Service and repair

In case of a 6000i operating problem, you can contact your dealer or return the 6000i to the factory for diagnosis and repair. When calling, be sure to have your 6000is serial number and software revision available. In describing a problem, be as
complete and accurate as possible. Before returning the 6000i for repair, you may want to save your waypoints and routes. If the unit is properly networked to another 6000i display, a copy of your waypoints and routes is already saved in the other unit. You can also transfer data to a Northstar 900 series navigator or to a PC as described on pages 80 and 83. NOTE:
To prevent delays, its critical that you rst obtain a Return Materials Authorization (RMA) number from our Service Department before returning your 6000i.
Shipments to Northstar should be made to the following address: Northstar Service Department 30 Sudbury Road Acton, MA 01720 If you have special overnight or second-day shipping requirements, please call for turnaround time and freight costs before you ship your 6000i.
Northstar 6000i Quickstart Guide
This section gives an overview of each of the 6000is major functions and the basic information you need to begin using them. We suggest you read this section carefully as you first use the 6000i, and then refer to the following Reference Sections, as necessary, to answer any questions you may have.
Quickstart Guide Revision D
Turning the 6000i on and off

CAUTION!

Use caution when navigating with electronic charts. Although every effort has been made to ensure that the data the 6000i uses is as close as possible to paper charts, errors and omissions are inevitable. The captain is responsible for cross-checking the 6000i against other sources of navigation data.

Turning the 6000i on

To turn the 6000i on, gently and briefly press the PWR key. (See Figure 1 on page 10 for a picture of the controls.) The 6000i beeps and displays its start-up screen, and then performs a series of self-tests to check its critical components and functions. Next, a message warns against relying on the 6000is chart cartography as the only means of safe navigation. Acknowledge the warning message by pressing the CHART key.
Now youre ready to get underway with your 6000i!
If this 6000i was recently used at or near its present location, it will usually be ready to navigate within one minute after it is turned on.

Turning the 6000i off

To turn the 6000i off, press and hold the PWR key for a few seconds until the screen goes dark.

3. Press a menu key to select the rst chart region. 4. Wait until the ashing CHART LOAD alert turns off (about 20 or 30 seconds). 5. Repeat steps 2, 3, and 4 for all remaining regions. The Northstar 6000i will now be able to access the cartridge data rapidly.

Additional information

Large scale charts typically do not contain spot soundings, depth contours and shaded depth areas. In smaller scale charts, the data source may omit contours and shaded areas deeper than 10 meters (33 feet). Areas not present in the data source are shown as very light blue. Gold Charts contain much additional information about navaids and various types of obstructions. When a navaid or obstruction is selected by placing the cursor on top if it, this information may be displayed by pressing the More info menu key. An additional info bar is displayed below the chart, showing the text associated with the object. In some cases, there is more text than can be displayed in a single info bar. Press More info additional times to display any remaining text, and then turn the info bar off.

First use of a cartridge

The first time a new Gold Chart cartridge is used, the 6000i reads the cartridge data and indexes it for faster access. We strongly recommend performing the following procedure once for each new Gold Chart cartridge: 1. Insert the cartridge. 2. Press the CHART key (twice, if necessary) to display the Chart Region screen.
Gold chart display, with a light selected
Changing the track control
The 6000i displays your track history as a series of dots indicating the path youve recently traveled. You can choose how often to store a position fix as a point in your track history. The 6000i stores up to 4,096 position fixes. When it reaches this limit, the 6000i starts erasing the oldest points to make room for your new points. The more often you mark your track, the faster you fill up the track memory. The maximum track length depends on how often points are stored. You can choose among the following options for point storage, and the corresponding track length:
every 1 second every 2 seconds every 4 seconds every 8 seconds
for 60 minutes total for 120 minutes total for 4 hours total for 8 hours total
every 20 seconds for 20 hours total every 40 seconds for 40 hours total every 1 minute every 2 minutes
for 60 hours total for 120 hours total
- or FREEZE TRACK (stops the storage of additional points, keeping the track unchanged)
To clear the entire track history, press Erase Track and ENTER. To remove the track display from the
CHART screen while the 6000i continues to

To display the TRACK CONTROL screen, press Track control on the CHART SETUP/STATUS screen.

Returning to GPS navigation
To return to using GPS signals for navigation, repeat the steps shown for selecting
loran in Selecting and displaying loran, on page 47, but choose GPS instead of loran.

Using Phantom Loran

If you have lists of fishing spots and other waypoints that you recorded as loran time differences (TDs), but you no longer have a loran receiver, the 6000i can automatically convert its GPS coordinates into TDsin real time, as you travel. You can display your current position as TDs or navigate to waypoints using TDs. The accuracy from this conversion is generally 500 to 1500 feet. This feature, called Phantom Loran, can help your transition from loran to GPS. You can use the 6000i to simulate the full operation of a loran receiver, using all of the 6000is navigation functions as if it were actually receiving loran signals. These calculated TDs wont exactly match the positions of previously recorded TDs obtained directly from actual loran signals. In most areas, TD errors shouldnt exceed one microsecond. However, larger errors are possible in areas with poor station geometry, or for which the 6000i doesnt have accurate, factory-programmed ASF correction points.

Selecting Phantom Loran

To display position coordinates as Phantom Loran TDs: 1. Press the STAR key to display the OPTIONS/SERVICE INFO screen. 2. Press Navigation Options, then highlight the NAVIGATION SOURCE option. 3. Press Edit, then press the cursor pad to select PHANTOM LRN. 4. Press ENTER, then press Return. 5. Press POSITION to display the LORAN POSITION screen.
Setting the Phantom Loran GRI
Press Set GRI to change the GRI to be used in calculating the displayed TDs. Press the cursor pad to display the available GRIs one at a time. When the GRI is correct, press ENTER.

waypoint is a specific point you designate either by entering its coordinates or by pointing to it on the chart using the cursor. Hundreds of waypoints can be stored in the 6000is memory, and can be strung together to form a variety of routes.

Introducing waypoints

To store a route, see page 71.
A waypoint is a point (a location) that youve entered into the 6000is memory. The waypoint is displayed on the chart with the symbol youve chosen. In contrast, the term nav aid refers to a point thats permanently stored on the Navionics chart cartridge. Here are some of the functions you can perform with waypoints:
go to a point on the CHART screen in one step (making a quick waypoint)

store waypoints into the 6000i go to these waypoints string these waypoints together to form routes edit or erase waypoints or routes plot waypoints on a chart transfer waypoints and routes from the 6000i to a PC or an older Northstar navigator, and back again

Designating a waypoint

You can designate waypoints in any of the following ways:
use the cursor on the CHART screen to select an existing waypoint or create a new waypoint enter numeric position coordinates select an existing waypoint from a list
Designating a waypoint on the chart screen
You can go to a waypoint by moving the cursor to that point on the chart either selecting an existing waypoint on the CHART screen, or designating any other location on the CHART screen: 1. On the CHART screen, move the cursor pad to choose an existing waypoint or nav aid, or any unmarked chart position. 2. Press Go to waypt. (If you didnt choose a waypoint, the key will read Go to cursor or Go to navaid.) 3. Press ENTER.
You can also string together several waypoints to form a route, and let the 6000i guide you from one waypoint to the next (see Introducing routes, on page 71).
Reference section 3 Navigating to Waypoints
If you selected an existing waypoint, the 6000i begins guiding you directly to it. If you chose a new cursor location, the 6000i makes a new waypoint named -QUIK-, and guides you directly to it. Repeating this same procedure will create a new -QUIK- waypoint that overwrites the existing one; therefore, you may want to save the -QUIK- waypoint as a regular waypoint by renaming it. See Editing waypoints, starting on page 70.
2. If necessary, select the type of coordinates you want to enter by pressing the Coord type menu key:
lat/lon distance and bearing from here (your present position), or from any waypoint stored in the 6000i loran TDs (make sure the GRI displayed is correct, and change it if necessary)
Entering a waypoints position coordinates
You can use the keypad to enter waypoint coordinates, and then go to that waypoint: 1. Press WAYPTS/ROUTES, then press Quick waypoint to display the QUICK WAYPOINT screen.
3. Use the keypad to enter the waypoints coordinates.
The initial position shown is your latest x. If you wish, you can now give the -QUIKwaypoint a unique name after youve entered its coordinates, since the next -QUIK- waypoint you make will overwrite this one: Just move the cursor to the name eld and change the name from -QUIK- to a unique permanent name before continuing.

To enter waypoints on a CHART screen: 1. Press WAYPTS/ROUTES. 2. Press Waypoints. If necessary, press Next view to display the WAYPOINTS CHART screen.
4. Press Add waypt to capture the cursor coordinates and display the NEW WAYPOINT screen. 5. Now follow the instructions above for entering a waypoint numerically, starting with Step 4. The coordinates of the cursor (Step 6) will be already entered dont change them unless you mean to.

Waypoints chart screen

3. Press the cursor pad to move the cursor to the position of the new waypoint. You can zoom in or out, as necessary, to precisely place your waypoint.
Creating avoidance-area waypoints
You can make avoidance areas from new or existing waypoints. Then, if you travel into a designated avoidance area, the 6000i will sound a beep and flash an alarm on the screen. The 6000i displays an avoidance area on the CHART screen as a waypoint surrounded by a circle. The circle is the avoidance areas warning radius, which you set when you create or edit the waypoint. You can use the international slashed circle no-entry symbol as the avoidance points symbol to help you quickly see it on the chart.
The waypoint is treated as an avoidance point only if you specify a warning radius larger than zero. In other words, just assigning the slashed circle symbol to a waypoint doesnt cause the 6000i to treat that waypoint as an avoidance point.
to respond by turning or stopping after you hear the alarm, and to allow for the typical accuracy of the navigation source in use.
Setting the avoidance-area alarm
The 6000i will sound an audio alarm when you enter an avoidance area, provided youve turned on the audio alarm. (See Alarm audio on page 142.)
The avoidance alarm is only an extra safety feature to help alert you to possible hazards. It doesnt replace local knowledge, proper use of charts, the person on watch, or any other aspects of good seamanship that are required to safely navigate.
To make any waypoint act as an avoidance point, enter a number in the WARN RADIUS box at the bottom of the NEW WAYPOINT OR EDIT WAYPOINT screen. The warning radius can be from 0.1nm to 4.99 nm. Be sure to allow a little extra distance around the hazard area so youll have time Reference section 4 Creating waypoints and routes

Editing waypoints

You can change any information about an existing waypoint (except for the type of coordinates used to save it) or erase it entirely by using the 6000is waypoint editing function. 3. To edit the waypoint, press Edit. (On the WAYPOINTS CHART screen, the key is labelled Edit waypt.)

Changing waypoints

To change a waypoints name, description, position coordinates, or warning radius: 1. Press WAYPTS/ROUTES, then Waypoints. If necessary, press Next view to display the waypoint screen you want. 2. Select the waypoint by highlighting it with the cursor pad.

Saving a route as you travel
To make a record of a trip that you may want to repeat later, you can save waypoints into a route as you travel by pressing the SAVE/MOB key every time you pass a point you want to store in the route. The save-route function makes this a very simple process: First, you tell the 6000i that you want to save a route as you travel, then you press SAVE/MOB as you pass each new waypoint, then you tell it to stop saving the route when you reach the end of the route. To begin saving a route as you travel: 1. Press WAYPTS/ROUTES, and then press Routes to display the ROUTES screen:
