the time and date to their proper local settings. Once this is done, an

internal clock will keep

the correct time, even when the unit is turned off.

The GPS system updates this clock when the unit is locked on to the

satellites.

POSITION/NAVIGATION DISPLAYS

The AccuNav II has a

position screen, navigation screen, plotter, steering

indicator, and a satellite information screen. These displays were de-

signed

to show the most

important data. However, you can customize all

of them (except the satellite position screen) to some extent

through the

"Change Display" feature on the first GPS menu screen. (There are other

screens that can be customized by using

the Windows feature. See the

Windows section for more detail.) To customize these screens, see the

"Customize" section.

IMPORTANT!

If the data shown in

digital numbers on

any screen on this unit is

flashing,

then it means that data is invalid. Do not rely on that data if it is

flashing.

For example, if the position display is flashing, then the unit has lost the

satellites and

hasn't

re-aquired

them. The

position that is

flashing is

your

last known

position, notyourpresent position! Do not

navigate

with this unit

until you have found the reason the unit has lost the satellites!

Each of the

following screens is available by

first

pressing the MENU key,

then pressing the key next to the desired screen label. A detailed

description of each screen follows. (Press the MENU key twice to see the

Satellite Information menu.)
