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.

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.

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.

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.

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.
