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.
CAUTION
Do not place liquid-filled containers on
the top of the equipment.
Fire or electrical shock can result if a
liquid spills into the equipmtnt.
Do not place heater neat the equipment.
Heat can melt the power cord, which can
result in fire or electrical shock.
Do not operate the unit with wet
hands.
Electrical shock can result.
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.

FOREWORD
A Word to GP-80 Owners
Congratulations on your choice of the
FURUNOGP-80 GPSNavigator.We are con-
fident you will see why the FURUNO name
has become synonymous with quality and re-
liability.
For over 50 years FURUNO Electric Com-
pany has enjoyed an enviable reputation for
innovative and dependable marine electron-
ics 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 per-
formits intendedfunction unless operated and
maintainedproperly. Pleasecarefully readand
follow the recommended procedures for op-
eration 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-80 GPS Navigator is a totally inte-
grated GPS receiver and video plotter con-
sisting of a display unit and an antenna unit.
Thehigh sensitivity receiver tracks upto eight
satellites simultaneously. An 8-state Kalman
filter ensure optimum accuracy in determina-
tion of vessel position, course and speed.
In most cases the operator need do no more
than turn on the power to find position.
The main features of the GP-80 are
• Comprehensive navigation data displays
• Storage for 999 waypoints and 30 routes
• Alarms: Arrival, Anchor Watch, Cross-
track Error, Ship's Speed, Water Tempera-
ture, Depth, and Trip
• Manoverboard feature records latitude and
longitude coordinates at time of man over-
board and provides continuous updates of
range and bearing to that point
• DGPS capability—with built-in DGPS
beacon kit, or accepts DGPS correction
data from external DGPS beacon receiver
• Menu-driven operation
• Bright 122 x 92 mm LCD with tempera-
ture compensated tone and brilliance ad-
justment
• Power consumption is a low 10 W.
• Provision for connection of autopilot (op-
tion)—steering data output to autopilot
• Digital display of water temperature and
depth with connection of video 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 lon-
gitude 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

1.2 Turning On and Off the
Power
The GP-80 takes about two minutes to find
positionwhen turnedon forthe veryfirst time.
Thereafter it takes about 20 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.
*: This indication is only when beacon re-
ceiver is installed.
Figure 1-2 Appearnace of display when
turning on the power
When turning on the power the following oc-
curs:
20 seconds after turning on the power, accu-
rate position (in latitude and longitude) ap-
pears on the display.
When turning on the power the following oc-
curs:
20 seconds after turning on the power, accu-
rate position (in latitude and longitude) ap-
pears on the display.
If position could not be found, "NO FIX" ap-
pears at the GPS receiver condition window.
When PDOP value exceeds 6 in the 3D mode
or HDOP value exceeds 4 in the 2D mode,
"DOP" appears to indicate abnormal fixing
and the position indication could not be up-
dated.
Whenthe satellite signalis beingreceived nor-
mally, 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 and Plotter 2 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 0.36, 0.71, 1.42, 2.84,

The [ZOOM IN] key enlarges the display and
the [ZOOM OUT] key shrinks it. Each time a
zoomkey is pressed the display range appears
atthe center of the display for about three sec-
onds.
2.2 Selecting Display
Orientation
Display orientation can be selected on the
Plotter1, Plotter 2 and Highwaydisplays, with
the [NU/CU ENT] key. Two display orienta-
tions 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
displayin accordance withtrue speed and true
motion. 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 heading or course is at the top of the
display.The north mark appearsat theleft side
of the display.
2.3 Shifting the Cursor
Thecursor canbe shifted with the cursor keys.
1) Pressthe [CURSOR ON/OFF] key to turn
on the cursor.
2) Press the cursor keys.
The cursor moves in the direction of the cur-
sor key 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 set-
ting) 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.

2.7 Stopping/Starting Plotting
and Recording of Track
The GP-80 stores 2,000 points of track and
marks. When the memory becomes full the
oldest track is erased to make room for the
