The following settings are available:

•   Location Format—is used to change the coordinate system in 

which a given position reading is displayed. You should only 

change the position format if you are using a map or chart that 

specifies a different position format or wish to use a format you 

are familiar with. The default format is latitude and longitude 

in degrees, minutes, and thousandths of a minute (hddd°mm.

mmm’). The following additional formats are available: 

• hddd.ddddd°
• hddd°mm’ss.s”
• UTM/UPS
• British Grid
• Dutch Grid 
• Finnish KKJ27
• German Grid
• Irish Grid
• India Zone Grids
• Maidenhead

• MGRS
• New Zealand
• Qatar Grid
• RT 90 
• Swedish Grid
• Swiss Grid
• Taiwan Grid 
• Loran TD 
• User Grid
• W Malayan RSO

For additional information on Loran TD setup, see the Appendix.

•   Map Datum—allows you to manually select the datum 

reference used to determine a given position. The default 

setting is WGS 84. The unit automatically chooses the best 

datum depending upon your chosen position format. Datums 

are used to describe geographic positions for surveying, 

mapping, and navigation and are not actual maps built in the 

unit. Although over 100 datums are available (as listed in the 

Appendix), you should only change the datum if you are using 

a map or chart that specifies a different datum.
