This handbook contains important information on the operation and
maintenance of your G-Series system. To get the best results in
operation and performance, please take the time to read this hand-
book thoroughly.
For full details of installation and system integration, refer to the
G-Series Installation Guide and the G-Series Commissioning

Navigation Aid
This product is intended to serve only as an aid to naviga-
tion. Use of specific features such as AIS overlay, radar,
and various cartographic aids are meant only to aid safety
and decision-making. These features cannot be relied
upon as complete or accurate as their use and availability
may vary locally. It is your responsibility to use caution,
sound judgement, official government charts, notices to
mariners and proper navigational skill when using this or
any other electronic device.
Product installation
This equipment must be installed in accordance with the
instructions in the G-Series System Installation Guide.
Failure to do so could result in poor product performance,
personal injury and/or damage to the vessel.
High voltage
The display unit and scanner unit contain high voltages.
Adjustments require specialized service procedures and
tools only available to qualified service technicians -
there are no user serviceable parts or adjustments. The
operator should never remove the display unit cover or
attempt to service the equipment.
Electromagnetic energy
The radar scanner transmits electromagnetic energy.
Ensure that the scanner has been installed according to
the recommendations given in the relevant scanner hand-
book. Avoid looking directly at the antenna.
Fishfinder sounder module
Removing the transducer cable from the rear of the fish-
finder sounder module whilst it is switched on can cause
sparks. Only remove the transducer cable after power has
been switched off. Ensure that the sounder module is
mounted where it is well ventilated and in an area free
from flammable vapors.
Water ingress
To prevent the ingress of water and consequent damage to
the display, ensure that the chart card door is firmly
closed. This can be confirmed by an audible click.
