SAFETY INSTRUCTIONS
CAUTION
Use the correct fuse.
Use of the wrong fuse can cause fire or
equipment damage.
No single navigation aid (including this
unit) should ever be relied upon as the
exclusive means for navigating your
vessel.
The navigator is responsible for checking
all aids available to confirm his position.
Electronic aids are intended to assist, not
replace, the navigator.
Use of an autopilot with this unit, to
provide automatic steering to
destination, does not eliminate the
need to maintain a watch.
Always maintains a vigilant watch to
prevent collision or grounding.
Do not open the cover of the
equipment.
This equipment uses high
voltage electricity which can
shock, burn or cause death.
Only qualified person-
nel should work inside the
equipment.
WARNING
Do not dissasemble or modify the
equipment.
Fire, electrical shock or serious injury
can result.
Immediately turn off the power at the
ship’s mains switchboard if water or
foreign object falls into the equipment
or the equipment is emitting smoke or
fire.
Continued use of the equipment can
cause fire, electrical shock or serious
injury.
WARNING
To avoid electrical shock, do not
remove cover. No user-serviceable
parts inside.

FOREWORD
A Word to GP-150 Owners
Congratulations on your choice of the
FURUNO GP-150 GPS Navigator. We are
confident you will see why the FURUNO
name has become synonymous with quality
and reliability.
For 60 years FURUNO Electric Company has
enjoyed an enviable reputation for innovative
and dependable marine electronics
equipment. This dedication to excellence is
furthered by our extensive global network of
agents and dealers.
Your navigator is designed and constructed to
meet the rigorous demands of the marine
environment. However, no machine can
perform its intended function unless operated
and maintained properly. Please carefully
read and follow the recommended
procedures for operation and maintenance.
We would appreciate hearing from you, the
end-user, about whether we are achieving
our purposes.
Thank you for considering and purchasing
FURUNO equipment.
Features
The GP-150 GPS Navigator is a totally
integrated GPS receiver and video plotter
consisting of a display unit and an antenna
unit. The high sensitivity receiver tracks up to
12 satellites simultaneously. An 8-state
Kalman filter ensure optimum accuracy in
determination of vessel position, course and
speed.
In most cases the operator needs to do is to
turn on the power to find position.
The main features of the GP-150 are
• Comprehensive navigation data displays
• Storage for 999 waypoints and 30 routes
• Alarms: Waypoint Arrival, Anchor Watch,
Cross-track Error, Ship's Speed, Water
Temperature, Depth and Trip
• Man overboard feature records latitude and
longitude coordinates at time of man
overboard and provides continuous
updates of range and bearing to that point.
• DGPS capability - with built-in DGPS
beacon kit accepts DGPS correction data
from external DGPS beacon receiver
• Menu-driven operation
• Bright 122 x 92 mm LCD with temperature
compensated tone and brilliance
adjustment
• Power consumption is a low 10 W.
• Provision for connection of autopilot
(option) - steering data output to autopilot
• Digital display of water temperature and
depth with connection of echo sounder
(with NMEA input)
• Memory stores 2,000 points of track and
marks.
• "Highway" display provides perspective
view.
• Position may be shown in latitude and
longitude or LOP (Loran or Decca).
• Four connectors for optional equipment
two IEC 61162-1/NMEA 0183 I/O, one IEC
61162-1/NMEA 0183 (or log) output and
one DGPS for personal computer I/O
• Fully meets the following regulation:
IMO MSC. 112(73), IEC 61108-1 and IEC
62288.

1.2 Turning On and Off the
Power
The GP-150 takes about 90 seconds to find
position when turned on for the very first time.
Thereafter it takes about 12 seconds to find
position each time the power is turned on.
Turning on the power
Press the POWER key.
The unit tests the Program Memory, SRAM
and battery for proper operation and shows
the results on the display. If equipped with the
internal beacon receiver, "Beacon RCVR
Installed" appears at the bottom of the display.
The unit starts up with the last used display
mode.

Figure 1-2 Appearance of display when
turning on the power
When turning on the power the following
occurs:
12 seconds after turning on the power,
accurate position (in latitude and longitude)
appears on the display.
If position could not be found, "NO FIX" blinks
at the GPS receiving condition window. When
PDOP (Position Dilution Of Precision) value
exceeds 6 in the 3D mode or HDOP
(Horizontal Dilution Of Precision) value
exceeds 4 in the 2D mode, "DOP" blinks to
indicate abnormal fixing and the position
indication could not be updated.
When the satellite signal is being received
normally, one of the indications shown in
Table 1-1 appears depending on equipment
setting and GPS receiver state.

2.1 Enlarging/Shrinking the
Display
You may enlarge and shrink the display on
the Plotter 1, Plotter 2 and Highway displays,
with the ZOOM IN and ZOOM OUT keys. The
horizontal range is available among 0.25, 0.5,
1, 2, 4, 8, 16, 32, 64, 128 and 192 nautical
miles for Plotter 1 and Highway, and 0.36,

Plotter 2 display.
The ZOOM IN key enlarges the display and
the ZOOM OUT key shrinks it. Each time a
zoom key is pressed the display range
appears at the center of the display for about
one second.
2.2 Selecting Display
Orientation
Display orientation can be selected on the
Plotter 1 and Plotter 2 displays, with the
NU/CU ENT key. Two display orientations are
available: north-up and course-up.
North-up display
In the north-up display, true north (0°) is at
the top of the display. Own ship moves on the
display in accordance with true motion. (“TM”
appears at the bottom of the Plotter 1 and 2
displays.) Land is stationary.
Course-up display
Destination set
The destination is at the top of the display
and the north mark ( ) appears at the left
side of the display.
Destination not set
Ship's course is upward on the screen at the
moment the course-up mode is selected. The
north mark appears at the left side of the
display.
2.3 Shifting the Cursor
The cursor can be shifted with the cursor
pads.
1) Press the CURSOR ON/OFF key to turn
on the cursor.
2) Press the cursor pads.
The cursor moves in the direction of the
cursor pads pressed. When the cursor
reaches the edge of the display, the display
shifts in the direction opposite.
Data and cursor state
Cursor state determines what data are shown
on the display.
Cursor turned on, cursor data
Cursor position is displayed in latitude and
longitude or LOPs (depending on menu
setting) at the top of the display. The range
and bearing from own ship to the cursor
appear at the right hand side of the display,
when in the Plotter 1 display.

2.9 Selecting Track Plotting
Interval
The plotting interval determines both how the
track will be reconstructed on the display and
track storage time. A shorter interval provides
more accurate reconstruction of track line,
however total storage time is reduced. The
plotting interval can be selected by time or
distance. Plotting by distance offers the
advantage that the track is not stored when
the vessel is anchored.
Plotting interval by time
The setting range for plotting by time is 00 to
60 minutes.
