Lowrance electronic X-3 <to

To turn the

digital display

off, or back on again, press 2nd-5.

N OTE

Even if

the

digital numbers are not

being displayed

on the

screen,

the

digital sonar will still continue to function. If the

digital loses the bottom

signal,

the chart display

will stop until the digital

finds the bottom. If the

digital numbers are

being displayed

on the

screen,

the chart display

will

stop, but the

digital will flash the last valid bottom

depth until it

regains

the bottom signal.

If the chart is in the

freeze mode,

the

digital display

will continue to show

the bottom depth

as it changes. It does not freeze when the chart does.

This

gives an accurate means of

determining

the precise bottom depth

all times. In

fact, the X-3 can be turned into a

digital sonar by pressing

2nd-0-5. This will clear the screen of all echoes, including

the bottom

signal, and increase the size of the numbers for

easier

viewing.

To display the bottom and other echoes

again, press

the

STOP/RESUME

key

in the chart section of the

keyboard.

ALARMS

The X-3 has two alarms,

a chart alarm and a

depth alarm. The chart

alarm requires

both an upper limit and a lower limit setting.

The alarm

then "sounds off" whenever

an echo (such

as a

fish) is detected inside

the

boundaries set

the upper

and lower limits.

The

depth alarm also allows an upper and lower limit but it sounds

whenever the bottom echo is detected

outside the boundaries set

the

alarm's upper and lower limits. Both chart and depth alarms can be

set,

then switched back and forth. However, they cannot be used simultane-

ously and will be treated

separately

in this section.

AUTO SENSITIVITY

Whenever the X-3 is in the

auto-sensitivity

mode, it

will

adjust the sensi-

tivity

of the unit to three

steps above the minimum

required

to pick

the

bottom

signal. (There

are 32 steps of

sensitivity available.)

The

sensitivity may

adjusted while the X-3 is in the

auto-sensitivity

mode. This may be desirable if the level of

sensitivity

that the X-3 picked

is not

enough

to show fish or other detail. Once the

sensitivity

has been

changed,

the X-3 will increase the

sensitivity enough

to

pick up

the bot-

tom signal,

then add the level that you programmed

in.

For

example,

if it

took the X-3 five steps

of

sensitivity

to find and lock onto

the

bottom,

it will add three more steps for a total of

eight If

desired,

any

amount of

sensitivity up

to 24

(for

a total of

32) may be added. Or, three

steps of

sensitivity

could be

subtracted,

however

only the bottom signal

would be

displayed

at this low

sensitMty setting.

There are two

ways of

adjusting

the

sensitivity

while the X-3 is in the

auto-sensitivity

mode.

The first is to press

either the right arrow key>

to increase the sensitivity

or press

the left arrow key

<to decrease it If the

value goes below the

minimum

required

to

keep the bottom

signal,

the X-3 will "chirp' The

same is true if

you try

to

go above 32 steps. As you press

the arrow key,

the

sensitivity

bar will move to

the left or right, according to the amount of

sensitivity

chosen.

The second method allows

you to enter the amount of steps using the

number keys on the keyboard.

For

example, to

adjust

the sensitivity

that it will

always be ten steps above the minimum

required

to lock onto

the bottom, press

the 1 -0-AUTO keys.

The

sensitivity

will then increase

to ten steps above the minimum

required,

instead of three. Remember,

the total number of

steps is 32.

OTHER

TIPS

If an incorrect entry

made,

wait six seconds for it to

disappear,

then

enter the

desired number. Or, press

2nd-O within six seconds of an entry

and it will erase the last keystroke.

Press 2nd-FAST or SLOW to display

the chart speed

bar without chang-

ing

the chart

speed.

When changing the upper or lower limits, remember the minimum dis-

tance between the two is ten feet. If a distance smaller than ten feet is

pressed,

the unit will move the range

to a ten foot separation.

For

exam-

ple, if the upper limit was 0 and 9-LOWER LIMIT was entered, the X-3

would disregard the 9 and set the lower limit to ten feet
