Global Positioning System: The Global Positioning System
(GPS) is operated by the US government which is solely
responsible for its operation, accuracy and maintenance.
The GPS system is subject to changes which could affect the
accuracy and performance of all GPS equipment anywhere in
the world.
Installation: If installation is not correct, the unit can not
perform at its designed potential. If in doubt, consult your
GME dealer. Ensure that any holes made are in a safe position
and will not weaken the boat’s structure. If in doubt, consult a
qualified boat builder.

SAFETY INSTRUCTIONS
If you require technical advice or assistance, contact your
nearest GME dealer or visit our website, www.gme.net.au.
Please read through this manual before the first
operation. If you have any questions, please contact the
customer service or your local dealer or distributor
Extensive exposure to heat may result in damage to the
chartplotter.
Connection to the power source with reversed polarity
will damage the chartplotter severely. This damage is not
covered by the warranty.
Do not disassemble. The chartplotter contains dangerous
high voltage circuits which only experienced technicians
must handle
Exposure of the display to UV rays may shorten the life of
the liquid crystals used in your plotter. This limitation is
due to the current technology of the LCD display.
Avoid overheating which may cause loss of contrast and,
in extreme case, a darkening of the screen. Problems
which occur from over heating are reversible when
temperature decreases.
Screen Cleaning Precautions
Use a tissue or lens cloth and a cleaning spray containing
Isopropanol (a normal spray cleaner sold for PC screens).
Fold the tissue or lens cloth into a triangular shape,
moisten the tip and use the index finger behind a corner
to move the tissue across the surface, in overlapping side
to side strokes. If the tissue is too wet, a noticeable wet
film will be left in its path and you will need to repeat the
process. If too dry, the tissue won’t glide easily, and may
damage the surface.

The chartplotter is a precision-crafted GPS chartplotter with a
high-performance receiver for the Global Positioning System
constellation of satellites, providing precise location data with
a host of navigation features. Some functions require optional
units and sensors installed on your boat.
The chartplotter can be connected to external devices
with NMEA0183 and NMEA2000 interface and display
information.
Examples.
• NAVTEX
• AIS receiver
• DSC VHF radio
• Transducer and sensors
• Autopilot

2 GETTING STARTED
2-1 Mounting the Unit
The chartplotter is supplied with a bracket and flush
mounting kit. You can choose a method of installation
according to your preference.
2-1-1 Bracket Mou nting
Before installing ensure the area the bracket is mounted to is
strong enough to support the weight of the GPS chartplotter.
After the location is found, attach the mounting base to the
area using the supplied hardware.
Mounting the display Unit:
1 Hold display and find mounting groove on back of display.
2 Gently push display onto bracket ensuring groove on back
of display slides onto bracket.
3. Turn knob clockwise to lock.
Removing the display unit:
1. Turn the unit off
2. Turn the knob counter clockwise
3. Pull the display unit off bracket.
Note: The G142C/G142CFD with an internal GPS antenna is
designed to be bracket mounted or flush mounted. However,
if you flush mount inside of your boat, GPS performance can
be reduced.
2-1-2 Flush Mounting
1 Find a suitable location for flush mounting, tape flush
mount template to location.
2 Drill a hole in the area of the cutout.
3 Cut out area with a jig saw.
4 Drill four holes as marked for mounting studs.
5 Install the mounting studs on the chartplotter and insert
them into the mounting holes.
6 Attach the chartplotter to the mounting location by
attaching the supplied hardware to the mounting studs.
Note:
1 If you flush mount, you will need an optional
external GPS antenna.
2 Before Drilling holes make sure there is enough space to
mount the chartplotter and that there are no obstructions.

2-4 Simulate Mode
Simulate Mode is good for practicing the use of the product
when the satellite signals and internal alarms are not
available. In the simulate mode, the unit turns the GPS
receiver off and ignores data from all optional devices.
Two simulate modes are available as below.
• Normal: Allows a user to practice the actual use of a
product without satellite connection.
• Demo: Boat travels along a given route at a given speed
and shows functions of the unit.
Do not try to navigate in simulate mode. While the
simulate mode is turned on, the GPS receiver is not
active.
2-5 Data Bar
Data bar displays useful navigation information at the top of
the display.

the data bar will not apply to all other windows.
2-6 Compass
The chartplotter computes compass direction from the
constellation of GPS satellites. For the GPS chartplotter to
compute direction, the vessel must be moving through
the water.
2-7 Multi window displays
The Chartplotter can display up to four windows at the
same time.
Adding a window
1 Press PAGE and select Add icon.
2 Select an icon you want to add.

display the new display will overwrite the old display.
2-8 Man overboard (MOB)
During navigation, the “MOB” feature provides a one-touch
method of storing a location, such as a point where a crew
member falls overboard. In this mode, the chartplotter places
a MOB point on the chart page and all the navigation data
shown is related to navigating back to this point, allowing you
to efficiently retrace your path to the MOB point.
MOB will not work if the unit does not have a GPS fix.
1 When you press MOB, a MOB waypoint is created.
2 When MOB is pushed and you are not in the Chart
window, the screen automatically changes to the Chart
window and the MOB waypoint is at the center of the
chart.
3 If an autopilot is connected, the unit sets the MOB waypoint
to the destination.
This may result in a sudden and dangerous turn.
Tip: If navigation to the MOB waypoint is cancelled, the MOB
waypoint is not removed from the waypoint list. To delete the
MOB waypoint, you need to delete it manually.
