Regulatory notices Regulatory notices When reading this manual please pay attention to warnings marked with the warning triangle shown on the left. These are important messages for safety, installation and usage of the product. Safety warnings This equipment must be installed in accordance with the instructions provided in this manual. - Page 6 Regulatory notices The accuracy of a GPS position fix is variable and is affected by factors such as the antenna positioning, how many satellites are used to determine a position and how long satellite information has been received for. The term GPS will be used in this manual to mean all and any GNSS systems.
- Page 7 Regulatory notices 1.2.4 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.

Page 18: Antennas
Installation 3.2 Antennas 3.2.1 VHF antenna Connection to a suitable VHF antenna will be required for the transceiver to receive and transmit. Transceiver variants (B921/B922/B951/B952) do not have an integrated splitter and will require a dedicated VHF antenna tuned to the AIS channels at 162MHz. Integrated splitter variants (B923/B924/B953/B954) will require a VHF antenna tuned to operate across the frequency range 156MHz to 162MHz. - Page 19 If your installation location is deep inside your boat where the GPS antenna will not be able to receive satellite signals you will need an external GPS antenna. We recommend the em-trak GPS100, which is available for purchase from www.em-trak.com.
- Page 20 Installation Please note the following guidelines when installing an external GPS antenna. •You will require a 1" (inch) 14 TPI threaded mount if you choose to pole mount the GPS antenna. •The GPS antenna is also supplied with a gasket/thumb nuts/ studs so it can be deck mounted.

- Page 56 The em-trak B900 Series transceivers are 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 performanceof the B900 series 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.
