1 Introduction 1-1 Overview The Northstar Explorer 538 is a compact, rugged, highly integrated marine chartplotter. It is easy to use and has a Color display. Complex functions can be performed with a few key presses, taking the hard work out of boating.
Handle plug-in cards carefully. Keep them in their protective cases when not plugged into the Explorer 538/538i. Keep the holder in place in the Explorer 538/538i at all times to prevent moisture from entering the card compartment. Turn the Explorer 538/538i off (see section 2-3).
Start an action or accept a change. Zoom in or out to display diff erent areas and detail on the chart. Man overboard (MOB, see section 2-5). Turn Explorer 538/538i on and off (see section 2-3); adjust the backlighting (see section 2-4).
2-3 Turning on and off / auto power Turning on manually If the Explorer 538/538i is not wired for auto power, press to turn the unit on. If necessary, adjust the display to be easy to read (see section 2-4).
No: Use the Explorer 538/538i to manually navigate to the destination MOB waypoint (see sections 3-1-1 and 3-1-2). Yes: The Explorer 538/538i asks if the boat is to go to the MOB waypoint. Select: Yes: to immediately start navigating to the MOB waypoint.
2-7 Simulate mode In Simulate mode, the Explorer 538/538i ignores data from the GPS antenna and other transducers and sensors and the Explorer 538/538i generates this data itself. Otherwise, the Explorer 538/538i functions normally. There are two simulate modes: Normal: Allows a user to become familiar with the Explorer 538/538i off the water.

To turn the data off or on or to change what data is displayed, see section 2-8-2 Compass (see section 2-8-3) Chart scale (see section 3-2-3) Boat position (see section 3-2-1) Boat track (see section 3-5) Boat course and CDI lines (see Appendix C, CDI).
Page 19
3-2-1 Chart modes The Chart has two modes: Centre on boat mode To switch to centre on boat mode in the chart display, press . The boat is at the centre of the chart. As the boat moves through the water, the chart automatically scrolls to keep the boat in the centre of the chart.
3-2-5 Finding places To see places near the boat’s position, press to switch to centre on boat mode. To see places near a different point, move the cursor to that point on the chart. To find and display places of interest: Press and select Find.
Time intervals. Or distance intervals. The track of where the boat has been can be displayed on the chart. The Explorer 538/538i can display one track while recording another. To work with tracks, see section 14-5. The Explorer 538/538i can store five tracks:...
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. The Explorer 538/538i can have up to 3000 waypoints. A waypoint can be created, changed or deleted. A waypoint has: A name (up to eight characters).
5-1 Waypoints display To go to the waypoints display, press , select Other, then select Waypoints. The waypoints display is a list of the waypoints that have been entered, each with waypoint symbol, name, latitude and longitude, distance and bearing from the boat, type and display option.
Page 24
Or, in the Chart display, press Find, then select Waypoints. Select a waypoint from the list. The Explorer 538/538i switches to the chart display, with the selected waypoint at the centre of the chart. Deleting a waypoint from the chart display In the chart display, move the cursor to the waypoint to delete.
A route is a list of waypoints that the boat can navigate along. Routes can be created, changed and deleted. The Explorer 538/538i can have up to 25 routes. Each route can have up to 50 waypoints. A route can: Start and stop at the same waypoint .

DGPS A DGPS system uses correction signals to remove some of the errors in the GPS position. The Explorer 538/538i can use one of two types of DGPS system: WAAS and EGNOS DGPS WAAS and EGNOS are two satellite based DGPS systems.
7-1 Satellite display The satellite display has information about the GPS satellites and GPS position. To go to the satellite display, press Other, then select Satellite. The satellite display shows: Northstar Explorer 538i/538 Installation and Operation Manual A Status of GPS antenna, for example Acquiring, GPS fix, No GPS.
8 Gauges display The Gauges display shows boat data, such as water speed, as analog or digital gauges. To go to the Gauge display, press select Chart , then select Chart+Gauges. If necessary, press twice to switch to the Gauges display (see section 2-8-1). Before using the Gauge display, set Speed range and Max fuel flow (see section 17-11).
9 Data display 10 Fuel functions and display The Fuel functions require optional fuel sensors to be installed. 10-1 When you add or remove fuel When you add or remove fuel in a boat with no SmartCraft fuel tank level sensors, you must tell the Explorer, otherwise REMAINING, RANGE and the low fuel alarm will be meaningless.
This is useful for checking that both engines are under the same load. Speed If the Explorer 538/538i has both GPS and paddlewheel speed available then you can select which to use. The choice affects the calculated Range and Economy (see section 17-5 Speed source).
Enter the comfortable maximum RPM you have measured for the engine. Do not use the maker’s maximum RPM. The Explorer 538/538i then asks you to set the minimum RPM. Set the throttle for minimum RPM; for a twin engine boat set both engines to about the same minimum RPM.
10-3-2 Managing fuel consumption curves Record several curves for different conditions. Renaming a curve Press one or more times until the Setup menu is displayed, then select Fuel. Select Fuel consumption curve. Select Name , press name of the curve to rename. Select Rename and press name and press 10-3-3 Using fuel consumption curves...
11 Tides display The tides display is available on C-MAP charts. The tides display shows tide information at a tide station for the selected date.

There are no user serviceable parts. Specialized methods and testing equipment are required B-1 General Problems 1-1 The Explorer 538/538i won’t turn on: The Explorer 538/538i is designed to operate on a 12 volt battery system, where the voltage may vary from 10 to 16 volts. If an excessive voltage is supplied, a fuse will be tripped, turning the display unit off.
Page 59
B-2 GPS navigation problems 2-1 No GPS fix or long time to get fix at startup: May occur occasionally if the antenna does not have a clear view of the sky. The satellite positions are constantly changing. Antenna cable not connected to display unit. Restart the GPS (see section 14-3).
Page 60
B-3 Fuel consumption problems Note: For the Explorer 538/538i to measure fuel consumption, the optional fuel flow kit must be fitted. 3-1 Fuel used or remaining seem inaccurate: Explorer is not wired for auto power (see section 15-4). In rough seas, fuel may surge back and forth through the fuel transducer, resulting in incorrect readings.
