9. CUSTOMIZING YOUR UNIT
DEFAULT LATITUDE, DEFAULT LONGITUDE
The default latitude and longitude position is Seattle, U.S.A. (45°35.000’N,
125°00.000’W). When the unit is turned on for the first time it begins searching
for its actual position. To lessen the time required to find position, you may enter
your position manually. Use the [CURSOR ON/OFF] key to switch co-ordinate.
ANTENNA HEIGHT
Enter the height of the antenna unit above sea surface. For further details, refer
to the installation manual.
GPS FIX MODE
You can choose the position-fixing mode from 2D or 2D/3D. When selecting
2D/3D, 2D or 3D is automatically chosen depending on the number of available
satellites. (3D requires four or more satellites.)
DGPS/WAAS
Choose the position-fixing method among DGPS, WAAS and AUTO. DGPS
requires the optional DGPS receiver board. For WAAS, see the “WAAS Facility”
at the back of this manual.
AUTO fixes position by WAAS when DGPS correction data is not available.
For normal GPS positioning, select “OFF.”

signal is lost.
YES: Alarm sounds when the position fixing method is switched from WAAS to
DGPS or vice versa.
NO: Alarm sounds once when WAAS or DGPS signal is lost.
