DEPTH

ALARM. ALARM ALARM

The

depth

alarm is

actually

two alarms. The

shallow alarm gives

awarningwhenyou're

inwatershallowerthanthealarm set

point. Thedeep

alarm gives a

warning

in water at or

deeper

than

the alarm set

point. The

bottom signal is

the

only

echo that will

trigger

either the shallow or

deep

alarm.

NOTE: In orderto

usethe

depth

alarms, eitherthe

digital

orautomatic must

be on.

Selling

both

the shallow and

deep

alarms at the same time allows

a "window" to be positioned between the surface and

the bottom. If the

boat

goes

Into water

that is shallower than the shallow

alarm's

selling, the

alarmwill

sound. Adifferenttonewill sound if thebottom

goesdeeperthan

the

deep alarm setting. This makes a useful anchor watch. It is also

convenient when

navigating through

a

channel.

To use the shallow alarm, enter the

desired depth on the

10-key

pad,

then

pressthe

SHALLOWALARM

key. Forexample, to setthe shallow

alarm to 15

feet, press 1

,5,SHALLOW

ALARM.

The number 15

displays on

the screen as it's

entered, then disappears. The

letters "DA"

appear

in the

lower

portion

of

the screen to indicate it is activated. Now if the

boat moves

into water fifteen

feet deep or less, the alarm will sound and the words

"SHAL ALM" will

flash on the

display.

The

deep

alarm is used in the same manner. Enter the desired

depth,then pressthe

DEEPALARM

key. Forexample, tosetthe

deepalarm

to

feet, press

5, 0, DEEP ALARM. If the boat

moves into water 50 feet

deep

or

deeper, the alarm will

sound. The words "DEEP ALM" also flash

on the

display.

To view the settings of the shallow or deep alarms, press the

SHALLOW ALARM or DEEP ALARM

keys.

To turn each alarm off, press 0, SHALLOW ALARM or 0, DEEP

ALARM. The CLEAR

key

can

be used

in

place

of the 0

key, if desired. If both

shallow and

deep

the letters "DA" will

DISCRIMINATION Lm]

Unwanted noise on the display

is a fairly common

complaint.

Noise is

any undesired signal. It can be

caused by either an electrical or

acoustic

source, ora combination of the two. In both cases,

the noise can

produce

unwanted marks on the

display.

The

X-40 has Discrimination which is effective In

combating

noise

signals. It

processes all incoming echoes from the

receiver, determines

which ones are noise

and eliminates

them, displaying only

the

legitimate

echoes. Discrimination has ten levels -0

through 10. 0 is

off, 10 is

the

highestlevel. TurningtheX-4oonautomaticallysets Discriminationtolevel
