Notices
When reading this manual, please pay particular attention to warnings marked with the warning triangle. These are important messages 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. 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. 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 Satellite (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 satellite information has been received.
Compass safe distance
The compass safe distance of this unit is 0.5 m or greater for 0.3°
deviation.
Notices | NAIS-400 User Manual
RF emissions notice
¼ Note: The AIS transceiver generates and radiates radio frequency elec-
tromagnetic energy. This equipment must be installed and operated
according to the instructions contained in this manual. Failure to do so
can result in malfunctioning of the receiver or personal injury.
¼ Note: Never operate the AIS transceiver unless it is connected to a
VHF antenna.
To maximise performance and minimise human exposure to radio
frequency electromagnetic energy you must make sure that the antenna is mounted at least 1.5 meters away from the AIS transceiver
and is connected to the AIS transceiver before power is applied.
The system has a Maximum Permissible Exposure (MPE) radius of 1.5
m. This has been determined assuming the maximum power of the
AIS transceiver and using antennas with a maximum gain of 3 dBi.
The antenna should be mounted 3.5 m above the deck in order to
meet RF exposure requirements. Higher gain antennas will require a
greater MPE radius. Do not operate the unit when anyone is within
the MPE radius of the antenna (unless they are shielded from the antenna field by a grounded metallic barrier). The antenna should not
be co-located or operated in conjunction with any other transmitting antenna. The required antenna impedance is 50 ohms.
Warranty
This product is supplied with standard warranty as defined in the
accompanying warranty information.
Warning: Any attempt to tamper with or damage the prod-
uct will invalidate the warranty.
Disposal of this product and packaging
Please dispose of the AIS transceiver in accordance with the
European WEEE Directive or with the applicable local regulations for
disposal of electrical equipment.
Every effort has been made to ensure the packaging for this product
is recyclable. Please dispose of the packaging in an environmentally
friendly manner.
Accuracy of this manual
The AIS transceiver may be upgraded from time to time and future
versions of the AIS transceiver may therefore not correspond exactly

cations Commission to input an MMSI that has not been properly
assigned to the end user, or to otherwise input any inaccurate
data in this device.

About your AIS class B transceiver
About AIS
The marine Automatic Identification System (AIS) is a location and
vessel information reporting system. It allows vessels equipped with
AIS to automatically and dynamically share and regularly update
their position, speed, course and other information such as vessel
identity with similarly equipped vessels. Position is derived from the
Global Positioning System (GPS) and communication between vessels is by Very High Frequency (VHF) digital transmissions.
There are a number of types of AIS device as follows:
• Class A transceivers. These are similar to class B transceivers, but
they are designed to be fitted on large vessels such as cargo ships
and large passenger vessels. Class A transceivers transmit at a higher
VHF signal power than class B transceivers and therefore can be
received by more distant vessels, and also transmit more frequently.
Class A transceivers are mandatory on all vessels over 300 gross
tonnes on international voyages and certain types of passenger vessels under the SOLAS regulations.
• Class B transceivers. Similar to class A transceivers in many ways,
but are normally lower cost due to the less stringent performance
requirements. Class B transceivers transmit at a lower power and at a
lower reporting rate than class A transceivers.
• AIS base stations. AIS base stations are used by Vessel Traffic Sys-
tems to monitor and control the transmissions of AIS transceivers.
• Aids to Navigation (AtoN) transceivers. AtoNs are transceivers
mounted on buoys or other hazards to shipping which transmit
details of their location to the surrounding vessels.
• AIS receivers. AIS receivers will generally receive transmissions
from class A transceivers, class B transceivers, AtoNs and AIS base stations but do not transmit any information about the vessel on which
they are installed.
• This NAIS-400 product is an AIS Class B transceiver.

Static and dynamic vessel data
There are two categories of information transmitted by an AIS transceiver: static and dynamic data.
The vessel’s dynamic data, which includes location, speed over
ground (SOG) and course over ground (COG), is calculated automatically using the installed AIS antenna.
Static data is information about the vessel which must be programmed into the AIS transceiver. This includes:
• Maritime Mobile Service Identity (MMSI)
• Vessel name
• Vessel call sign (if available)
• Vessel type
• Vessel dimensions
In most countries the operation of an AIS transceiver is included
under the vessel’s marine VHF licence provisions. The vessel on to
which the AIS unit is to be installed must therefore possess a current
VHF radiotelephone licence which lists the AIS system, vessel Call
Sign and MMSI number.
Warning: An MMSI number is required in order for the AIS
transceiver to operate. Please contact the relevant authority in
your country for more information.
Important information for US customers
There are specific laws in the USA regarding the configuration of AIS
class B transceivers. If you are a US resident and intend to use your
AIS class B transceiver in US waters, you should make sure that your
retailer has configured your product prior to supplying it to you. If
your AIS transceiver has not been pre-configured, please contact
your dealer for details of how to have it configured.
Warning: In the United States of America, the MMSI and
static data must only be entered by a competent installer. The
end user of the equipment is not authorised to enter their own
vessel data.
