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
50
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

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
