10.3 Selecting Navaid

If your boat is equipped with other position- fixing equipment you may wish to use its po- sition fixes instead.

1.Press the MENU key.

2.Press the [0] key.

3.Press the [2] key.

4.Operate the Cursor Pad to select NAVAID.

5.Operate the Cursor Pad to select OWN (internal GPS), LC (Loran C), DE (Decca), or ALL. (Select ALL for mul- tiple navaid connection. In this case posi- tion data is read in the order of GPS, Loran C, Decca, etc.)

6.Press the MENU key.

10.4Displaying True or Magnetic Bearings

You may display bearing relative to true North (true bearing) or relative to magnetic North (magnetic bearing).

1.Press the MENU key.

2.Press the [0] key.

3.Press the [2] key.

4.Operate the Cursor Pad to select BEAR- ING.

5.Operate the Cursor Pad to select TRUE or MAG.

6.Press the MENU key.

10.5 Magnetic Variation

The location of the magnetic pole is different from the geographical North pole. This causes a difference between the true and magnetic North direction. The difference is called mag- netic variation, and varies by the observation point on the earth. This unit is programmed with the earth's magnetic variations. However, you may wish to further refine variation for a particular area by entering them manually. If you enter compensation manually, be sure to change it when magnetic variation changes.

1.Press the MENU key.

2.Press the [0] key.

3.Press the [2] key.

4.Operate the Cursor Pad to select MAG CALIB.

5.Operate the Cursor Pad to select AUTO or MAN.

6.If you selected MAN in step 5, enter mag- netic variation with the numeric keys.

7.Press the ENT key followed by the MENU key.
