and Overload. This can occur when
listening to a weak station and when passing
another broadcast tower. The close station may
capture the more distant station, although thedisplayed frequency does not change. While passing
the tower, the station may switch back and forth a
few times before returning to the original station.
When several broadcast towers are present
(common in metropolitan areas), several stations
may overload the receiver, resulting in considerable
station changing, mixing and distortion.
Automatic gain control circuitry for both AM and
FM bands has been incorporated into this system to
reduce strong signal capture and overload.
All About Radio FrequenciesThe Federal Communications Commission (FCC)
and the Canadian Radio Telecommunications
Commission (CRTC) establish the frequencies that
AM and FM radio stations may use for their
broadcasts. The allowable frequencies are, AM: 530,
540...1600, 1610 kHz in 10 kHz steps; FM: 87.9,
88.1...107.7, 107.9 MHz in 0.2 MHz steps.

Not all frequencies will be assigned to a given area.
This radio will tune to each of these frequencies
using manual tune and no fine tuning is necessary
as radio stations may not use other frequencies.
Some FM radio stations advertise a ªrounded-offº
frequency which is not the frequency they actually
broadcast on. For example, a radio station that is
assigned a frequency of 98.7 MHz may call itself
ªRadio 99º even though 99.0 MHz is not an
allowable FM broadcast frequency.

Controls and FeaturesThe Climate Control SystemElectronic Automatic Temperature
Control SystemThe Electronic Automatic Temperature Control
(EATC) module is located at the center of the
instrument panel and operates only when the key is
in the ON position.The EATC feature maintains the temperature you
select and automatically controls the airflow for
your comfort. It also allows you to override the
automatic operation with manual override buttons.

56The controls for the automatic electronic
climate control
To turn your EATC on, push the AUTOMATIC
button or any of the six override buttons along the
bottom of the control.
To turn your EATC off, press the OFF button.
When the system is off, the display window will be
blank (dark) except when OUTSIDE TEMP has
been selected. Then, OUTSIDE TEMP and the
temperature will appear in the window.
If you select AUTOMATIC, the system will
automatically determine fan speed and airflow
location. If an override button is selected, your
selection determines airflow location only. Fan
speed remains automatic unless you override it by
rotating the vertical thumbwheel located at the
extreme right of the control panel.
To change the temperature in the display window,
select any temperature between65ÊF(18ÊC) and
85ÊF(29ÊC)using the BLUE (cooler) or RED
(warmer) buttons. The Electronic Automatic
Temperature Control will do the rest.

If you want continuous maximum cooling, push the
BLUE button until60ÊF(16ÊC) isshown in the
display window. Your EATC will cool at maximum
and disregard the60ÊF(16ÊC)setting until you
select a warmer temperature with the RED button.
If you want continuous maximum heating, push the
RED button until90ÊF(32ÊC) isshown in the
display window. Your EATC will provide maximum
heat regardless of the90ÊF(32ÊC)setting until you
select a cooler temperature with the BLUE button.
The display window tells you how the system is
operating. It will indicate the selected temperature
and the operating function you have chosen; AUTO
or one of the six manual overrides. It will also
indicate manual (thumbwheel) control of the fan
speed with the
Hsymbol. The display window
with all possible displays and their positions are
shown here. Normally not all are shown at the
same time but are included here to familiarize you
with the names and symbols.
Automatic operationPush the AUTOMATIC button and select the
desired temperature. The selected temperature and
AUTO will be shown in the display window. The
EATC will automatically heat or cool to achieve the
set temperature. Under normal conditions, your
EATC will need no additional attention.

58When in AUTOMATIC and weather conditions
require heat, air will be sent to the floor. But, a
feature is included in your EATC to prevent
blowing cold air to the floor if the engine coolant is
not warm enough to allow heating. For a short
time the fan will be at low speed and air directed
to the windshield. In 3-1/2 minutes or less, the fan
speed will start to increase and the airflow will
change to the floor area.
If unusual conditions exist (i.e., window fogging,
etc.), the six manual override buttons allow you to
select special air discharge locations. A thumbwheel
allows you to adjust the fan speed to suit your
needs.
Temperature selectionThe RED and BLUE buttons at the upper left of the
Control are for temperature selection. The RED
button will increase the set temperature and the
BLUE button will lower the set temperature.
Pressing a button and releasing it will change the
set temperature one degree. Holding either button
in will rapidly change the temperature setting in
one degree increments to either65ÊF(18ÊC)
(BLUE) or85ÊF(29ÊC)(RED).Then, the set
temperature will jump 5 Ê and stop at either60ÊF
(16ÊC)which is maximum cooling or90ÊF(32ÊC)
which is maximum heating.
The average temperature range used is between
68ÊF(20ÊC) and78ÊF(26ÊC).Changing the
temperature setting by several degrees outside this
range or overriding to60ÊF(16ÊC) or90ÊF(32ÊC)
will not speed up the heating or cooling process.

Temperature displayThe selected temperature displayed in the window
can be set for either Ê F or Ê C . Your car may have
an English/Metric (E/M) Button to change your
speedometer from miles to kilometers. When
pressed, this button also changes the temperature
display. With or without an E/M Button, the
temperature display can also be changed to Ê F or
Ê C using the MAX A/C and DEFrost override
buttons.

To change the temperature display to Ê F or Ê C ,
press and hold the MAX A/C and DEF Buttons at
the same time for 3/4 second. The display will
change. If you continue to press the two buttons,
the display will continuously switch between Ê F and
Ê C . If the temperature display does not agree with
the speedometer on vehicles with an E/M button,
pressing the E/M button will make them agree.Fan speed and thumbwheelYour EATC automatically adjusts the fan speed to
the existing conditions. You must push
AUTOMATIC for automatic fan speed operation. To
control the fan speed yourself, use the thumbwheel
which will cancel the automatic fan speed control.
The thumbwheel is located at the extreme right
side of the EATC control panel. It is a vertical
control marked with a fan symbol. Rotate up for HI
and down for LO speeds.
