Page 3: Introduction
INTRODUCTION Thank you for purchasing a Lowrance sonar. Your sonar unit is a high quality unit designed for both professional and novice fishermen. All of our sonars 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, all you have to do is press the menu key. -
Page 4: Transducer Installation
If the transducer is not placed in a smooth flow of water, interference will show on the sonar’s display in the form of random lines or dots whenever the boat is moving. -
Page 5: Shoot-Thru-Hull Vs. Transom Mounting
Shoot-thru-hull v.s. Transom Mounting (X-28 and X-38 Only) Typically, shoot-thru-hull installations give excellent high speed opera- tion and good to excellent depth capability. There is no possibility of damage from floating objects. It can't be knocked off when docking or loading on the trailer. - Page 6 2. Slide the transducer between the two ratchets. Temporally slide the bolt though the transducer assembly and hold it against the transom. Looking at the transducer from the side, check to see if it will adjust so that its face is parallel to the ground. If it does, then the “A” position is correct for your hull.

Make certain to leave some slack inthe cable at the transducer as shown above. If possible, route the transducer cable away from other wiring on the boat.

Page 9: Trolling Motor Bracket Installation
Use plastic ties (not included) to attach the transducer cable to the trolling motor shaft. Make certain there is enough slack in the cable for the motor to turn freely. Route the cable to the sonar unit and the transducer is ready for use. FLAT WASHER TMB-S... - Page 10 Next, take the transducer out of the water and place it in the water in the sump of the boat. Observe the sonar signal to see if there is a notice- able decrease in sensitivity. The second bottom signal may disappear and the bottom signal may decrease in intensity.

Do not mix it too fast, as it will cause bubbles to form in the epoxy. (NOTE! Use only the epoxies specified on the inside front cover of this manual! Failure to use one of these epoxies may result in poor sonar performance!) Apply a small amount on the face of the transducer as... -
Page 12: Fish Arches
After the epoxy dries, route the cable to the sonar unit. Fish Arches If you do not get good fish arches on your display, it could be the transducer is not parallel with the ground when the boat is at rest in the water, or at slow trolling speeds. -
Page 13: Power Connections
Failure to use a 3-amp fuse will void your warranty! 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. TO SONAR UNIT TO SPEED/TEMP SENSOR (X-38 and X-48 ONLY) -
Page 14: Bracket Installation
Bracket Installation You can install the sonar unit 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 IDA-3 mounting kit. If you use the supplied bracket, you may be interested in the optional GBSA-1 swivel bracket kit. -
Page 15: Speed/Temperature Sensors
SPEED/TEMPERATURE SENSORS The X-38 and X-48 can use up to three optional temperature sensors which can monitor surface water, live well, air, and virtually any other tempera- ture. You do need to be careful when purchasing the temperature sensors, however. Each temperature sensor has its own "address". The sensors are labeled "Water", "T-2"... -

Page 19: Operation
OPERATION MENUS This unit uses menus to guide you through the unit’s functions and features. The menu key accesses these features, allowing you to cus- tomize 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. -
Page 20: Zoom
After you select the desired range, press the PWR key to clear the display. If you wait a few seconds, it will automatically clear. This unit has the following ranges: 10, 20, 40, 60, 120, 240, 480, and 900 feet. 5, 10, 20, 40, 60, 100, 200, and 300 meters. - Page 21 This means the unit is tracking the bottom in a zoom window, always keeping it on the display. Press the up arrow key to decrease the zoom size, press the down arrow key to increase the zoom size. When the unit is switched into the zoom mode, the letters “ZM”...

Page 22: Upper/Lower Limits
RANGE - Upper and Lower Limits You can change the upper and lower range limits when the unit is 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. -
Page 23: Sensitivity
This sonar unit 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. -
Page 24: Fish Id
® Grayline is adjustable. Since it shows the difference between strong and weak echoes, 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, the down arrow to decrease it. -
Page 25: Fish Track
This feature is automatically enabled when the sonar unit is turned on. To turn it off or on again, press the MENU key repeatedly until the Fish Track menu appears as shown below. -

Page 27: Display Mode
DISPLAY MODE The X-28 has three different screen modes. The X-38 and X-48 both have eight modes. To change modes, press the MENU key until the “DISP MODE” (Display Mode) menu appears. Then press the up or down arrow keys until the desired mode number appears. The modes are as follows:... - Page 28 X-38 and X-48 ONLY CHT 1 (Chart #1) This is the default mode used when the unit is first turned on. It has the following features: 1. Automatic On 2. Fish ID Feature On 3. Digital Depth Display On CHT 2 (Chart #2) Same as Chart-1, but with water tempera- ture added.
- Page 29 X-38 and X-48 ONLY (cont.) CHT 4 (Chart #4) Same as Chart-1, but with water tempera- ture and speed added. CHT 5 (Chart #5) This is the High Speed Scroll mode. It shifts the chart speed into high gear, scrolling ech- oes at a high rate.

This can cause the unit to eliminate weaker signals such as fish or even structure from the display. 3. The water may be deeper than the sonar’s ability to find the bottom. If the sonar can’t find the bottom signal while it’s in the automatic mode,... - Page 35 1. The transducer may be in turbulent water. It must be mounted in a smooth flow of water in order for the sonar to work at all boat speeds. Air bubbles in the water disrupt the sonar signals, interfering with its ability to find the bottom or other targets.
-
Page 36: Electrical Noise
Make certain to use the in-line fuse supplied with the unit when wiring the power cable to the battery! When no noise appears on the sonar unit after all of the above tests, then the noise source is probably cavitation. Many novices or persons with limited experience make hasty sonar installations which function perfectly in shallow water, or when the boat is at rest. - Page 37 LOWRANCE ELECTRONICS FULL ONE-YEAR WARRANTY “We", “our”, or “us” refers to LOWRANCE ELECTRONICS, INC., the manufacturer of this product. “You” or “your” refers to the first person who purchases this product as a consumer item for personal, family, or household use.

Questions and answers
I just bought a used boat which has a Lowrance X 38. All wires seem to be in tact. The previous owner said it worked for him just fine. When I hit the power button, it "beeps" but nothing appears on the screen. It doesn't beep when I press any other keys except the power button. I can't get it to display anything. Any ideas?
If the Lowrance X-38 beeps when the power button is pressed but nothing appears on the screen, possible issues include:
1. Power supply problems – the unit may not be receiving enough power. Check the battery connection and ensure the in-line fuse is properly installed.
2. Display failure – the screen may be malfunctioning even though the unit is receiving power.
3. Improper installation – incorrect wiring or grounding could prevent the display from working.
4. Electrical interference – nearby equipment or poor cable routing may be affecting the unit.
Check power connections, fuse, and cable routing to troubleshoot.
