FCC Statement
Note: This equipment has been tested and found to comply with the limits for a Class B digital device,
pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against
harmful interference in a normal installation. This equipment generates, uses and can radiate radio
frequency energy and, if not installed and used in accordance with the instructions, may cause harmful
interference to radio communications. However, there is no guarantee that interference will not occur in
a particular installation. If this equipment does cause harmful interference to radio or television reception,
which can be determined by turning the equipment off and on, the user is encouraged to try to correct
the interference by one or more of the following measures:
Reorient or relocate the receiving antenna.
Increase the separation between the equipment and receiver.
Connect the equipment into an output on a circuit different from that to which the receiver is
connected.
Consult the dealer or an experienced technician for help.
A shielded cable must be used when connecting a peripheral to the serial ports.
Important
It is your sole responsibility to install and use Northstar’s instrument and GPS antenna in a manner that
will not cause accidents, personal injury or property damage. Always observe safe boating practices.
The choice, location, angle and installation of the instrument & GPS antenna are critical to
performance of the system as intended. Follow instructions in this manual carefully. If in doubt,
consult your Northstar dealer.
Ensure that any holes cut are in a safe position and will not weaken the boat’s structure. If in doubt,
consult a qualifi ed boat builder.
Global Position System: The global Position System (GPS) is operated by the U.S. Government
which is solely responsible for its operation, accuracy and maintenance. The GPS is subject to changes
which could aff ect the accuracy and performance of all GPS equipment anywhere in the world. To
reduce the risk of misusing or misinterpreting the Explorer, you must read and understand all aspects
of this Installation & Operation Manual. We also recommend that you practice all operations using the
built-in simulator before using the Explorer.
Electronic Chart: The electronic chart used by Explorer is an aid to navigation designed to
supplement, not replace offi cial government charts. Only offi cial government charts supplemented
by notices to mariners contain the information required for safe and prudent navigation, Always
supplement the electronic information provided by Explorer with other plotting sources such as
observations, depth soundings, radar and hand compass bearings. Should the information not agree,
the discrepancy must be resolved before proceeding any further.
Fuel Computer: Do not rely on the fuel computer as the sole source of information regarding
available fuel onboard. Fuel economy can change drastically depending on boat loading and sea
conditions. Fuel Computer information should be supplemented by visual or other checks of the fuel
load. This is necessary due to possible operator errors such as forgetting to reset the fuel used when
fi lling the tank, running the engine with the Fuel Computer not switched on, or on other operator
actions that may render the device inaccurate. Always carry adequate fuel onboard for the intended
trip, plus a reserve to allow for unforeseen circumstances.
Failure to adhere to these warnings may lead to death, serious injury or property damage.
Northstar disclaims all liability for installation or use of this product that causes or
contributes to death, injury or property damage or that violates any law.
As Northstar is continuously improving this product we retain the right to make changes to the
product at any time which may not be refl ected in this version of the manual. Please contact your
nearest Northstar offi ce if you require any further assistance.

position as a waypoint called MOB.
2 The Explorer 538/538i changes to the chart
display, with the MOB waypoint at the centre
of the chart.
The chart zooms in for accurate navigation.
If the chart can not show the required
small scale, the Explorer 538/538i changes
to plotter mode (a white display with
crosshatching and no chart details, see
section 14-2).
3 The Explorer 538/538i sets the MOB waypoint
to be the destination to navigate to.
If the NMEA output (autopilot) is off (see
section 14-9) use the Explorer 538/538i to
manually navigate to the destination MOB
waypoint (see sections 3-1-1 and 3-1-2).

3 Navigation: Chart
The chart display shows the char t, the boat’s position course and navigation data.
3-1 Overview of navigating
The Explorer 538/538i has two ways of navigating, going straight to a point or following a route.
3-1-1 Navigating to a point
When the Explorer 538/538i is navigating to
a point, the char t and highway displays show
navigation data:
A The boat position .
B The destination point marked with a circle.
C The boat’s plotted course to the destination.
D Two CDI lines, parallel to the boat’s plotted
course, which indicate the maximum
expected deviation from the plotted course.
For more information, see appendix C.
If the Explorer 538/538i is connec ted to an
autopilot, the Explorer 538/538i will send data to
the autopilot to steer the boat to the destination.
Start the autopilot before starting to navigate to
the point.
If the Explorer 538/538i has no autopilot, steer the
boat manually:
a use the boat position and destination on
the chart or highway displays
b or use navigation data displayed on the
data header (see section 2-8 -2)
c or use COG and BRG on the compass (see
section 2-8-3).
3-1-2 Going to a waypoint or to a p oint on the chart
A waypoint is a position that you can set on the
Explorer 538/538i chart, for example a fishing
spot or a point on a route (see section 5).
Going to a waypoint from the chart display

the start of the route.
Navigating
The Explorer 538/538i navigates to each waypoint
on the route in turn as described in section 3-1-1.
The Explorer 538/538i stops navigating to the
waypoint at the end of the current leg and starts
the next leg of the route:
a when the boat comes within 0.025 nm of the
waypoint
b or when the boat passes the waypoint
