Page 143

The Military Grid Reference System (MGRS) uses two grid lettering schemes, referred to as standard and standard + 10 MGRS on this unit. Your position and datum in use determines which one to use. If you use standard and your position is off significantly, then try the alternate.

NOTE:

When the position format is changed, it affects the way all positions are shown on all screens, including waypoints.

To change the coordinate system, press ENT while COORDINATE SYSTEM is highlighted. Use ↑ ↓ to highlight the desired format. Press ENT to select it.

To setup Loran TD:

NOTE:

If the Loran TD conversion is chosen, you must enter the local Lo- ran chain identification for the master and slaves. Do this by se- lecting Setup Loran TD at the bottom of the Coordinate System menu, then selecting the desired ID. Press EXIT to close this menu.

Configure Loran TD menu.

Map Fix

Map Fix is used with charts or maps. This system asks for a reference position in latitude/longitude, which you take from a marked location on the map. It then shows the present position as distance on the map from that reference point.

For example, if it shows a distance of UP 4.00" and LEFT 0.50", you then measure up four inches and to the left a half-inch from the refer- ence point on the map to find your location.
