7.5 Magnetic Variation

The location of the magnetic north pole is different from the geographical north pole. This causes a difference between the true and magnetic north direction. This difference is called magnetic variation, and varies with respect to the observation point on earth. Your unit is preprogrammed with all the earth's magnetic variation. However, you may wish to enter variation manually to refine accuracy. Set “BRG REF” on the PLOTTER is set to “MAG” to use magnetic variation.

1.Press the [MENU] key once or twice to open the menu.

2.Choose PLOTTER and then press the [ENT] key.

3.Choose MAG. VAR.

4.Press the [ENT] key.

5.Choose AUTO or MAN as appropriate and then press the [ENT] key. For automatic magnetic variation, current magnetic variation appears to the right of AUTO.

6.If you selected AUTO, no further operation is necessary; go to step 7. For MAN, press the [ENT] key and enter magnetic variation as follows:

a)If necessary, change coordinate from east to west or vice versa by pressing ▲ or ▼.

b)Press ► to shift cursor, use ▲ or ▼ to set value, referring to a nautical chart.

c)Press the [ENT] key.

7.Press the [MENU] key twice to finish.

7.6 Geodetic Chart System

Your unit is preprogrammed to recognize most of the major chart systems of the world. Although the WGS-84 system, the GPS standard, is now widely used other categories of charts still exist. Choose the chart system used, not the area where your boat is sailing. The default chart system is WGS-84.

1.Press the [MENU] key once or twice to open the menu.

2.Choose SYS SETUP and then press the [ENT] key.

a)Press the [ENT] key.

b)Use the cursor pad to enter chart number, referring to the geodetic chart list on page AP-3.

c)Press the [ENT] key.

6.Press the [MENU] key twice to finish.

7.7 Units of Measurement

Distance/speed can be displayed in nautical miles/knots, kilometers/kilometers per hour, or statute miles/miles per hour.

1.Press the [MENU] key once or twice to open the menu.

2.Choose SYS SETUP and then press the [ENT] key.

3.Choose UNITS.

4.Press the [ENT] key.

5.Choose combination desired; nm, kt; km, km/h; sm, mph.

6.Press the [ENT] key.

7.Press the [MENU] key twice to finish.
