INTRODUCTION
Thank you for purchasing a Lowrance sonar. Your X-25B 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-25B has
powerful features available through easy-to-use menus.
To get started with your Lowrance unit, first read the installation section.
This is where it all begins. Improper installation can cause problems down
the road. After you’ve read the instructions, install the unit, then read the
rest of the manual. The more you know about your unit, the better it will
perform for you. Take this manual for reference when you head for the
water.
NOTICE!
The storage temperature for your unit is from -4 degrees to +167 degrees
Fahrenheit (-20 degrees to +75 degrees Celcius). Extended storage in temperatures 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,
contact the factory customer service department or your local service center.

INSTALLATION - Bracket
You can install the X-25B on the top of a dash or from an overhead with the
supplied bracket. It can also be installed in the dash with an optional IDA3 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 X25B's gimbal bracket to a swivel mount which can be used on the dash or
overhead mounting positions. Installation instructions for the in-dash and
swivel mounting kits are supplied with the adapter kits.
Mount the X-25B in any convenient location, provided there is clearance
when it’s tilted for the best viewing angle. Holes in the bracket’s base allow
wood screw or through bolt mounting. It may be necessary to place a piece
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.
Attach the X-25B to the gimbal bracket using the supplied gimbal knobs
and washers as shown above.
Drill a hole in the dash for the power and transducer cables. The best
location for this hole is immediately under the gimbal bracket. This way, the
bracket covers the hole. The smallest hole the power or transducer cable
connector can pass through is 3/4". However, you can’t pass a power or
transducer connector and another cable through a 3/4" hole. Therefore,
after drilling the hole, pass the transducer connector up through the hole
from under the dash. Then drop the power cable down from the front side
of the dash. After installing the transducer and power cables, slide the
bracket over the hole, then route the transducer and power cables out the
slot in the back of the bracket. Finally, fasten the bracket to the dash.

POWER CONNECTIONS
The X-25B works from a 12 volt DC system only. For the best results, run
the power cable directly to the boat’s battery. Keep the power cable away
from other boat wiring, especially the engine’s wires. This will give the best
isolation from electrical noise. If the supplied cable is not long enough to
reach the battery, splice #18 gauge insulated wire to it. If you do extend the
power cable, make certain to attach the in-line fuse holder supplied with the
X-25B to the battery or power source. This will protect both the unit and the
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.

KEYBOARD BASICS
The unit sounds a tone when you
press any key. This tells you the
unit has accepted a command.
ON/CLEAR
Use this key to turn the unit on. It
also clears menu selections and
the menus from the screen.
OFF
This key turns the unit off.
MENU
The X-25B has many features that are accessed with this key. To see the
first menu, press the MENU key. To see the other menus, press the MENU
key repeatedly.
UP and DOWN ARROWS
Use these keys to adjust virtually every feature and function on the unit.
NOTE: The up arrow key also stops the chart when no menus are
displayed. In other words, anytime you wish to stop the chart, first make
certain no menu is on the screen. Now press the up arrow key. The chart
freezes and the word “STOP” appears at the top of the screen. To start the
chart, press the up arrow key again.
DISPLAY - General
The lights flash for about ten seconds when the X-25B is turned on. Three
menus appear, one after the other. The menus are the lights (LAMP), feetmeter selection (FEET/METER), and contrast adjustment (DARK/LIGHT).
To turn the lights on, press the up arrow key. To switch from feet to meters,
press the down arrow key when the proper menu appears. To adjust the
contrast, wait for the DARK/LIGHT menu to
appear. Now press the up arrow key to
darken the screen, the down arrow to lighten
it. The menus disappear after a few seconds.
If you don’t want to wait, press the ON/
CLEAR key to clear the menus from the
screen.
When the X-25B is first turned on, the display
appears similar to the one at right. The unit is
in the automatic mode. The depth range
displays on the upper left side of the screen.
7
In the example shown at the bottom of the previous page, the range is from
0 to 60 feet and the bottom depth is 34.4 feet.
NOTE: Turning the X-25B off erases all user settings and it returns to the
system defaults. For example, if you turn the lights on, then turn the unit off,
the next time you turn the unit on, the lights will be off, since the default
setting for the lights is off.
MENUS
The X-25B uses menus to guide you through the unit’s functions and
features. The menu key accesses these features, allowing you to
customize the unit to your particular needs and water conditions. All you
have to do to leave one menu and enter another is press the menu key
repeatedly. 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.
Pressing the up arrow key while this menu is on the screen turns the back
lights on.
OPERATION
AUTOMATIC
When the X-25B is first turned on, the automatic feature is enabled. This
feature automatically adjusts the unit’s range and sensitivity according to
water conditions. It always keeps the bottom depth displayed in the lower
portion of the screen.
To turn the automatic feature off, press the
menu key until the AUTO/MAN menu appears. Now press the down arrow key. This
highlights the letters “MAN.” The unit is now
in the manual mode. Wait a few seconds and
the menu will scroll off the screen’s left side.
Pressing the ON/CLEAR key also clears it.
To turn the automatic feature on again, repeat
the above steps, except this time press the up
arrow key.

RANGE
You can’t adjust the range when the X-25B is
in the automatic mode. It is adjustable when
the unit is in the manual mode, however. To
do so, first put the unit in the manual mode.
Now press the ON/CLEAR key to clear the
screen. Then press the menu key until the
“RANGE SEL” menu appears as shown below. The current range shows at the bottom
of the menu. In this case, the range is 60 feet.
Now press the up arrow key to decrease the
range, 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-25B 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-25B depends on the transducer
installation, water and bottom conditions, and other factors.
RANGE - Upper and Lower Limits
The X-25B lets you change the upper and lower range limits when it's in the
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
lower limit to 35 feet, regardless of the bottom
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
the unit is in the manual mode. Next, press the
MENU key until the "UPPER LIMIT" menu
appears. Now press the down arrow key to
increase the upper limit or the up arrow key to
increase it. After you've finished, wait a few
9
21 FOOT UPPER LIMIT
seconds and the menu will scroll off the screen’s left side. Pressing the ON/
CLR key also clears it.
To change the lower limit, again make certain the unit is in the manual
mode. Press the MENU key until the "LOWER LIMIT" menu appears. Now
press the down arrow key to increase the lower limit or the up arrow key
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
enlarging all echoes that appear on the screen.
The unit doesn’t track the bottom in the manual
mode, and the adjustments are slightly different.
Zoom - Automatic Operation
To zoom the display, first press the MENU
key until the RANGE/ZOOM menu appears
as shown at right. Now press the down arrow
key. This switches the unit into the zoom
mode. A new menu immediately appears as
shown at the top of the next page.
