Installation Instructions
Preparation
The design of the LCF-1440 allows convenient mounting in the dash of
your boat, or it can be mounted on any flat panel at least four inches in
diameter.
To mount the LCF-1440 in the dash, first make sure there is sufficient
clearance behind the panel in the desired location. Also, see that there is
adequate room to connect power and transducer cables. At least 3-1/2 inches
are needed behind the surface of the dash to clear all connectors and wiring.
Recommended Tools and supplies
Recommended tools for this job include: hole saw, drill, drill bit (for
starter hole). Required supplies for this job include: "U" bracket, lock
washers and wing nuts (included).
Mounting the Unit
Cut a 3-3/8 inch diameter mounting hole with a hole saw. A "U" bracket
is supplied to hold the sonar to the dash. Place it over the threaded
studs on the back of the unit and secure it with the lock washers and
nylon wing nuts provided with the unit.

y
(
)
The bracket is designed to secure the unit to a dash with a thickness of
2 mm. If your dash is thicker than 2 mm, the "U" bracket will be too
long. Simply place washers or spacers between the unit and the bracket
until you can tighten the wing nuts and secure the unit it place.
Once the unit is in place, you need to connect it to a power supply, to
the speaker (provided) and to the transducer. All of these elements are
described in the following paragraphs. Refer to the following
illustration as needed.

Speaker
Find a location for the speaker that is protected from the elements, but
still lets you hear it. The most common location is behind the dash. Make
sure to connect the speaker's wires to the same colored wires from the
unit – red to red (from the power source) and black to black (from the
speaker cable). See previous diagram for details. If the 1440's wires won't
reach the speaker, splice ordinary speaker wire to them.
Power Connections
The LCF-1440 works from a 12-volt battery system. For the best
results, attach the power cable directly to the boat's battery. You can
attach the power cable to an accessory or power buss, however you may
have problems with electrical interference. Therefore, it's safer to go
ahead and attach the power cable directly to the battery.
The power cable has two wires, red and black. Red is the positive lead,
black is negative or ground. Make sure to attach the in-line fuse holder
both to the red wire and directly to the power source. This will protect both
the unit and the power cable in the event of a short. It uses a 2-amp fuse.
CAUTION:
Do not use this product without a 2-amp fuse wired into the
power cable! Failure to use a 2-amp fuse will void your warranty.
The black wire is ground and should be connected to the negative side
of the battery or to a suitable ground buss.
This unit has reverse polarity protection. No damage will occur if the
power wires are reversed. However, the unit will not work until the
wires are attached correctly.
Transducer
This unit sometimes comes packaged with either a Skimmer
or podtype transducer. For transducer installation instructions, consult the
separate instruction sheet (part 988-0147-581 for Skimmer-type
transducers, part 988-0147-721 for pod-type).
Lowrance sells many different styles of transducers. If you do not have a
transducer installed, consult your local boat dealer or the Lowrance
service center for assistance selecting the proper transducer for your
boat. (Look inside the back cover of this manual for contact information.)

This unit has the following depth ranges: 10, 20, 40, 80, 160,
320 and 640 feet.
SENSITIVITY
Sensitivity controls the unit's ability to pick up echoes. If you
want to see more detail, try increasing the sensitivity, a little
at a time. There are situations when too much clutter
appears on the screen. Decreasing the sensitivity can reduce
the clutter and show the strongest fish echoes, if fish are
present. As you change the sensitivity setting, you can see the
difference on the chart as it scrolls.
You can change the sensitivity level whether you are in Auto Sensitivity
mode or Manual Sensitivity mode. The adjustment method works the
same in both modes, but it gives you slightly different results.
Adjusting sensitivity in Auto Sensitivity Mode is similar to manually
adjusting a car's speed with the accelerator pedal while cruise control is
on. You can tell the car to run faster, but when you let off the gas the
cruise control automatically keeps you from running slower than the
minimum speed setting.
In your unit, auto mode will let you increase sensitivity to 100 percent, but
the unit will limit your minimum setting. This prevents you from turning
sensitivity down too low to allow automatic bottom tracking. When you
change the setting with auto turned on, the unit will continue to track the
7
Page 12
bottom and make minor adjustments to the sensitivity level, with a bias
toward the setting you selected.
Adjusting sensitivity in Manual Sensitivity Mode is similar to driving a
car without cruise control — you have complete manual control of the
car's speed. In your unit, manual mode allows you to set sensitivity at
100 percent (maximum) or zero percent (minimum.) Depending on
water and bottom conditions, the bottom signal may completely
disappear from the screen when you reduce sensitivity to about 45
percent or less!
Try adjusting sensitivity in both auto and manual modes to see how
they work.
These figures show results of different sensitivity levels. At left, a high
Sensitivity setting shows a display crowded with many return signals.
At right, a lower Sensitivity setting shows only a few strong returns.

GRAYLINE
®
Grayline lets you distinguish between strong and weak
echoes. It "paints" gray on targets that are stronger than a
preset value. This allows you to tell the difference between a
hard and soft bottom. For example, a soft, muddy or weedy
bottom returns a weaker signal which is shown with a
narrow or no gray line. A hard bottom returns a strong
signal which causes a wide gray line.
If you have two signals of equal size, one with gray and the other
without, then the target with gray is the stronger signal. This helps
distinguish weeds from trees on the bottom, or fish from structure.
Grayline is adjustable. The factory default for this unit is 72 percent.
Since Grayline shows the difference between strong and weak signals,
adjusting the sensitivity may also require a different Grayline level.
The level chosen by the sonar unit at power on is usually adequate for
most conditions. Experiment with your unit to find the Grayline setting
that's best for you.

NOISE REJECT and ASP (Advanced Signal Processing)
The ASP (Advanced Signal Processing) feature is a noise
rejection system built into the sonar unit. It constantly
evaluates the effects of boat speed, water conditions and
electrical interference and automatically gives you the best
display possible under most conditions.
ASP is an effective tool in combating noise. In sonar terms, noise is any
undesired signal. It is caused by electrical and mechanical sources such
as bilge pumps, engine ignition systems and wiring, air bubbles passing
over the face of the transducer, even vibration from the engine. In all
cases, noise can produce unwanted marks on the display.
The ASP noise rejection feature is especially useful because it typically
lets you operate the boat at all speeds without adjusting the sensitivity
or other controls.
The ASP feature has three settings — Off, Low and High. When first
turned on, noise rejection is set on low. If you have high noise levels, try
using the high ASP setting. However, if you are having trouble with
noise, we suggest that you take steps to find the interference source and
fix it, rather than continually using the unit with the high ASP setting.
There are times when you may want to turn ASP off. This allows you to
view all incoming echoes before they are processed by the ASP feature.
