MARKER
An event marker function
is
included in the X-1 6 so
that events
may
be marked when desired.
To
use the
marker,
simply press
the
MARK
key
and a vertical line will
be
displayed
across the entire
page.
Hold the MARK
key
down
and a vertical
line will be
printed
for as
long
as the
key
is held
down.
Example:
Press: MARK
SCALE
The
numbers that indicate
the
depth
or scale
may
be
deleted if
desired.
Pressing
the SCALE
key
once will
stop
the
printing
of
the
scale numbers.
The scale
may
be
displayed again
by pressing
the
SCALE
key.
Remember,
the
scale
may
be
displayed
at
any
time
by pressing
the 2nd
key
and then
the SCALE
key.

MEMORY/RESET
The Lowrance X-16 has
an
internal
battery
that
keeps power
supphed
to the
memory
circuits
even when
the
power
switch is
turned off. The
power
cable
may
be
unplugged
from the unit and
the X-16 will
still remember the
last
settings
that were in effect
when the unit was
turned off or
removed from the
boat. To reset
the X-16's functions
to their
factory
settings,
turn the
unit on and
press
the 2nd
key
and
then
press
the MARK
key.
The unit will then
be set
up
as follows:

The SCC

on the

with

The maximum
effective

for
SCC is 255 feet.
The

should
immediately
be
seen. Use
only
the amount of SCC
required
to
reduce the

can be eliminated
by using
this

also.

SUPPRESSOR
The
Suppressor
is a
noise
suppression
system
consisting
of
a
patented pulse
length
discrimination
suppression
circuit.
It is the
same as the one
used on
all Lowrance
variable
suppression
flashers
and
graphs. Basically,
it
works on the
principle
that
most
noise
pulses
are of
relatively
short
duration, If the
receiver circuit can
be
adjusted
so that it
will
accept
only
long pulses,
then the short
pulses
will be
cancelled
out,
and
only
the
desired
information
(fish,
bottom, structure,
etc.)
will be
displayed.
Of
course,
the
transmitter's
pulse length
would
have to
be increased at the
same
time
so that the return
echoes
would be
accepted
by
the
receiver.
This is
exactly
what the
Lowrance
suppression
system
does. The
transmitter's
pulse
length
is
increased
by using
the
keyboard,
and
the receiver 'tracks"
the amount of
increased
pulse
length, cancelling
out
any
narrow
noise
pulses,
and
displaying only
the
return echoes
from fish or the
bottom,
etc.
(Note:
receiver
sensitivity
is not
diminished at all
by
this
process.)
Noise,
in electronic
terms,
is
any
undesired
signal.
It can be
caused
by
an electrical
source,
(such
as the
engine's ignition
system)
or
by
air bubbles in
disturbed
water which is called
cavitation.
In both
cases,
the
noise
could
produce
unwanted marks
on
the
paper. (See
Figures
39
&
40.)
Fortunately,
noise
pulses
are
relatively
short in
time
compared
to real sonar
signals. Increasing
the
Suppression
will cause the
system
to
reject
these
unwanted,
short
pulses
without
reducing
the
sensitivity
in
any way.
This
patented design
is
exclusive with Lowrance.
However,
with
high suppression
settings,
