INTRODUCTION

Thank you for purchasing a Lowrance sonar. Your X-28 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 a menu key. The X-28 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-28 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 X28'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-28 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.

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.

Attach the X-28 to the gimbal bracket using the supplied gimbal knobs and washers as shown above.

POWER CONNECTIONS

The X-28 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-28 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.

PWR/CLEAR

Use this key to turn the unit on and off. It also clears menu selections and the menus from the screen.

MENU FWD/MENU REV

The X-28 has many features that are accessed with these keys. To scroll forward through the menus, press the MENU FWD key repeatedly. To move backwards through the menus, press the MENU REV 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-28 is turned on. Two menus appear, one after the other. The menus are the lights (BACK LIGHT) and feet-meter selection (FEET/METER). To turn the lights on, press the up arrow key while the backlight menu is showing. To switch from feet to meters, press the down arrow key when the proper menu appears. The menus disappear after a few seconds. If you don’t want to wait, press the PWR/CLEAR key to clear the menus from the screen.

When the X-28 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. In the example shown at right, the range is from 0 to 40 feet and the bottom depth is

29.4feet.

NOTE: Turning the X-28 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-28 uses menus to guide you through the unit’s functions and features. The menu keys 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 a menu key repeatedly. If you ever get lost in the menus, simply press the PWR/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 backlight menu is showing. Pressing the up arrow key while this menu shows turns the back lights on.

OPERATION

AUTOMATIC

When the X-28 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 a 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 PWR/ CLEAR key also erases 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-28 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 a menu key until the “RANGE SEL” menu appears as shown at right. 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 PWR/ CLEAR key to clear the display. If you wait a few seconds, it automatically clears.

The X-28 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-28 depends on the transducer installation, water and bottom conditions, and other factors.

RANGE - Upper and Lower Limits

The X-28 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 a 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

21 FOOT UPPER LIMIT

seconds and the menu will scroll off the screen’s left side. Pressing the PWR/CLEAR key also clears it.

To change the lower limit, again make certain the unit is in the manual mode. Press a 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 PWR/CLEAR 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 a 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. Push the MENU FWD key to see the next menu as shown at the top of the next page.
