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

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 _________________________

changTh

Aft rthe latitude

as LccEPT

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

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

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

a recalled

waypoint if the arrival alarm's

setting is .1 mile. The alarm

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

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

to the "SET LAT, LON, ALT,

TIME,

DATE' label. The screen

shown below

appears.

Using the menus on

this and following menu pages, you can

change the

Initial Position, 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.
