Menus change depending
on
the
mode
the
unit is in. For
example,
if
FISH ARCHES
the
automatic mode
is turned off,
the
sensitivity menu changes from
"AUTO SENS"
to
"MAN SENS."
Other messages
may appear
in
menu
boxes
or
new menus
can
appear, again depending
on
previous
selections.
OPERATION
Fish arches are
created when
the
cone
of
sound passes
over
a
fish.
The distance
to
a
fish when
the
cone first
strikes
it
is
shown
as
"A"
below. When
the
center
of the
cone
strikes
the
fish,
the distance
is
shorter
as
shown "B".
As
the
cone
leaves
the
fish,
the
distance
increases again
as shown
in
"C".
AUTOMATIC
When
the
X-25 is first turned
on,
the
auto-
matic feature is
enabled.
This
feature
automatically
adjusts
the
unit's range
and
sensitivity according
to
water
conditions.
It
always keeps
the
bottom depth displayed
in
the lower portion
of the
screen.
To
turn
the
automatic feature off, press
the
menu
key until
the
AUTO/MAN
menu
appears.
Now
press
the down
arrow key.
This
highlights
the
letters
"MAN." The
unit
is now
in
the
manual
mode. Wait
a
few
seconds and
the
menu
will
scroll
off the
screen's left side.
Pressing
the
ON/CLEAR
key
also
clears
it.
To
turn
the
automatic
feature on
again, repeat
the
above steps,
except
this
time
press
the up
arrow
key.
RANGE
You can't adjust the
range
when
the
X-25
is
in
the
automatic mode.
It
is
adjustable
when the unit is
in
the
manual mode,
however.
To do
so, first put
the
unit
in
the
manual
mode. Now press the
ON/CLEAR
key
to
clear
the
screen.
Then press the
menu
key
until
the
'RANGE SEL"
menu
appears as
shown.
The current
range
shows
at the
bottom
of the
menu. In
this
case,
the
range
is 60 feet. Now press the
up arrow key
to
decrease
the
range,
the
down arrow key
increases
the
range. After
you select
the
desired range, press
the

ID.
mode
is off, the
depth
of
the water will affect
the
size
and
shape
Qf
the
fish
arch
due
to
the
cone
angle diameter. For
example,
if
the cone passes over
a
fish
in
shallow water,
the
signal
displayed
on the X-25 may not
arch
at all. This is due to the
narrow
cone
diameter and
the
resolution limitations
of
the
display.
