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.

GME DISCLAIMS ALL LIABILITY FOR ANY USE OF THIS
PRODUCT IN A WAY THAT MAY CAUSE ACCIDENTS,
DAMAGE OR THAT MAY VIOLATE THE LAW.

Governing language: This statement, any instruction
manuals, user guides and other information relating to the
product (documentation) may be translated to, or has been
translated from, another language (translation). In the event
of any conflict between any translations of the documentation,
the English language version of the documentation will be the
official version of the documentation. This manual represents
the installation procedures as at the time of printing. GME

Presentation

Thank you for having purchased a GME product. This
handbook contains an explanation of how to install, operate
and maintain your unit.

SA FETY IN STRUC TIONS

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
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.

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 - INTRODUCTI ON

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.

G142FD is supplied with bracket and flush mount Kit. You can
choose a method of installation according to your preference.

2-1-1 Bracket Mounting

Before installing ensure the area the bracket is mounted to is
strong enough to support the weight of the fishfinder. After the
location is found, attach the mounting base to the area using
the supplied hardware.

Mounting the display Unit:

1 Hold the display unit and find mounting

groove on back of display.

2 Gently push the display unit into the

bracket ensuring groove on back of
display slides into bracket.

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

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.

High Frequency (200 kHz)

Low Frequency (50 kHz)

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.

The gain menu

The gain is the amount of signal strength received from the
transducer and the threshold is the level of ultrasonic signal
that is ignored by a set value.

When you use the manual mode and threshold, the values of
gain and threshold need to be set very carefully.

In the Gain window, you can set the
gain and threshold.

To change a value:

1 Press MENU, select Gain or press

3-4-7 No split

No split window displays a sonar history at a given frequency
(50 or 200 kHz)

Low Frequency (50 kHz)

The 50 kHz frequency is ideal for detecting the wider area
which means low frequency is useful for general detection
and judging bottom condition. This frequency is also good for
deeper water.

High Frequency (200 kHz)

The 200 kHz frequency will provide a better resolution which
means it is ideal for the observation of fish or fish schools. This
frequency is also good for shallow water.

To set a frequency for this display:
