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
fishfinder.
Connection to the power source with reversed polarity
will damage the fishfinder severely. This damage is not
covered by the warranty.
Do not disassemble. The fishfinder 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 you 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.
Important
It is the owner’s sole responsibility to install and use the unit
in a manner that will not cause accidents, personal injury or
property damage. The user of this product is solely responsible
for observing safe boating practices.
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.

Presentation
Thank you for having purchased a GME product. This
handbook contains an explanation of how to install, operate
and maintain your unit.
SAFET Y INSTRUCTIONS
If you require technical advice or assistance, contact your
nearest GME dealer or visit our website, www.gme.net.au.
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.

1 - INTRODUCTION
1-1 General Information
Fishfinders use an echo-sounding technology which uses a
transducer to send ultrasonic sound waves through water.
The sound waves are reflected back the transducer when they
strike an object such as the bottom.

3-4 Sonar
The G142FD has a sonar function when the unit is connected
to a depth transducer.
3-4-1 Interpreting the display
Single fish: Fish symbols with depth.
Bottom: Hard bottoms such as rock and coral shown as wide
bands. Soft bottoms such as mud, weed and sand show as
narrow bands.
Depth range: Depth range of display.
The window scrolls from right (recent sonar record) to left (old
sonar record).
3-4-2 Mode
The unit operates in two different modes. You can choose a
mode depending on the conditions.
• Auto mode: This is the most commonly used option. In
this mode, settings are automatically adjusted for the best
display of fish and bottom according to the environment.
• Manual mode: Use this option for manual settings. This
option might bring you better results for the conditions.
To change a mode;
1 Press MENU then
select Gain.
2 Select Mode then
Manual or Auto
and press ENT.
3 Press ESC to exit.
3-4-3 Single and Dual frequency fish finding
Sonar frequencies
The G142FD is a dual frequency unit using both 200 kHz and
50 kHz to detect various bottom conditions at various depths.
To select the sonar frequency in sonar window:
1 Press MENU, select Frequency.
2 Select Frequency and press ENT.
3 Press ESC to exit.
High frequency (200 kHz )
The higher ultrasonic signal, the better the resolution. For this
reason the 200 kHz frequency is ideal for detailed observation
of fish schools.
Low frequency (50 kHz)
The lower frequency signal is a wider signal for a wider
detection area. Therefore, the 50 kHz frequency is useful for
general detection and judging bottom conditions.
Mixed frequencies (200 kHz / 50 kHz)
The Mixed frequency combines the 200 kHz and the 50 kHz in
the Sonar window.
Note: the 50 kHz signal will travel deeper than the
200 kHz signal.
The display is useful
for comparing the
same picture with two
different frequencies.
3-4-4 Range
Range is the depth of water displayed on the sonar window.
The basic range may be chosen in either Auto or manual mode.
Auto: When the mode is set to Auto, the unit adjusts the
depth automatically for the best performance. This option is
recommended for normal operation.
Manual: When the mode is set to Manual, the unit only
displays the depth of water at a chosen range. This could mean
that the sea bed is not displayed as it is out of range, as shown
on the following page.
