NOTICE!

The storage temperature for your unit is from -4 degrees to +167 degrees

Fahrenheit (-20 degrees to +75 degrees Celsius). Extended storage in

temperatures higher or lower than specified will damage the liquid crystal

display. This type of damage is not covered by the warranty.

INSTALLATION

TOOLS AND HARDWARE YOU WILL NEED

Screwdriver

Four #10 screws with flat washers or up to 1/4" screws (to attach gimbal

bracket to dash)

Hand-held drill with a 5/32" drill bit

Marine grade caulking compound

TRANSDUCER INSTALLATION:

The HS-3D4 supplied with your X-70A 3D is a 384 kHz, 4 element, high-

speed, transom mount transducer. It can be installed on any outboard or

stern-drive (inboard-outboard) powered boat. The built-in “kick-up” bracket

helps prevent damage if the transducer strikes an object while the boat is

moving. If the transducer does “kick-up”, it can be pushed back in place

without tools.

Read this section carefully before attempting the installation. Determine

the best mounting location for your boat. Remember, the transducer loca-

tion is the most critical part of a sonar installation. If it isn’t done properly,

the sonar can’t perform to it’s designed potential.

Transducer Location

1. The transducer must be placed in a location that has a smooth flow of

water at all times. If the transducer is not placed in a smooth flow of

water, interference will show on the sonar’s display in the form of ran-

dom lines or dots whenever the boat is moving and can completely

mask the sonar image at high speed.

2. The transducer should be installed with its face pointing straight down,

if possible.

3. Make certain the chosen location doesn’t interfere with the boat’s trailer.

Also, don’t mount it closer than about one foot from the engine’s lower

unit. This will prevent cavitation interference with the propeller. Typi-

cally, the transducer should be mounted as far down on the transom

as possible. This increases the chance that it will remain in the water

at high speed or sharp turns, and reduces the possibility of air bubble

interference (cavitation).

4. Don’t mount the transducer directly behind strakes or ribs on the bot-

tom of the hull. Typically, a good location on aluminum boats is be-

tween the ribs closest to the engine. The port (left) side of the transom

is preferred for mounting the transducer, however, if this is not pos-

sible, the starboard (right) side can be used, usually with good results.

Transducer Assembly and Mounting

The best way to install this transducer is to loosely assemble all of the

parts first, place the transducer’s bracket against the transom and see if

you can move the transducer so that it’s parallel with the ground.

1. Press the two small plastic ratchets into the sides of the metal bracket

as shown below. Notice there are letters molded into each ratchet.

Place each ratchet into the bracket with the letter “A” aligned with the

dot stamped into the metal bracket. This position sets the transducer’s

coarse angle adjustment for a fourteen (14) degree transom. Most

outboard and stern-drive transoms have a fourteen degree angle.

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. If the transducer’s face isn’t parallel with the ground,

remove the transducer and ratchets from the bracket. Place the ratch-

ets into the holes in the bracket with the letter “B” aligned with the dot

stamped in the bracket. Reassemble the transducer and bracket and

place them against the transom. Again, check to see if you can move

the transducer so it’s parallel with the ground. If it does, then go to step

3. If it doesn’t, repeat step 2, but use a different letter until you can

place the transducer on the transom correctly.

3. Once you determine the

correct position for the

ratchets, assemble the

transducer as shown at

left. Do not tighten the lock

nut at this time.

4. Hold the transducer and bracket assembly against the transom. The

transducer should be roughly parallel to the ground. The bottom of the

transducer bracket should be in line with the bottom of the hull.

Don't

let the bracket extend below the hull!

Mark the center of the slots for

the mounting holes. Drill two 5/32" holes in the marked locations for

the #10 screws supplied with the transducer.

5. Attach the transducer to the transom. Slide the transducer up or down

until it’s aligned properly on the transom as shown above. Tighten the

bracket’s mounting screws. Adjust the transducer so that it’s parallel to

the ground and tighten the lock nut until it touches the flat washer, then

add 1/4 turn.

Don’t over tighten the lock nut!

If you do, the transducer

won’t “kick-up” if it strikes an object in the water.

TRANSOM

SIDE VIEW

6. Route the transducer cable to the sonar unit. If possible, route the

transducer cable away from other wiring on the boat. Electrical noise

from the engine’s wiring, bilge pumps, VHF radio wires and cables,

and aerators can be picked up by the sonar. Use caution when routing

the transducer cable around these wires.

IMPORTANT!

Clamp the transducer cable to the transom close to the transducer. This

can prevent the transducer from entering the boat if it is knocked off at

high speed.

7. Make a test run to determine the results. If the bottom is lost at high

speed, or if noise appears on the display, try sliding the transducer

bracket down. This puts the transducer deeper into the water, hope-

fully below the turbulence causing the noise. Do not allow the trans-

ducer bracket to go below the bottom of the hull!

SONAR UNIT MOUNTING

Install the X-70A 3D in any convenient location, provided there is clear-

ance behind the unit when it is tilted for the best viewing angle. Holes in

the bracket base allow wood screw or through-bolt mounting. Make cer-

tain there is enough room behind the unit to attach the power and trans-

ducer cables.

Using the bracket as a template, mark the dash for the mounting holes,

then make a mark in the center of the bracket location for the cable hole.

If you want the smallest possible hole for the power and transducer cables

in the dash, install the transducer first, then route the cable to the desired

location. The smallest hole that will pass one power or transducer plug is

5/8". After the hole is drilled, pass the transducer connector up through

the hole first, then pass the power cable down through it.

After routing the cables, fill the hole with a good marine sealing com-

pound. Place the bracket over the hole and route the cables through the

slot in the back of the bracket. Break out one of the other slots for the

transducer cable. Screw the bracket to the dash.

SLOT BREAK OUT SLOT

POWER CONNECTIONS

The X-70A 3D works from a twelve-volt battery system. For the best re-

sults, attach the power cable directly to the battery. You can attach the

power cable to an accessory or power buss, however you may have prob-

lems with electrical interference. Therefore, it’s safer to go ahead and

attach the power cable directly to the battery. If the cable isn’t long enough

to reach the battery, splice #18 gauge wire onto it. The power cable has

two wires, which are red and black. Red is the positive lead, black is nega-

tive or ground. Make certain to attach the in-line fuse holder to the red

lead as close to the power source as possible. For example, if you have to

extend the power cable to the battery or power buss, attach one end of

the fuse holder directly to the battery or power buss. This will protect both

the unit and the power cable in the event a short occurs.

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.

If you’ve purchased the optional ST-T speed/temperature sensor, install it

according to the instructions included with the sensor. Route its cable to

the X-70A 3D’s power cable and plug it into the connector marked “SPEED/

TEMP CABLE”.

DISPLAY - General

When the X-70A 3D is first turned on, the display looks similar to the one

below. The 3D screen scrolls from right to left, with the scale on the right

side of the screen. The current depth beneath the transducer shows in

the upper right corner of the display. A fish symbol to the left of the depth

shows that the Fish ID feature is on. The word “AUTO” signifies that the

automatic function is on, keeping the bottom on the display at all times. If

the computer identifies targets as fish, one of four fish symbols appear on

the screen, depending on the size of the target. Numbers above the fish

symbol tell you the depth of the target. This feature is called “FishTrack”.

The lights are on for a few seconds when the X-70A 3D is turned on.

Menus appear at the same time. To leave the lights on, press the ON key.

This key controls the back lights. If you don’t want the lights on, wait a few

seconds and they will automatically turn themselves off. The menus will

also disappear after a few seconds, or you can press the CLEAR key to

erase them.

The Metric and Display menu labels work the same way. Press the key

adjacent to the Metric label to change the depth from feet to meters. This

also changes the temperature display to degrees Celsius, speed to knots,

and log to kilometers.

The Display menu on the screen's right side lets you adjust the display’s

for the best contrast. Press the left arrow key to decrease the contrast,

right arrow key to increase it.

The X-70A 3D automatically detects the speed/temperature sensor. If the

sensor is attached to the unit, speed, temperature, and distance log auto-

matically appear on the display. Distance markers also appear on the

screen, showing the distance behind the boat. If the speed/temperature

sensor is not plugged into the X-70A 3D, then none of these will show.

MODES OF OPERATION

The X-70A 3D shows a sonar picture of the underwater world in 3D, 2D,

Bottom Depth View, and FasTrack™ modes. The 2D and Bottom Depth

Views can use either the 384

or 192 kHz transducer (if the

optional 192 kHz transducer is

attached). The 3D mode is al-

ways 384 kHz. To switch be-

tween the different modes, first

press the WINDOWS key.

Press a key on the left side of

the screen to choose the de-

sired mode. Press the CLR

key to exit this menu.

In the 3D mode shown at right,

the bottom is represented by a “wire-frame” model. Only the bottom and

fish symbols show in this mode. Structure, weeds, thermoclines, etc. will

not show.

The X-70A 3D uses a 384 kHz transducer with four elements. The digital

depth display shows the bottom depth from the middle transducer ele-

ments. If it loses the signal from any element, a box with the word “LOST”

appears over the corresponding area on the display. This means the unit

cannot receive an echo from that element. This could be due to a large

drop-off, noise or other natural phenomenon.

The 2D mode looks like a conventional sonar display as shown below.

The bottom echo scrolls from right to left. The range displays on the right

side of the screen. The digital

bottom depth shows in the

upper left corner. When the X-

70A 3D is put into the 2D 384

kHz mode, the two center

transducer elements are in

use. The two outer elements

are turned off. You can select

the elements from a menu dis-

cussed in a later section. The

2D 192 kHz transducer has

only one element.

All 2D modes show the bottom signal, structure, thermoclines, fish (both

with and without the Fish ID feature), baitfish schools, and more. The 3D

view shows a 3D representation of the bottom, with Fish ID symbols only.

The 2D mode shows more information, the 3D mode makes it easier to

visualize the bottom contour.

The Bottom Depth View as

shown at right displays the

depth at the top of the display

in large digits. The graph

scrolls at high speed. Note that

this graph only shows the bot-

tom signal. No structure, fish

signals, or other echoes show

on this display. This feature is

available using either fre-

quency transducer. (384 Bot-

tom or 192 Bottom)

The 3D FasTrak screen con-

verts echoes from all four

transducer elements into short

horizontal lines. Typically, the

thicker the bar, the stronger

the echo. This screen is up-

dated rapidly, giving you

flasher-like performance. You

can view echoes from any or

all elements on this screen.

DIGITAL BOX

A box containing the digital

displays appears in the upper

left corner of the display when

a 2D display is enabled. You

can switch the size of the dis-

play from normal to large by

pressing the FULL CHART

key or by pressing the up or

down arrow keys on the selec-

tion menu.

OPERATION

The Automatic and Sensitivity features used on the X-70A 3D are the

same for all modes of operation. This section will explain these features.

For information on features specific to different modes, see the 2D or 3D

operation sections.

AUTOMATIC

The X-70A 3D adjusts the sen-

sitivity and range to keep a

detailed bottom signal on the

display when the automatic

feature is on. This is enabled

when the unit is first turned on.

You can turn this feature off to

gain greater control over the

adjustments and features of

this unit.

To turn automatic off, press the AUTO key. A screen similar to the one

above appears. Now press the AUTO key again. This moves the check

mark from the “AUTO” box to “MAN”. Press the CLR (clear) key to erase

the menu. To switch back to manual, repeat the above steps, but move the

check mark to the “AUTO” box using the AUTO key.

SENSITIVITY

The sensitivity control adjusts

the receiver’s ability to show

echoes. If it’s adjusted prop-

erly, the sonar unit shows not

only the bottom, but targets

(such as fish) with little or no

noise. If the sensitivity is

turned too low, no fish signals

will show, and you will lose the

bottom signal in fairly shallow

water.

When the X-70A 3D is in the automatic mode, the computer inside ad-

justs the sensitivity for the best setting. You can override this setting, add-

ing or subtracting the amount of sensitivity the computer uses. You can

also take complete control of the sensitivity level when the unit is in the

manual mode.

To adjust the sensitivity, press the SENS key. A menu appears on the

right side of the screen as shown on the previous page. Press the right

arrow key to increase it, the left arrow key to decrease it. When you have

it changed to the desired level, press the CLR key to erase the menu or

wait a few seconds for it to automatically clear.

3D OPERATION

When the X-70A 3D is in the 3D mode, the Fish ID feature is always on

(unless you turn it off). FishTrack (the depth numbers above the fish sym-

bols) shows you the depth of the fish symbol and can be turned off, if

desired. See the FishTrack section in this manual for more information.

3D RANGE

The range is set by the unit as long as it’s in the auto mode. However, you

can adjust the range slightly when automatic is on. The unit won’t let you

move the bottom off the screen, and it will correct the range once the

bottom begins to go off the screen. When the unit is in the manual mode,

you can set the range to any that’s available.

To change the range on the X-

70A 3D, first press the RANGE

key. A screen similar to the one

at right appears. Simply press

the down arrow key to in-

crease the range or the up ar-

row key to decrease it. When

the desired range is chosen,

wait a few seconds and the

menu will automatically disap-

pear from the screen or press

the CLR key to erase it.

The X-70A 3D uses the following ranges: 0 - 5, 10, 20, 40, 60, 80, 100,

150, 200, 300, 400, 500, 700, and 900 feet.

3D ZOOM

The zoom feature enlarges all echoes on the screen, making them easier

to see. This feature works in automatic or the manual mode. (Note: If the

unit is in the 3D automatic mode and the zoom feature is turned on, the

unit will not change the range to a shallower setting. If the bottom signal

goes shallower than the zoom range, the X-70A 3D will simply show a flat

bottom signal at the shallowest range shown on the display. For example,

if you have a zoom range from 45 to 60 feet, and the bottom rises to 30

feet (shown by the digital depth

display), the unit will show a

flat bottom at 45 feet.)

To use the zoom feature, first

press the ZOOM key, then

press the key next to the zoom

menu that appears in the lower

left corner of the display as

shown at right. This switches

the unit to the 2X zoom mode.

This enlarges all echoes on

the screen to twice their nor-

mal size. If you press the key again while the menu is showing, the unit

will switch to the 4X zoom mode. This enlarges all echoes four times their

normal size.

Turn the zoom feature off by repeatedly pressing the key next to the zoom

menu until the check mark is on the OFF box. Wait a few seconds for the

menu to automatically disappear from the screen or press the CLR key to

erase it.

3D VARIVIEW™

When the X-70A 3D is first turned on, the 3D screen scrolls from right to

left as shown above. This view shows you the bottom contour as if your

boat is travelling from the left side of the screen to the right side. The

upper right corner of the screen is the right (starboard) side of your boat’s

transom. There are occasions when you may wish to change the viewing

angle of the bottom. For example, if you’re travelling parallel to a drop-off,

the far side of the drop-off may not be visible, due to the higher ground

obstructing the drop-off. By rotating the 3D view, the opposite side of the

drop-off can be seen.

To change the 3D view, first

press the WINDOWS key. The

screen shown at right appears.

There are four views available.

Press the arrow keys to rotate

the 3D view. When you’ve ro-

tated the display to the desired

view, press the CLR key to re-

turn to the 3D screen.

2D OPERATION

2D Transducer Element Se-

lection

This view shows all echoes in the traditional sonar graph display. You can

view echoes from any two 384 kHz transducer elements, or the 192 kHz

transducer. (Note: 192 kHz operation requires an optional 192 kHz trans-

ducer.) To select the transducer element and place the X-70A 3D into the

2D mode, press the WINDOWS key. Next, press the key next to the "2D

384 kHz" label or the "2D 192 kHz" label. The screen shown at right ap-

pears.

If you want to use only the cen-

ter two transducer elements,

simply press the CLR key to

switch to the 2D chart display.

As shown in the picture at

right, the shaded area beneath

the boat shows which trans-

ducer elements are in use.

When this unit is first turned

on, only the two center ele-

ments are in use for the 2D mode. To change to other elements, press the

left or right arrow keys. As you press the keys, the shaded area on the

screen moves also, showing you which transducer elements are in use.

Once you’ve selected the desired transducer elements, simply press the

CLR key to switch to the 2D chart display.

2D RANGE

The range is set by the unit as long as it’s in the auto mode. However, you

can adjust the range slightly when automatic is on. The unit won’t let you

move the bottom off the screen, and it will correct the range once the

bottom begins to go off the screen. When the unit is in the manual mode,

you can set the range to any

that’s available.

Automatic mode

To change the range, first

press the RANGE key. A

screen similar to the one at

right appears. Now press the

down arrow key to increase

the range or the up arrow key

to decrease it. When the de-

sired range is chosen, wait a

few seconds and the menu will automatically disappear from the screen

or press the CLR key to erase it.

Manual mode

When the X-70A 3D is in the manual mode, any range can be selected.

The unit will leave the range setting you choose, but it won't keep the

bottom on the display. For ex-

ample, if the range is 0 - 60

feet, and the bottom signal

goes from 55 to 70 feet, once

the bottom goes deeper than

60 feet, it won't show on the

display.

To change the range, first

press the RANGE key. A

screen similar to the one at

right appears. You can simply

use the up or down arrow keys

to select the range, or you can

use the upper and lower limit menus.

The X-70A 3D uses the following ranges: 0 - 5, 10, 20, 40, 60, 80, 100,

150, 200, 300, 400, 500, 700, and 900 feet.

Upper and Lower Limits

The X-70A 3D gives you added versatility with the upper and lower limits

menu. The upper limit is the depth shown at the top of the screen, which is

normally zero. The lower limit is the depth shown at the bottom of the

screen which is normally a range such as 60 feet. By manually entering

the upper and lower limits, you can select any segment of the water using

increments as little as one foot! Changing the upper and lower limits in

this manner actually gives you a zoom in the manual mode that is much

more versatile than the standard zoom.

To change the upper limit, first make certain the unit is in the manual

mode, then press the RANGE key. Now press the key next to the "Set

Upper Limit" label. A screen similar to the one at the top of the next page

appears.

Now enter the upper limit, in any number as long as it's 10 feet or more

less than the lower limit. For example, if the range is 0 -60 feet, you can

use any number between 0 and 50 feet as an upper limit. After entering

the upper limit, press the ENT key. This returns the unit to the range menus

and your new upper limit will

be at the top of the screen.

To change the lower limit, use

the same steps as above, but

press the key next to the "Set

Lower Limit" menu.

Press the CLR key to erase

these menus or wait a few sec-

onds and they will automati-

cally disappear.

2D ZOOM - Automatic mode

The zoom feature enlarges all echoes on the screen, making them easier

to see. This feature works in automatic or the manual mode. The X-70A

3D can show a full 2D zoom screen or a split-screen with the right side

normal and the left side enlarged.

To use the zoom feature, first

press the ZOOM key. A screen

similar to the one at right ap-

pears. Now press the key next

to the "OFF 2X 4X" menu.

This switches the unit to the

2X zoom mode which en-

larges all echoes on the

screen to twice their normal

size. If you press the key again

while the menu is showing, the

unit will switch to the 4X zoom

mode. This enlarges all ech-

oes four times their normal size.

To use the split-screen zoom feature, press the key adjacent to the “FULL

SPLIT” label. This instantly divides the screen in half. The left half of the

screen is zoomed, the right side is a full-scale, top-to-bottom view of the

same area. The echoes that scroll across the screen are the same on

both sides of the screen, but they are enlarged and show in greater detail

on the left side. To switch back to full screen, press the ZOOM key, then

press the key next to the “FULL SPLIT” label.

Turn the zoom feature off by repeatedly pressing the ZOOM key until the

check mark is on the OFF box. Wait a few seconds for the menu to auto-

matically disappear from the screen or press the CLR key to erase it.

2D ZOOM - Manual Mode

The zoom feature works the same in manual as it does in automatic with

two exceptions. One, since the unit is in manual, the unit won’t change the

range to keep the bottom signal on the display. Two, you can adjust the

zoom “window” to any desired depth.

To zoom the screen in the manual mode, first press the ZOOM key. A

screen similar to the one on the previous page appears. You’ll notice a

new label on the screen: “ADJUST”. Press the key next to that label. A

screen similar to the one at right appears.

The unit is now in the split-

screen zoom mode. A zoom

bar is on the far right side of

the screen. Use the up and

down arrow keys to move this

bar up and down the right side

of the screen. Everything be-

tween the top and bottom of

this bar shows on the left side

of the screen in either 2X or

4X scale. When you have the

zoom bar in the desired loca-

tion, press the CLR key to erase it or wait a few seconds and it will auto-

matically disappear.

You can have the zoom bar stay on the screen continuously, by using the

zoom bar menu. See the 2D Options in the MENUS section for more

information.

BOTTOM DEPTH VIEW

To use the Bottom Depth View, first press the WINDOWS key. Now press

the key next to the "384 Bottom" or "192 Bottom", depending on the trans-

ducer you wish to use or have installed. Finally, press the CLR key. A

screen similar to the one at the top of the next page appears.

This view shows the water depth in large digital numbers at the top left

corner of the screen. If an optional speed/temperature sensor is installed,

the unit can also show boat speed, distance travelled (log), surface water

temperature, and a surface water temperature graph in this area.

Next to the digital display box is the chart record. This shows depth infor-

mation only. No fish, structure,

or any echoes other than the

bottom signal appear on this

screen. You can adjust the

range, however this is the only

adjustment you can make on

this screen. The X-70A 3D au-

tomatically sets the sensitivity

level.

FASTRAK™

The FasTrak™ view converts

all echoes to short horizontal

lines. Typically, the thicker the line, the stronger the signal. This view gives

you an immediate, “real-time” screen display. This high-speed display rep-

licates flasher performance. You can adjust sensitivity, range, and turn

automatic on or off in this

mode. Zoom is not available.

To use the Fastrak™ mode,

first press the WINDOWS key.

Now press the key next to the

"3D Fastrak" menu. A screen

similar to the one at right ap-

pears. When the X-70A 3D is

first turned on, only the cen-

ter two transducer elements

are in use. By pressing the left

or right arrow keys other ele-

ments can be selected. When you have the desired elements selected,

press the key next to the "Exit" menu. A screen similar to the one below

appears.

A representation of each of the

four transducer elements

shows on this screen. The digi-

tal displays are on the screen's

left side. Range scale numbers

are shown on the right side of

the transducer cone.

Echoes from each element

show in it’s respective cone.

Fish and other suspended tar-

gets appear as short, thin lines; usually for very short periods of time. The

bottom echo usually looks like a slice taken from the 2D screen. Surface

clutter appears at the top of the screen, near the picture of the boat.

Using the Fastrak screen combines the “instant read” of a flasher with the

versatility and convenience of a liquid crystal graph.

MENUS

The X-70A 3D uses menus

extensively to guide you

through the unit’s features. The

MENU key accesses most of

the these features, letting you

customize the unit to your par-

ticular water conditions. You

can exit from any menu by

pressing the CLR key.

MENU - Page 1

CHART STOP

The X-70A 3D gives you the

ability to stop the chart for study. You can stop the chart no matter which

mode the unit is in - 3D, 2D, Bottom View, or FasTrack. (Note: Stopping

the chart doesn't stop the digital sonar. The digital depth display will con-

tinue to operate.)

To stop the chart or start it, press the MENU key, then press the key next

to the "Chart Stop Run" menu. Finally, press the key next to the "Exit"

label. The unit returns to the last used sonar display.

ALARMS

The X-70A 3D has three different alarms. The first is the Fish Alarm. It

sounds when the Fish I.D. feature places a fish symbol on the screen.

(This alarm only works in the 2D and 3D modes.) Another alarm is the

Zone Alarm which consists of a bar on the right side of the screen. Any

echo that appears inside of this bar triggers the alarm. The last alarm is

called the Depth Alarm. It actually consists of two alarms - shallow and

deep. Only the bottom signal can trigger these alarms. They are useful as

an anchor watch, a shallow water alert, or for navigation.

To adjust an alarm, first press the MENU key, then press the key next to

the "Alarms" label. The screen shown at the top of the next page appears.

Follow the instructions to set each alarm.

DEPTH ALARMS

The depth alarms sound a

tone when the bottom signal

goes shallower than the shal-

low alarm’s setting or deeper

than the deep alarm’s setting.

For example, if you set the

shallow alarm to ten feet, the

alarm will sound a tone if the

bottom signal is less than ten

feet. It will continue to sound

until you mute it or the bottom

goes deeper than 10 feet. The

deep alarm works just oppo-

site. It sounds a warning tone

if the bottom depth goes

deeper than the alarm’s set-

ting. Both depth alarms work

only off the digital bottom

depth signals. No other tar-

gets will trip these alarms.

Both can be used at the same

time.

To set the depth alarms,

press the key adjacent to the

alarm you wish to set. In this

example, we will set and turn

on the shallow alarm. When

the X-70A 3D is turned on, the

shallow alarm is set to zero.

Pressing the key next to the

“Shal Alarm” menu moves the

check mark to the "SET" box.

This brings up the adjustment

menu, as shown above. Using

the numbered keys, enter the

depth for the shallow alarm. In

this example, we used 10 feet.

Press the key next to the “Ac-

cept” label. The screen returns to the alarm menu. The number you en-

tered shows on the shallow alarm’s menu. You’ll also notice that the check

mark in the shallow alarm’s menu has moved to the “ON” box. Setting an

alarm also turns it on. Press the CLR key to return to the sonar display.

Using our example, if the bottom signal goes lower than 10 feet, the shal-

low alarm sounds a tone.

To turn the shallow alarm off, press the MENU key, then press the key

next to the "Alarms" label. Now press the key next to the "Shal Alarm"

menu until the check mark moves to the “OFF” box. Press the CLR key to

return to the sonar display.

Remember, the shallow and deep alarms adjust exactly the same. The

only difference is the shallow alarm sounds when the bottom signal goes

shallower than the shallow alarm’s setting. The deep alarm sounds when

the bottom signal goes deeper than the deep alarm’s setting.

ZONE ALARM

The zone alarm only works on

the 2D chart or 2D FasTrak

view. Any echo that passes

inside the zone alarm’s bar

sets it off. To adjust the zone

alarm, first press the MENU

key, then press the key next

to the "Alarms" label. Now

press the key next to the

"Zone Alarm" label. A new

menu appears at the bottom

of the screen. Finally, press

the key next to the "Accept"

label. The screen shown above appears.

The zone alarm’s bar appears on the right side of the screen. Adjustment

menus show in the middle of the screen. Press the up or down arrow keys

to move the

bottom

of the zone alarm bar up or down. To adjust the top of

the zone alarm bar, first press the key adjacent to the "Adjust Upper"

label. After setting the zone alarm bar, press the CLR key to erase the

menus and bar or wait a few seconds and they will automatically clear.

(You can turn the zone alarm’s bar on continuously. See the 2D View

Options section for more information.)

Setting the zone alarm automatically turns it on. To turn it off, press the

ALARM key, then press the key next to the zone alarm’s menu. This moves

the check mark from "ON" to “OFF”. Press the CLR key to exit the alarm

menu.

FISH ALARM

The fish alarm sounds a distinctive tone when the X-70A 3D places a fish

symbol on the display. A different tone sounds for each of the four fish

symbol sizes.

To turn the fish alarm on, first press the MENU key, then press the key

next to the "Alarms" label. Finally, press the key next to the "Fish Alarm"

label. This moves the check

mark from the “OFF” box to the

“ON” box. Press the CLR key

to return to the sonar display.

To turn the fish alarm off, re-

peat the above steps.

(Note: The automatic and Fish

ID features must be on in or-

der to use the fish alarm. If you

turn the fish alarm on and

these other features are off,

the unit will automatically turn

them on.)

ALARM MUTE

Whenever a depth alarm sounds, a message appears on the display tell-

ing you which alarm is sounding. A “Silence Alarm” menu appears on the

display at the same time. Press the key next to this menu to mute or turn

the alarm’s sound off. This doesn’t turn the alarm off, only silences the

tone until the alarm is triggered again.

FISH I.D.

The Fish I.D. feature identifies targets that meet certain conditions as fish.

The microcomputer analyses all echoes and eliminates surface clutter,

thermoclines, and other signals that are undesirable. In most instances,

remaining targets are fish. The Fish I.D. feature displays symbols on the

screen in place of the actual fish echoes. There are four fish symbol sizes:

tiny, small, medium, and large. These are used to designate the relative

size between targets. In other words, it displays a small fish symbol when

it thinks a target is a small fish, 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 trotlines, turtles,

submerged floats, air bubbles, etc. Individual tree limbs extending out-

wards from a group of limbs is the hardest object for the Fish I.D. feature

to distinguish from fish. You may see Fish I.D. symbols on the screen

when actually, there are no fish. Practice with the unit in both the Fish I.D.

mode and without to become more familiar with the Fish I.D. feature.

When the X-70A 3D is turned on, the Fish I.D. feature is automatically

turned on, also. To turn the

Fish I.D. feature off, press the

MENU key, then press the key

adjacent to the “Fish ID” label.

This moves the check mark

from the “ON” to the “OFF”

box. The unit returns to the

sonar display with Fish ID off.

To turn the Fish I.D. feature on

again, repeat the above steps.

The menu immediately disap-

pears and the sonar screen

returns. In the 2D mode, ech-

oes will continue to scroll

across the screen, however, the surface clutter at the top will no longer be

displayed. Any targets the microcomputer determines are fish will be dis-

played as fish symbols.

Remember, the Fish I.D. feature can’t be used when the X-70A 3D is in

the manual mode. If you turn the Fish I.D. feature on when the unit is in

manual, the microcomputer will turn the automatic feature on. If you turn

automatic off when the Fish I.D. feature is on, the Fish I.D. feature will be

turned off also.

DISPLAY CONTRAST

The unit’s display contrast is adjustable to suit different lighting condi-

tions. To adjust it, first press the MENU key. The first menu page appears.

Now press the key next to the

“Display Contrast” label. A

screen similar to the one at

right appears. Now press left

arrow key to decrease the

contrast. Press the right arrow

key to increase it. The percent-

age of contrast in use changes

as the arrow keys are pressed.

The bar chart also gives a

graphical indication of the con-

trast level. You can see the

FISH ID ON

change on the screen as you press the keys. After you’ve made the ad-

justment, press the CLEAR key to erase the menu.

2D VIEW OPTIONS

The 2D view has several ad-

justments that (with some ex-

ceptions noted below) affect

the 2D view screen only. To

use these options, first press

the MENU key, then press the

key next to the “2D VIEW OP-

TIONS” label. A menu similar

to the one at right appears.

DIGITAL BOX OPTIONS

The X-70A 3D can display the depth, speed, surface water temperature,

and distance log on all sonar screens, including the 2D, 3D, Bottom Depth

View, and FasTrak. (Speed, temperature, and log displays require an op-

tional speed/temperature sensor.) When the X-70A 3D is first turned on,

only the depth is displayed if the sensor is not connected. You can turn

each digital display on as desired or turn all of them off, as desired.

To select the digital displays menu, first press the MENU key. Next, press

the key adjacent to the “2D View Options” label. Finally, press the key next

to the “Digital Box Options” menu. The screen shown below appears.

Now press the key adjacent to the desired display. For example, to turn

the temperature display on, press the key adjacent to the “TEMPERA-

TURE” label. Once you do this, the digital display in the corner of the

screen will show the temperature in addition to the depth. You can turn

each display on or off, individu-

ally.

If you wish to turn all of the

digital displays off, simply

press the key next to the

“DIGITAL BOX” label. Press

the CLEAR key to exit from

this menu.

DIGITAL SONAR

When the X-70A 3D’s 2D

screen is turned on for the first

time, the digital depth display

is located at the top left cor-

ner of the screen. This display

comes from a separate digital

sonar built into the unit. It dis-

plays only the bottom depth. If

it loses the bottom, the last

known depth will flash on the

display. When the digital finds

the bottom, it will automatically

display the bottom depth

again.

The digital sonar can be turned off, however this also turns all automatic

features off also, such as auto sensitivity, auto ranging, and the Fish I.D.

feature.

To turn the digital sonar off, first press the MENU key. Next, press the key

adjacent to the “2D View Options” label. Finally, press the key next to the

“Digital Sonar” menu. To turn it back on, repeat the same steps.

2D FASTRAK BAR

This feature converts all echoes to short horizontal lines on the 2D display’s

far right side. The graph continues to operate normally. FasTrak™ gives

you a rapid update of conditions directly under the boat. This makes it

useful for ice fishing, or when you’re fishing at anchor. Since the unit is not

moving, fish signals are long, drawn out lines on a normal chart display.

FasTrak™ converts the graph to a vertical bar graph that, with practice,

makes a useful addition to fishing at a stationary location.

To turn FasTrak™ on, first

press the MENU key. Next,

press the key adjacent to the

“2D View Options” label. Fi-

nally, press the key next to the

“FasTrak Bar” menu. To turn it

back on, repeat the same

steps.

ZOOM BAR

When the unit is in the 2D split-

screen zoom mode, the zoom

bar doesn’t normally show on

the screen. The zoom bar

shows the section of water on

the right side of the screen that

the zoom feature displays on

the left side. To turn the zoom

bar on continuously, first press

the MENU key. Next, press the

key adjacent to the “2D View

the key next to the “Zoom Bar”

menu. Press the CLR key to return to the sonar display. The zoom bar will

show on the far right side of the display when it’s in the 2D split-screen

zoom mode. To turn it off, repeat the same steps.

DISPLAY ZONE ALARM

BAR

When the zone alarm is on, the

zone bar doesn’t normally

show on the screen. To turn

the zone bar on continuously,

first press the MENU key. Next,

press the key adjacent to the

“2D View Options” label. Fi-

nally, press the key next to the

“Zone Bar” menu. Press the

CLR key to return to the sonar

display. The zoom bar will

show on the far right side of the display when it’s in the 2D mode. To turn

it off, repeat the same steps.

CHART CURSOR

The X-70A 3D has a chart cur-

sor that allows you to pinpoint

a target’s depth. The cursor is

simply a horizontal line that

extends across the display

from left to right. A depth box

at the end of the line on the

right side shows the line’s

depth. In the example at right,

the cursor (line) is at 16.4 feet.

To display the chart cursor, press the MENU key. Next, press the key

adjacent to the “2D View Options” label. Finally, press the key next to the

“Chart Cursor” menu. Press the CLR key to return to the sonar display.

Use the up or down arrow keys to move the cursor up or down to the

desired depth.

To turn the chart cursor off, repeat the above steps. The unit returns to the

sonar screen without the chart cursor.

MENU - PAGE 2

GRAYLINE®

GRAYLINE® lets you distin-

guish between strong and

weak echoes. It “paints” gray

on targets that are stronger

than a preset value. This al-

lows you to tell the difference

between a hard and soft bot-

tom. For example, a soft,

muddy or weedy bottom re-

turns 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. Since GRAYLINE® shows the difference be-

tween strong and weak signals, adjusting the sensitivity may require a

GRAYLINE® ON GRAYLINE® OFF

different GRAYLINE® level,

also. The level chosen by the

X-70A 3D is usually adequate

for most conditions. Experi-

ment with your unit to find the

GRAYLINE® setting that’s best

for you.

To adjust GRAYLINE®, press

the MENU key twice, then

press the key adjacent to the

“Adjust Grayline” label. A

screen similar to the one at

right appears. Now press the left arrow key to decrease the gray level.

Press the right arrow key to increase it. The percentage of GRAYLINE® in

use changes as the arrow keys are pressed. The bar chart also gives a

graphical indication of the GRAYLINE® level. You can see the change on

the screen (both on the menu and on the chart record) as you press the

keys. After you’ve made the adjustment, press the CLEAR key to erase

the menu.

CHART SPEED

The rate echoes scroll across

the screen is called the chart

speed. It’s adjustable by first

pressing the MENU key twice,

then pressing the key adjacent

to the “Adjust Chart Speed” la-

bel. The chart speed menu

appears on the screen's right

side. Increase the chart speed

by pressing the right arrow key

or decrease it by pressing the

left arrow key. The percentage

of chart speed in use changes as the arrow keys are pressed. The bar

chart also gives a graphical indication of the chart speed. You can see the

change on the screen (both on the menu and on the chart record) as you

press the keys. After you’ve made the adjustment, press the CLR key to

erase the menu.

The percentage of volume in use changes as the arrow keys are pressed.

The bar chart also gives a graphical indication of the level. After you’ve

made the adjustment, press the CLR key to erase the menu.

UNITS OF MEASURE

When the optional speed/temperature sensor is connected, the X-70A

3D can display the water depth in feet, fathoms, or meters, surface water

temperature in degrees Fahrenheit or Celsius, speed in statute miles per

hour, kilometers per hour, or knots, distance (log) in miles, kilometers, or

nautical miles, and the 3D distance markers in feet or meters.

To change the units of measure, first press the menu key two times. Next,

press the key adjacent to the “Units of Measure” label. The screen shown

below appears. The check

mark in the box on each line

shows the unit of measure

currently in use. In the screen

sure are in feet for the depth,

temperature in degrees Fahr-

enheit, speed is in statute

miles per hour, and log is in

statute miles.

Press the key adjacent to the

unit that you wish to change.

For example, press the key next to the "Depth" label two times to switch

from feet to meters. This moves the check mark two times from the “Ft” to

the “M”.

After setting the units of measure, press the CLR key.

MENU - PAGE 3

SURFACE CLARITY

The markings extending

downward from the zero line

on the 2D chart when the

manual mode is on are called

“surface clutter.” These mark-

ings are caused by wave ac-

tion, boat wakes, temperature

inversion, and other natural

causes.

The Surface Clarity Control (SCC) reduces or eliminates surface clutter

signals from the display. SCC varies the sensitivity of the receiver, de-

creasing it near the surface and gradually increasing it as the depth in-

creases. The maximum depth that SCC will affect is 75% of the selected

depth range. For example, on a 0-60 foot range with maximum SCC, sur-

face clutter will be reduced down to about 45 feet.

There are three levels of SCC available on the X-70A 3D: low, medium,

and high. When it’s turned on for the first time, the SCC level is low. To

change it, press the MENU key three times, then press the key adjacent

to the “SCC” label until the check mark is on the desired SCC level. Press

the CLR key when you’re finished.

ASP (Advanced Signal Processing)

The ASP feature is a noise rejection system built into the X-70A 3D that

constantly evaluates the effects of boat speed, water conditions, and in-

terference. This automatic feature gives you the best display possible un-

der most conditions.

The ASP feature 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 feature has two lev-

els - Low and High. 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 interfer-

ence source and fix it, rather

than continually using the unit

with the high ASP setting.

However, there are times

when you may want to turn the

ASP feature off. This allows

you to view all incoming echoes before they are processed by the ASP

feature.

To change the ASP level, press the MENU key three times. Then press

the key next to the “ASP” label until the desired level is obtained. Press

the CLR key to exit this menu.

FISHTRACK™

When the X-70A 3D is in the

2D or 3D modes and the Fish

ID feature is on, the depth of

the fish symbols can easily be

determined using the

FishTrack™ feature. This

places the depth above the

fish symbol as it appears on

the screen. It is normally on

when the unit is turned on. To

turn the FishTrack™ feature

off, press the MENU key two

times. Now press the key next

to the “FishTrack” label. This moves the check mark from the “ON” box to

the “OFF” box. To turn it on again, repeat the above steps.

TEMPERATURE GRAPH ADJUSTMENT

The temperature graph that appears beneath the digital surface water

temperature display has a range from 5 degrees higher than the current

temperature to 5 degrees lower than the current temperature, for a total of

ten degrees. This range can be changed from ten to two or four degree. To

change the temperature graph range, press the MENU key three times,

then press the key next to the "Temperature Graph" label until the check

FISHTRACK ON

mark is on the desired range. Press the CLR key to exit the menu.

RESET DISTANCE LOG

The X-70A 3D can display the log (distance travelled) in the digital block if

the optional speed/temperature sensor is installed. This feature starts

counting distance as soon as the unit is turned on. To reset the distance

log to zero, press the MENU key three times, then press the key adjacent

to the “Reset Distance Log” label. Press the CLR key to return to the

sonar display.

MENU - PAGE 4

3D ENHANCE

Although the X-70A 3D has

four transducer elements, the

display shows an enhanced

grid that adds points to the

grid. See the difference be-

tween the two screens shown

below. To remove the extra

lines and view only the depth

grid from the four elements,

first press the MENU key four

times. Now press the key next

to the “3D Enhance” label. The extra lines are erased from the display. To

turn the enhanced display on, simply repeat the above steps.

3D SIMULATOR

The X-70A 3D has a built-in simulator for the 3D display. When this simu-

lator is turned on, a realistic 3D view scrolls across the screen. The digital

depth display shows the simulated bottom depth, and fish symbols ap-

pear on the display.

IMPORTANT!

Do not use the simulator when navigating!

To turn the 3D simulator on, press the MENU key four times. Now press

the key next to the “3D Simulator” label to move the check mark from the

“OFF” box to the “ON” box. If you return to the 3D screen, the simulator

will be in operation.

To turn the 3D simulator off, press the MENU key four times. Now press

the key next to the “3D Simulator” label to move the check mark from the

“ON” box to the “OFF” box. If you return to the 3D screen, the simulator

will be off.

3D DISTANCE MARKERS

The X-70A 3D displays mark-

ers on the screen, showing the

approximate distance echoes

are behind the boat. (This re-

quires an optional speed/tem-

perature sensor.) When the

unit is turned on, the markers

are automatically displayed if

the speed/temp sensor is

plugged in. If you wish to turn

the markers off, press the

MENU key four times, then

press the key next to the "3D

Distance Markers until the check mark moves to the "OFF" box. Press the

CLR key to exit.

TROUBLESHOOTING

If your unit is not working, or if you need technical help, please use the

following troubleshooting section before contacting the factory customer

service department. It may save you the trouble of returning your unit.

Unit won’t turn on:

1. Check the power cable’s connection at the unit. Also check the wiring.

2. Make certain the power cable is wired properly. The red wire connects

to the positive battery terminal, black to negative or ground.

3. Check the fuse.

4. Measure the battery voltage at the unit’s power connector. It should be

at least 11 volts. If it isn’t, the wiring to the unit is defective, the battery

terminals or wiring on the terminals are corroded, or the battery needs

charging.

Unit freezes, locks up, or operates erratically:

1. Electrical noise from the boat’s motor, trolling motor, or an accessory

may be interfering with the sonar unit. Rerouting the power and trans-

ducer cables away from other electrical wiring on the boat may help.

Route the sonar unit’s power cable directly to the battery instead of

through a fuse block or ignition switch

2. Inspect the transducer cable for breaks, cuts, or pinched wires.

3. Check both the transducer and power connectors. Make certain both

are securely plugged in to the unit.

Weak bottom echo, digital readings erratic, or no fish signals:

1. Make certain transducer is pointing straight down. Clean the face of

the transducer. Oil, dirt, and fuel can cause a film to form on the trans-

ducer, reducing its effectiveness.

2. Electrical noise from the boat’s motor can interfere with the sonar. This

causes the sonar to automatically increase its Discrimination or noise

rejection feature. 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,

the digital will flash continuously. It may change the range to limits far

greater than the water you are in. If this happens, place the unit in the

manual mode, then change the range to a realistic one, (for example,

0-100 feet) and increase the sensitivity. As you move into shallower

water, a bottom signal should appear.

4. Check the battery voltage. If the voltage drops, the unit’s transmitter

power also drops, reducing its ability to find the bottom or targets.

Bottom echo disappears at high speeds or erratic digital reading or

weak bottom echo while boat is moving

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. The technical term for this is

Cavitation.

2. Electrical noise from the boat’s motor can interfere with the sonar. This

causes the sonar to automatically increase its Discrimination or noise

rejection feature. This can cause the unit to eliminate weaker signals

such as fish or even structure from the display. Try using resistor spark

plugs or routing the sonar unit’s power and transducer cables away

from other electrical wiring on the boat.

No fish arches when the Fish ID feature is off:

1. Make certain transducer is pointing straight down. This is the most

common problem if a partial arch is displayed.

2. The sensitivity may not be high enough. In order for the unit to display

a fish arch, it has to be able to receive the fish’s echo from the time it

enters the cone until it leaves. If the sensitivity is not high enough, the

unit displays the fish only when it is in the center of the cone.

3. Use the Zoom feature. It is much easier to display fish arches when

zoomed in on a small range of water than a large one. For example,

you will have much better luck seeing fish arches with a 30 to 60 foot

range than a 0 to 60 foot range. This enlarges the targets, allowing the

display to show much more detail.

4. The boat must be moving at a slow trolling speed to see fish arches. If

the boat is motionless, fish stay in the cone, showing on the display as

straight horizontal lines.

NOISE

A major cause of sonar problems is electrical noise. This usually appears

on the sonar’s display as random patterns of dots or lines. In severe cases,

it can completely cover the screen with black dots, or cause the unit oper-

ate erratically, or not at all.

To eliminate or minimize the effects of electrical noise, first try to deter-

mine the cause. With the boat at rest in the water, the first thing you should

do is turn all electrical equipment on the boat off. Make certain the engine

is off, also. Turn your X-70A 3D on, then turn off ASP (Advanced Signal

Processing). There should be a steady bottom signal on the display. Now

turn on each piece of electrical equipment on the boat and view the effect

on the sonar’s display. For example, turn on the bilge pump and view the

sonar display for noise. If no noise is present, turn the pump off, then turn

on the VHF radio and transmit. Keep doing this until all electrical equip-

ment has been turned on, their effect on the sonar display noted, then

turned off.

If you find noise interference from an electrical instrument, trolling motor,

pump, or radio, try to isolate the problem. You can usually reroute the

sonar unit’s power cable and transducer cable away from the wiring that

is causing the interference. VHF radio antenna cables radiate noise when

transmitting, so be certain to keep the sonar’s wires away from it. You may

need to route the sonar unit’s power cable directly to the battery to isolate

it from other wiring on the boat.

If no noise displays on the sonar unit from electrical equipment, then make

certain everything except the sonar unit is turned off, then start the en-

gine. Increase the RPM with the gearshift in neutral. If noise appears on

the display, the problem could be one of three things; spark plugs, alter-

nator, or tachometer wiring. Try using resistor spark plugs, alternator fil-

ters, or routing the sonar unit’s power cable away from engine wiring.

Again, routing the power cable directly to the battery helps eliminate noise

problems. 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. In nearly all cases, the cause

of the malfunction will be the location and/or angle of the transducer. The

face of the transducer must be placed in a location that has a smooth flow

of water at all boat speeds.
