When reading this manual, please pay particular attention to warn-
ings marked with the warning triangle. These are important mes-
sages for safety, installation and usage of the product.
Safety warnings
Warning: This equipment must be installed in accordance
with the instructions provided in this manual.
Warning: This AIS transceiver is an aid to navigation and must
not be relied upon to provide accurate navigation information.
AIS is not a replacement for vigilant human lookouts and other
navigation aids such as RADAR. The performance of the trans-
ceiver may be seriously impaired if not installed as instructed in
the user manual, or due to other factors such as weather and or
nearby transmitting devices. Compatibility with other systems
may vary and is reliant on the third party systems recognising the
standard outputs from the transceiver. The manufacturer reserves
the right to update and change these specifications at any time
and without notice.
Warning: Do not install this equipment in a flammable atmo-
sphere such as in an engine room or near to fuel tanks.
General notices
Position source
All marine Automatic Identification System (AIS) transceivers utilise a
satellite-based location system such as the Global Positioning Satel-
lite (GPS) network. The accuracy of a GPS position fix is variable and
is affected by factors such as the antenna positioning, the number
of satellites used to determine the position and for how long satel-
lite information has been received.
Compass safe distance
The compass safe distance of this unit is 0.2 m or greater for 0.3°
deviation.
