CHANGE POSITION
ARRIVAL ALARM
Use a chart to determine
your position
if
you
don't know
it. The latitude!
longitude
that
you
enter doesn't have to be
extremely
accurate.
Typically,
if
you
enter a
position
within one
degree
of
your present position,
the
AccuNav II should
quickly
find
your
actual
latitudeflongitude.
To
change
your present position,
first
press
the
key
next to the "CHANGE LAT"
label.
The screen shown below
appears.
Use the down
arrow
key
to
change
the
"N" to
"5",
if
necessary.
Next,
simply
enter
your present
lati-
tude
using
the numbered
keys.
Noticethatthe
position
entered
is in
degrees,
minutes,
and
hundredths of a minute.
(Not
_____________________________
seconds!)
If
you
make a mis-
take,
press
the left or
right
ar-
row
keys
to move to the num-
ber in the latitude that needs

next to the "ACCEPT' label.
Now
press
the
key
next to the
"CHANGE LON"
label. The black box will be next to the "E" on the
longitude. Again,
use the
up
or down arrow
keys
to switch the "E" to "W"
or west
longitude,
if
necessary.
Now enter the
longitude using
the
numbered
keys.
Be certain to enter a zero "0" as the first number in the
longitude
if it's less
than
100
degrees! Afteryou've
entered the last
number,
press
the
key
next to the "ACCEPT' label.
CHANGE ALTITUDE
To
enter
your present altitude, press
the
key
next to the "CHANGE ALT"
label. The AccuNav II needs to know
your
elevation above sea level.
(Not
your height
above
the
ground.) Again,
an
approximation
is
usually
suffi-
cient.
Use
the numbered
keys
to enter
your
altitude data. Press the
up
arrow
key
if
your
altitude is below sea level. For
example,
suppose
you're
in Death
Valley
and the
spot you're standing
in is 35 feet below sea level.
You would need to
enter the
numbers
"35",
then
press
the
up
arrow
key
to
change
itto -35 feet. Pressthe
key
nexttothe "ACCEPT" label when
you're
done.
CHANGE TIME
To
change
the local time
(the
time at
your position), press
the
key
next to
the
"CHANGE TIME" label. The screen shown at the
top
of the next
page
appears.
The arrival alarm sounds a tone when
your position
is within the alarm's
radius of a
waypoint.
For
example,
the alarm sounds if
you
come within .1
mile
of
a recalled
waypoint
if the arrival alarm's
setting
is .1 mile. The alarm
is
adjustable
from .01 to 9.9 miles.
XTE ALARM
The XTE
(cross
track
error)
alarm sounds a tone when
your
cross track
error is
greater
than the alarm's
setting. Changing
the
XTE alarm
also
changes
the XTE
range
on the
steering
screen. The alarm is
adjustable
from 0.0 to 9.9 miles.
ANCHOR ALARM
The anchor alarm sounds a tone when the
present position
moves outside
a
preset
radius. For
example,
if
you
set the anchor alarm to .1 nautical mile
(600 feet),
then the alarm will sound if
you
move more than 600 feet from
the location where
you
set the alarm. It's
adjustable
from 0.01 to 9.9 miles.
CHANGING GPS SETTINGS
The AccuNav II must be initialized when it's turned on forthe firsttime. This
is described at the
beginning
of the GPS section in this manual.
However,
ifyouwishto change only
one of
the
parameters (such
as
time),
use the menu features in the
"CHANGE SETUP" menu. To
do
this,
press
the MENU
key,
then
press
the
key
next to the
"CF-lANGE GPS SETTINGS" la-
bel.
Finally, press
the
key
next
to the "SET
LAT, LON, ALT,
TIME,
DATE' label. The screen
shown below
appears.

Using

menus on
this
and
following
menu
pages, you
can
change
the
Initial

Time-Date-Time
Offset,
or Altitude without
affecting any
other initialization
setting.
All of these menus work
identically
to the ones
described in the initialization section at the
beginning
of the GPS section.
After
you
make a
change,
the unit returns to the GPS or
plotter
screen.
You
may
need to re-initialize the unit if
you
move a
long
distance
(over
100
miles)
with the unit off. In this
example you
would need to enter a new initial
position
to
help
the AccuNav II find the correct satellites
quicker.
