Item	Description
POSITION FIXING	Selects position fixing mode.
MODE	2D: Position fixing by three satellites in line-of-sight of GPS receiver.
	3D: Position fixing by four satellites in line-of-sight of GPS receiver. Position-
	fixing availability shorter than 2D but highter accuracy.
	2D/3D: Position fixing by 2D or 3D (3D when available).
GEODETIC DATUM	Selects geodetic datum system.
	WGS-84 (Standard chart system for GPS)
	WGS-72 (Worldwide chart system)
	TOKYO
	NAD (North America 1992)
	EURO (European 1950)
	AUST (Australian Geodetic 1984)
	MISC (See page 10-9.)
HDOP	Index for position-fixing accuracy. When the HDOP threshold is lower than
THRESHOLD	the preset HDOP, the indication “2D” is replaced by “DOP” to show that
	position-fixing accuracy is poor. The default setting is 20, which is suitable for
	most all conditions.
TIME DIFFERENCE	GPS uses UTC time (world time standard). If you would rather display
	satellite schedule in local time, enter time difference between UTC and local
	time. If local time is earlier than UTC time enter a minus sign before entering
	time difference.
LATITUDE	For entering ship’s estimated latitude at cold start.
LONGITUDE	For entering ship’s estimated longitude at cold start.
DELTA LATITUDE	Enters difference between displayed latitude and chart position. The icon “L/L”
	appears at the bottom right-hand corner when delta latitude is being used.
DELTA	Enters difference between displayed latitude and chart position. The icon “L/L”
LONGITUDE	appears at the bottom right-hand corner when delta longitude is being used.
SMOOTHING	Changes difference between to eliminate errors in GPS position due to
	changes of speed and course.
ANTENNA HEIGHT	Enters antenna height above the waterline.
COLD START	Manually cold starts the GPS receiver to receive the Almanac. (Cold start is
	automatically done after clearing the GPS memory or at initial power
	application after installation.)
CST SATELLITE	Manually selects satellite to use for cold start, to reduce time required to
NO.	complete cold start.
