The storage temperature for your unit is from -4 degrees to +167 degrees
Fahrenheit (-20 degrees to +75 degrees Celcius). Extended storage in tempera-
tures higher or lower than specified will damage the liquid crystal display in your
unit. This type of damage is not covered by the warranty. For more information,

INTRODUCTION
Thank you for purchasing a Lowrance sonar. Your X-45 is a high quality
sonar designed for both professional and novice fishermen. These units
have an automatic feature that finds and displays the bottom, fish,
structure, and more! All you have to do is press the on key. However, if
you wish to fine tune the unit, simply press the menu key. The X-45 has
powerful features available through easy-to-use menus.
Installinganoptionalspeed/temperaturesensorletsyouviewthesurface
water temperature, boat speed, and distance log. The X-45 also takes
advantage of the optional BroadView™ transducer. See page 12 for
information on the FishView™ feature that uses this transducer.

INSTALLATION - Bracket
Youcan install theX-45 on thetop of adash or froman overhead withthe
suppliedbracket. Itcan also be installed inthe dashwith anoptional IDA-
3 or IDA-4 mounting kit. If you use the supplied bracket, you may be
interested in the optional GBSA-1 swivel bracket kit. This converts the X-
45's gimbal bracket to a swivel mount which can be used on the dash or
overheadmounting positions.Installation instructionsfor thein-dash and
swivel mounting kits are supplied with the adapter kits.
Mount the X-45 in any convenient location, provided there is clearance

of plywood on the back side of thin panels to reinforce the panel. Make
certain there is enough room behind the unit to attach the power and
transducer cables.

POWER CONNECTIONS
The X-45 works from a 12 volt DC system only. For the best results, run
thepowercabledirectlytotheboat’sbattery. Keepthepowercableaway
fromotherboatwiring,especiallytheengine’swires. Thiswillgivethebest
isolation from electrical noise. If the supplied cable is not long enough to
reachthebattery,splice#18gaugeinsulatedwiretoit.Ifyoudoextendthe
powercable,makecertaintoattachthein-linefuseholdersuppliedwiththe
X-45to thebatteryor powersource.This willprotect boththeunit andthe
power cable in the event of a short. Use only a 3-amp fuse.
IMPORTANT!
Do not use this product without a 3-amp fuse wired into the power cable!
Failure to use a 3-amp fuse will void your warranty!
You can also attach the power cable to an accessory or power buss,
however, you may have problems with electrical interference.
This units 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.

If you ever get lost in the menus, simply press the ON/CLEAR key. This
clears the menus from the screen.
Menus change depending on the mode the unit is in. For example, if the
automatic mode is turned off, the sensitivity menu changes from “AUTO
SENS” to “MAN SENS.” Other messages may appear in menu boxes or
new menus can appear, again depending on previous selections.
On the screen shown on the previous page, the lamp menu is showing.

When the X-45 is first turned on, the automatic feature is enabled. This
feature automatically adjusts the unit’s range and sensitivity according to
waterconditions. Italwayskeepsthebottomdepthdisplayedinthelower

the down arrow key increases the range.
After you select the desired range, press the
ON/CLEAR key to clear the display. If you wait a few seconds, it
automatically clears.
The X-45 has the following ranges:
10, 20, 40, 60, 120, 240, 480, and 900 feet.
and
5, 10, 20, 40, 60, 100, 200, and 300 meters.
NOTE: The depth capability of the X-45 depends on the transducer
installation, water and bottom conditions, and other factors.
RANGE - Upper and Lower Limits
TheX-45letsyouchangetheupperandlowerrangelimitswhenit'sinthe
manual mode. This lets you "zoom" in on segments of the water as small
as 10 feet. In other words, you can set the upper limit to 25 feet and the
lowerlimitto35feet,regardlessofthebottom
depth. This in essence, gives you a 10 foot
zoom. You can choose any segment of the
water, as long as the distance between the
upper limit and lower limit is 10 feet (10
meters) or more.
To change the upper limit, first make certain

to increase it. When you have the limit set, wait a few seconds and the
menu will scroll off the screen’s left side. Pressing the ON/CLR key also
clears it.
ZOOM
The zoom feature enlarges all echoes on the screen. If the unit is in the
automatic mode, it tracks the bottom signal, always keeping it near the
bottom of the screen. This lets you see small detail, at the same time

SENSITIVITY
Thesensitivitymenuletsyoucontroltheunit’sabilitytopickupechoes. A
lowsensitivitylevelexcludesmuchofthebottominformation,fishsignals,
and other detail. High sensitivity settings lets you see features, but it can
also clutter the screen with noise and other unwanted signals. Typically,
the best sensitivity level shows a good, solid bottom signal with grayline.
The X-45 adjusts the sensitivity level to keep a solid bottom signal on the
screen. It adds a little extra when it’s in the automatic mode. This gives
it the capability to show fish and other detail. However, situations occur
whereitbecomesnecessaryto increaseordecreasethesensitivitylevel.
Typically, this occurs when you wish to see more detail, so you need to
increasethesensitivity. Theproceduretoadjustitisthesamewhetherthe

GRAYLINE ®
Graylineletsyoudistinguishbetweenstrongandweakechoes. It“paints”
gray on targets that are stronger than a preset level. This shows the
difference between a hard or soft bottom, large fish versus smaller ones,
or rocks and brush on the bottom. For example, a soft, muddy, or weedy
bottom returns a weaker signal which shows a narrow or no gray line. A
hard bottom returns a strong signal that causes a wide gray line.
If you have two targets of equal size, one with gray and the other without,
the target with gray is the stronger echo. This helps distinguish fish from
structure, or the larger fish from a smaller one.
Grayline ®is adjustable. Since it shows the
differencebetweenstrongandweakechoes,
changing the level may require a different
sensitivity setting.
To change the Grayline level, first press the
MENU key until the Grayline menu appears.
Now press the up arrow key to increase the
level,thedownarrowtodecreaseit. Thebar
graph in the Grayline menu box shows the
levelofGraylinenowinuse. Echoesscrolling
onto the screen will also show the effects of
the Grayline change. If you reach the maxi-
mum or minimum level, a tone sounds alert-
ing you to the limits.
The level chosen by the X-45 when it’s first turned on is usually adequate
formost conditions. Experimentwith yourunit to findthe Graylinesetting
that’s best.
FISH ID FEATURE
The Fish ID feature identifies targets that meet certain conditions as fish.
The microcomputer analyses all echoes and eliminates surface clutter,
thermoclines,andotherundesirablesignals. Inmostinstances,remaining
targets are fish. The Fish ID feature displays symbols on the screen in
place of the actual fish echoes. There are four symbol sizes: tiny, small,
medium,andlarge. Theseshowtherelativesizebetweentargets. Inother

13
words,itdisplaysasmallfishsymbolwhenitthinksatargetisasmallfish,
a medium fish symbol on a larger target, etc.
The microcomputer is sophisticated, but it can be fooled. It can't distin-
guish between fish and other suspended objects such as turtles, sub-
merged floats, air bubbles, etc. Individual

Now press the up arrow key. This turns the
feature on. To turn it off, repeat the above

The Fish ID feature can’t be used when the X-45 is in the manual mode.
If you turn the automatic feature off, the Fish ID feature will automatically
