Configuring Units of Measure
To change units of measure from the Home screen, select
Configure > Preferences > Units �
System Units—a global setting that defines individual units of
measure at the same time: Statute (mh, ft, ºf), Metric (kh, m, ºC),
Nautical (kt, ft, ºf), or Custom. Select Custom to individually
define units of measure for depth, temperature, distance, speed,
elevation, volume, and pressure.
NOTE: You must be receiving NMEA sonar depth data to view
depth and water temperature information.
Heading—sets the reference used in calculating heading
information.
• auto Magnetic—automatically sets the magnetic declination for
your location.
• True—sets true north as the heading reference.
• grid—sets grid north as the heading reference (000º).
• User Magnetic—allows you to set the magnetic variation value.
Position format—change the coordinate style in which a given
location reading appears. Do not change the position format unless
you are using a map or chart that specifies a different position
format.
Map datum—change the coordinate system in which the map is
structured. Do not change the map datum unless you are using a map
or chart that specifies a different map datum.
Time—set the time options.
• Time format—select 12-hour, 24-hour, or UTC time format.
• Time Zone—set the time zone you want displayed for time
readings. If auto is selected for the Time Zone, the DST option
is not available and is automatically set to auto.
• dST (Daylight Saving Time)—select Off , On , or auto . The
auto setting automatically turns daylight saving time on or off,
depending on the time of year.
• baro. Ref. Time—specify the reference time (from 30 minutes
to 24 hours) used to calculate the barometric pressure trend.
The trend is displayed on the wind gauge when ground wind is
selected ( page 36 ) or on the Cruising data bar ( page 9 ).
