Calculate Area

The GPS can now calculate an area using the track log.  

Before using the CALC AREA feature you need to clear the track 

log. Please refer to your GPS Owner’s Manual for directions on 

clearing the track log.

 To calculate an area the GPS needs to have a non-linear 

track.  The GPS will measure the area enclosed between the 

fi rst and last points in a track log.  If you are intending to use 

the CALC AREA feature, do not let the track log cross over 

itself.  This will cause the unit to subtract and will falsify the 

readings. 

The unit used to measure the area can be determined 

automatically by the GPS or manually set by the user.

To calculate an area:

1.  From the Map Page, highlight the ‘OPT’ selection at the top 

of the screen and press 

ENTER

.

2. Highlight ‘TRACK SETUP’ and press 

ENTER

.

3. Highlight ‘CALC AREA’ and press 

ENTER

.

To change the area measuring units:

1.  Highlight the ‘UNITS’ fi eld in the CALC AREA menu and 

press 

ENTER

.

2.  Using the 

ROCKER

, select the unit that you desire and 

press 

ENTER

.

Power Save

A new feature ‘Power Save’ has been added in the System 

Setup Menu.  Power Save optimizes the GPS receiver to con-

serve battery power.  You may notice some delay in screen 

updating when making a sudden turn, but use of the Power 

Save feature should not negatively affect operation under 

normal circumstances.

To activate the Power Save feature:

1. Press the 

PAGE

 key to display the SETUP MENU.

2. Select ‘SYSTEM SETUP’ and press 

ENTER

3. Highlight the ‘MODE’ fi eld and press 

ENTER

.

4.  Using the 

ROCKER

 select ‘Power Save’ and press 

ENTER

.
