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 informa-
tion. AIS is not a replacement for vigilant human lookouts and
other navigation aids such as RADAR. Also, take note that not all
vessels will have an AIS transceiver turned on, or installed. The
performance of the transceiver 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. Compatibil-
ity 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 0.5 m or greater for 0.3°
deviation.
