AIS Overview

The AIS feature enables you to receive information broadcast by
other vessels, and to view these vessels as targets relative to your
boat. The AIS feature on i70 is standalone, settings and alarms
cannot be shared with other AIS enabled products on your system.
How AIS Works
AIS uses digital radio signals to broadcast 'real-time' information
between vessels and shore-based stations via dedicated VHF radio
frequencies. This information is used to identify and track vessels in
the surrounding area and to provide fast, automatic and accurate
collision avoidance data.
Note: It may not be mandatory for vessels to be fitted with
operational AIS equipment. Therefore, you should not assume
that your multifunction display will show ALL vessels in your area.
Due prudence and judgement should be exercised.
With an optional AIS unit connected to your system you can:
• Display targets for any other AIS—equipped vessels.
• Display voyage information being broadcast by these targets,
such as their position, course, speed and rate-of-turn.
• Display basic or detailed information for each target vessel,
including safety-critical target data.
• Set up a safe zone around your vessel.
• View AIS alarm and safety-related messages.
AIS information is displayed on the screen as shown below:
