Northstar Explorer 660 Installation and Operation Manual

It is the owner’s sole responsibility to install and use the instrument in a manner that will not cause ac-
cidents, personal injury or property damage. The user of this product is solely responsible for observing
safe boating practices.

Global Positioning System: The Global Positioning System (GPS) is operated by the US Government
which is solely responsible for its operation, accuracy and maintenance. The GPS system is subject to
changes which could aff ect the accuracy and performance of all GPS equipment anywhere in the world
including the Explorer 660. Whilst the Northstar Explorer 660 is a precision navigation instrument, it can
be misused or misinterpreted, which can result in its use being unsafe. To reduce the risk of misusing
or misinterpreting the Explorer 660, the user must read and understand all aspects of this Installation
and Operation manual. We also suggest that the user practice all operations using the built in simulator
before using the Explorer 660 at sea.

Electronic Chart: The electronic chart used by the Explorer 660 is an aid to navigation and is designed
to supplement the use of offi

cial government charts not replace them. Only offi

cial government

charts supplemented by notices to mariners contain the information required for safe and prudent
navigation. Always supplement the information provided by the Explorer 660 with other plotting sources
such as observations, depth soundings, radar and hand compass bearings. Should the information not
agree then the discrepancy must be resolved before proceeding any further.

Sonar fishfinder: The accuracy of the sonar depth display can be limited by many factors,
including the type of the transducers, the location of the transducers and water conditions. It is the user’s
responsibility to ensure the Explorer 660 transducers are installed and used correctly.

Fuel Computer: Fuel economy can alter drastically depending on the boat loading and sea conditions.
The fuel computer should not be the sole source of information concerning available fuel onboard and
the electronic information should be supplemented by visual or other checks of the fuel load. This is
necessary due to possible operator induced 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 other operator controlled ac-
tions that may render the device inaccurate. Always ensure that adequate fuel is carried 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.

The Explorer 660 is set up with default units of feet, °F (Fahrenheit), US gallons and knots.
