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
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, including the 557/567
and 650, 657, 660. To reduce the risk of misusing or misinterpreting the 557/567 and 650, 657, 660, you
must read and understand all aspects of this Installation & Operation Manual. We also recommend that
practice all operations using the built-in simulator before using the 557/567 or 650, 657, 660.
Electronic Chart: The electronic chart used by 557/567 or 650, 657, 660 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 557/567 or 650, 657, 660 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.
AIS: The AIS features on this chart-plotter are designed as a safety aid only and do not guarantee safety
at sea. AIS transmission is mandatory on some, but not all, vessels. You should check your local laws and
regulations for requirements in your area. As a result of diff erent legal requirements, diff erent vessel sizes
and uses, you should not assume that your AIS equipped chart-plotter will show the location of ALL vessels
in your area. Careful prudence, judgement, and safe navigation practices should be always be exercised. AIS
should be used to complement radar, but AIS is not a substitute for radar.
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.

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 557/567 is connected to an autopilot, the
557/567 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 557/567 has no autopilot, steer the boat
manually:
a use the boat position and destination on
the chart or highway windows
b or use navigation data window on the data
header (see section 2-8-3)
c or use COG and BRG on the compass (see
section 2-8-4).
Note:
1 If the XTE alarm is enabled, an alarm will
sound if the boat deviates too much from its
intended course (see section 15-8).
2 If the arrival radius alarm is enabled, then an
alarm will sound to show that the boat has
reached the destination (see section 15-8).

3-5 Tracks and trackin g
Tracking records the boat’s position to memory at
regular intervals, which can be:
Time intervals.
Or distance intervals.
The track of where the boat has been can be
displayed on the chart. The 557/567 can display
one track while recording another.
To work with track s, see section 15-5.
The 557/567 can store five tracks:
Track 1 can hold up to 200 0 points and is
intended to record the normal progress of
the boat.
Tracks 2, 3, 4 and 5 can hold up to 500 points
each and are intended to record sec tions to
be retraced accurately, for example entering a
river mouth.
Tip: Record the tracks in good conditions.
When recording is on and the track becomes full
then recording continues and the oldest points
in the track are deleted. The maximum length of
a track depends on the selected track interval: a
small interval will give a shor ter, more detailed
track and a long interval will give a longer, less
detailed track, as shown in these examples:
The track lengths are in the current distance units,
for example nm.
