Getting started

Congratulations

on

your

purchase

of

the

system. Your

system

can

guide

you

to

the

destination

of

your choice

using

signals

from

Global

Positioning

Satellites

(GPS) orbiting

the

earth.

There

are

24

GPS

satellites

orbiting

the

earth.

A

GPS

device

can calculate

your

position

on

the

earth

if

it

can

receive

signals

from at

least

three

of

these

satellites.

When

it

receives

at

least

four signals,

a

GPS

device

can

also

calculate

your

altitude

(height above

sea

level).

To

use

the

system

for

the

first

time

you

need

to

charge the

battery,

install

the

map

loader

onto

your

computer,

and

install map

data

onto

the

system.

You

can

install

the

map loader

while

the

battery

is

charging.

Charging the battery

To

charge

the

battery,

plug

the

power

cable

into

the

system

and

when

the

battery

is

fully

charged.

Starting the system
