SECTION TWO: Installing and wiring the 957
Page 6 957 Installation Manual, Revision C1
Bench-testing the
957
Northstar recommends bench-testing the 957 before installing
it onto the vessel. Bench testing ensures that the equipment is
fully operational, and lets the 2201 antenna or 2701 beacon
receiver collect the current almanac and ephemeris data for the
installed location, which results in less on-board installation
time.
Mounting the 957
Choosing the best location Choose the mounting location carefully—before you drill or cut.
The display screen is high-contrast and anti-reflective, and is
viewable in direct sunlight, but for best results, install the 957
out of direct sunlight. See the figure below for additional
mounting recommendations.
CAUTION!
Make sure that the 957 doesn’t interfere with any
other on-board systems. Check all other systems to
ensure that their performance doesn’t degrade
when the 957 is turned on.
CAUTION!
Proper installation of the Northstar 957 is critical to
accurately receive and effectively use GPS/WAAS
signals under a wide variety of weather conditions.
