NAIS-400 Instruction 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 an-
tenna 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 an-
tenna field by a grounded metallic barrier). The antenna should not
be co-located or operated in conjunction with any other transmit-
ting 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.

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
