LOCAL TIME OFFSET

GPS uses UTC time. If you would rather use local time, enter the time difference between local time and UTC time. Use the soft key +<-->- to switch from plus to minus and vice versa.

GEODETIC DATUM

Your equipment is preprogrammed with most of the major chart systems of the world. Al- though the WGS-84 system, the GPS stan- dard, is now widely used other categories of charts still exist. Select the chart system used, not the area where your boat is sailing. The default chart system is WGS-84.

1.Select GEODETIC DATUMS.

2.Press the soft key EDIT to show the geo- detic datum window.

4.Press the soft key ENTER or the [ENTER] key to register your selection.

POS SMOOTHING

When the DOP or receiving condition is un- favorable, the GPS fix may change greatly, even if the vessel is dead in water. This change can be reduced by smoothing the raw GPS fixes. A setting between 000 to 999 is available. The higher setting the more smoothed the raw data, however too high a setting shows response time to change in latitude and longitude. This is especially no- ticeable at high ship’s speeds. 000 is the normal setting; increase the setting if the GPS fix changes greatly.
