This section describes the menu items not previously described.
[Key Beep]: When a key is pressed, a beep sounds. You can turn on or off this beep.
[Language]: English and other languages are available.
[HDG/COG Ref]: You can display the bearing in true or magnetic. [True] is the bearing
measured using true North as the reference direction. "T" is displayed on the screen.
[Mag] is the bearing measured with magnetic north as the reference direction. "M" is
displayed on the screen.
[Magnetic Variation]: If you selected [Mag] on the previous menu item [HDG/COG
Ref], set the option of the [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 var-
ies with respect to the observation point on earth. Your unit is preprogrammed with all
the earth's magnetic variation. If you selected [Auto], the programmed value is used
to display magnetic bearing. However, you can enter variation manually to improve ac-
curacy, referring to the latest navigation chart. Select [Manual] and press the ENT key.
Use the Cursorpad (X) to move the cursor to the right and enter the variation.
