INTRODUCTION
1.O General Congratulations on selecting Raytheons NAV 398 for Loran-C/GPS navigation aboard your vessel. We are sure you will enjoy using this ultra modern, full function, and compact navigation system. The NAV 398, with its large STN LCD display, excellant graphics, on-sceen prompts, and oversized soft silicon keys, provide simple operations to guide you through the various navigation functions. From the moment you turn on the NAV 398, you will be surprised at how easy it can be to use this Loran-C or GPS Navigator. The NAV 398 is a feature-packed Navigator that operates with inputs from the Raynav 508 or 508A Loran-C sensors, or with the Raystar 108 8-Channel GPS sensor, or with both sensors together. One key press gives you quick access to either navigation system. The NAV unit includes storage for up to 500 waypoints and 10 route plans in the NAV units internal memories. The[m[ key stores your present position as a waypoint instantly with a single key press. The[E[(ManOverboard) key not only stores an instant position with one key press, but activates a special display to steer you back to the MOB location. A special Dynamic CD1 display provides a 3-D effect for steering to destinations in the route; even showing turns in the route and waypoints along the way.
1.1 About This Manual The purpose of this manual is to provide you with the most important information for obtaining the best operation and performance from your NAV unit. Please take the necessary time to read the various sections.
In the event that you are using a Loran-C Navigator for the first time, please refer to the Raynav 508/508~ Loran-C Sensor instruction manual for basic loran information. The Introduction section of the 508 manual includes a listing of common Loran C Terminology used with loran. If your NAV398 is using the RAYSTAR 108 GPS Sensor, the Raystar 108 instruction manual includes a general description of the GPS system which may also be helpful. The Raystar 108 GPS sensor is compatible with Raytheons Differential Beacon Receiver. If you have added the DGPS Receiver to your system, a simple explanation of the US Coast Guards DGPS system is included in that manual for your reference.

When SeaTalk data is used, the NAV unit provides: magnetic variation, COG, Cross-Track error, Lat./Long, GPS status data (including HDOP, fix status), SOG, waypoint #, bearing, and distance, Arrival alarm, and MOB signals to the SeaTalk bus. External navigation equipment requiring NMEA 0183 data inputs normally obtain their required data via connection to the NAV 398 data output ( yellow & green ) wires. However, some users may wish to operate the GPS (or Loran) sensor unit directly with other navigational equipment capable of

accepting position data in the NMEA format. Please refer to the Raystar 108 or Raynav 508/508A instruction manuals for details on making this type of interconnection. Data Input One feature of the NAV398 is to transfer the waypoint and route memory contents of the internal memory to external computer files and to re-load the memory from the computer. Downloading of files occurs through the Data Output connections (Green and Yellow wires). To Upload files into the NAV unit the Data Input wires of the power cable assembly should be used. Make connections as follows: DATAIN + = WHITE DATA IN - = BROWN The data Input must be in the NMEA format using the WPL and RTE sentences. 2.3.4 Ground Connection One important need in any installation is to obtain the cleanest, noise-free signals possible, for measuring and calculating your position. Part of this requirement can be met by assuring a proper connection from your NAV unit to the ships ground system. The ground system provides both a completion of the signal path for the sensor and a drain for noise sources. There are two separate wires labeled GROUND in the cable assembly. Both the WHITE and BROWN wires should be connected to the nearest connection point of the ships Rl? ground system. Normally, on a steel hull boat, a good clean connection to the ships hull makes a sufficient ground. On Fiberglas or wood hull vessels, connection to a ground plate or to the engine block or other bonded groundwork should provide acceptable grounding.

OPERATION
3.1 General This chapter provides instructions for the operation of your new NAV 398 LCD NAVigator unit. We think you will find the operation of the NAV 398 to be easy and straightforward. The approach to take in becoming familiar with its operation is one of relaxed confidence. The unit is quite user friendly and relies on screen prompting to guide you through the operations and set-up menus. As you progress through the operating section, take time to practice each function of your NAV398. Study the illustrations and repeat operations, if necessary, until you have become comfortable and confident. Time spent in becoming familiar with the unit will strengthen your knowledge, confidence, and skill in using this full-featured NAVigator where it counts.afloat. Thank you for selecting one of Raytheons fine NAVigation products. Great care and effort has been put into providing you with a useful, attractive _ design. We are sure it will provide many years of valuable NAVigation data and trouble free operation. 3.2 The Keyboard The NAV 398 is designed for simple operation, but if you should ever become confused over which display you are on or, if you get lost while performing various operations or entries,usually pressing the -1 key return you to the Position display will always or the familiar Main menu. One other item to remember about the keyboard is that a valid or correct key press is confirmed by a single audio beep tone, while if an invalid or wrong key is pressed, a series of multiple beeps will be heard. If this happens, just check the screen again and pick the proper key operation.

The Signal Status screen provides a readout or the progress made by the sensors in acquisition and tracking of the signals. Once full signal lock-on has been achieved, the screen switches to the Position display, the Auto Startup sequence is completed, and normal operation is underway. 3.3.4 Selecting Loran/GPS Mode One key feature of the NAV 3% is that the unit can be either a loran or GPS depending on the type of sensor that is connected,.or both, if a sensor for each system is attached. Normally, if only one sensor is used, the unit detects the type of sensor and automatically puts the NAV unit into the correct system mode during the Auto Start-up program. If both the RayNAV 508/A Loran-C and Raystar 108 GPS sensors are connected,.each system will always be operating and normally tracking signals and either system can provide your position and NAVigation data instantly. TheI-key is used to toggle the unit between the two system sensors. The systems can be changed anytime you are on the PMtion, NAVigation, CDI, or PLOT modes. When the GPS mode is selected, GPS characters become illuminated along the bottom left edge of the LCD display and the latitude/longitude position and ships course and speed data is then GPS derived.

If the Differential Beacon Receiver is connected and tracking the beacon signal DGPS is indicated in the message window. The latitude/longitude readouts will include the differential corrections for greater accuracy. When the Loran-C mode is selected, the LORAN characters will be illuminated along in the message window of the display and the L/L position and ships course and speed data is then Loran-C derived. When both GPS and Loran sensors are connected, the NAV unit always selects the sensor that was last used when the power is turned ON. If its the very first time the unit is used and both sensors are connected, the GPS is always selected as the priority system. 3.4 Initializing Sensors Although the R~YNAV 508 Loran and Raystar 108 GPS sensors are capable of finding the latitude/longitude position once they have been powered up, at the very first power-up following installation or after a Master Reset, the position finding process may take up to 30 minutes or more. This startup time can be reduced to some degree by entering initialization information into the sensors memory. The process for initializing each sensor appears in the following paragraphs. The very first time the NAV unit is operated, or following a Master reset of the unit, the screen will prompt you to enter your estimated latitude coordinate followed by entry of the estimated longitude coordinate., Once youve entered this information into the sensors via the NAV 398, the sensors should be able to find your location more rapidly. The loran sensor only needs the initial L/L input and should typically lock-in in 3 to 5 minutes. The GPS sensor also needs the initial L/L input and prefers to have the Date and Time and Antenna height information as well for quick acquisition and tracking.

The Event message will appear and show the saved memory #. l GO TO a Destination.Press the wi key. Enter the waypoint # using three digits and then press(ENTET\1.
3.5.7.1 Saving Events You can save your present position for future use as a waypoint when you are in any of display modes. The EVENT data will be stored sequentially into the next available waypoint memory just like a normal waypoint. Just press theI- key. o m p t a p p e a r s t o p e r m i t y o u t o message pr A select any other memory # location. If no keys are pressed in live seconds, the message will show the Event memory number and then disappear. If during the 5 second period you type in a different memory number and press thdmlkey, the Event will be saved into the memory that you have designated. If the memory number you typed was the same number as your current destination, upon pressing the(ENTERl[key the screen alerts you by showing "DEST PT" flashing. If you typed the memory number by mistake and really dont want to overwrite your destination point, just press the -Ikey. If you DO want to update the current destination coordinates,

OPERATION 3-16

then go ahead and press thelENTER(key. The memory will be updated, and the screen returns back to the last POS, NAV, CDI, or PLOT display. One caution on saving Events. For maximum accuracy, its best to be sitting next to the desired location and let the readouts settle down for a few seconds before pressing themjkey. If you are flying by a buoy at high speed, the readouts will be displaying a position lagging behind the boat a short distance. The faster you are moving, the greater the lag error will be. Each time you store an event, the coordinates can be remembered as either a loran, GPS, or DGPS position. Since there will be absolute position differences when using the different systems, the NAV 398 memorizes the type of position data (L, G, or DG) recorded for each event and shows the indicator on the screens when the Event is used for a destination waypoint. The indicators L, G, or DG appear immediately after the WPT characters on the screen. In this way, the operator can use the matching systems to return to Event locations more accurately. Its a very good idea to write the Event numbers and location descriptions onto your paper waypoint log for future reference at the first opportunity. 3.5.7.2 GOT0 Destinations After waypoints have been stored into the NAV unit memories, they can then be selected for use as direct destinations. ThemGoTo/31 key permits the operator to quickly select a waypoint destination. The GOT0 mode works this way: Press them] key. Initially, when the-1 key is pressed, the GOT0 WFT -I message appears in the destination window area so you can input the desired destination memory number. The message will show three dashed lines until the first character is entered. Use the numeric keys to type in the desired memory number. Example: Type 1-1, 6 1-1 f o r waypoint n u m b e r 6. When thelENTER(key is pressed, the desired waypoint becomes the destination waypoint. If you are on the NAV or CD1 screens, the display will change the bargraph appearing on the top of the NAV screen and put the boat symbol

3.6 Entering Waypoints

3.6.1 General Waypoint Information One of the key operations of the NAV 398 is to guide you to planned or pre-programmed waypoint destinations from your present position. Waypoints can be entered into your 398 unit by using one of the following four methods: l Storing au Event (instantly saves ships present position as you pass a buoy, enter a channel, or are sitting on top of a great fishing spot). l Direct entry of Latitude/Longitude coordinates taken from marine charts or light list, etc. l Direct entry of Time Difference (TDs) coordinates. These are usually from a chart or a friends loran. l By using Range and Bearing from your present position. The NAV 398 has 500 internal waypoint memories for storing waypoint position coordinates. These memories are numbered from #OOl to 499. Whenever you decide to enter new waypoint position data, or recall old waypoint information, the waypoint memory location number has to be entered first. This is necessary so the NAV unit can place or retrieve the information from the correct memory. Since there are so many waypoint memories, its usually a good idea to make a paper log of your stored waypoint data. The log should include the Name of the waypoint, its Memory #, L/L and TD coordinates, the source of the position data, and may be even the normal bearing and range from your slip. Some owners use certain numeric blocks of the memory locations to store certain waypoint groups that make up trips or route plans. In this way, favorite trips are saved and used over and over again by the number grouping selected. Of course, the paper log book helps keep things straight for everyone. 3.6.2 Waypoint Directory To gain access to the STORE WAY POINT operation, press thelwpT/4 key. The WAYPOINT DIRECTORY appears on the screen. The directory is used exclusively to pick one of the memory locations for storing your

The Satellites Tracked display shows the identification numbers( ID) of the satellites being received, tracked, and used for L/L calculations in the reverse block characters. The Raystar 108 sensor is usually tracking 4-6 satellites at any one time and can track up to eight, if visible. So, seeing 6 to 8 blocks illuminated is not at all unusual. In the column below each Sat ID # you can see see the individual satellites azimuth angle, its elevation angle from the horizon, and signal level (SNR). The data is displayed for all satellites being received. Below the Status box the HDOP number appears and provides the current fix quality. This rates both the strength of the satellite signals as well as the geometry of the satellite positions. Typical HDOP numbers for a good fix are 2 or less. Fair HDOP values are 4 or less; Poor HDOPs are over 5.

t OPERATION 3-40

In the title box, the fix type is displayed at the right end. Here, you will see either 3D or 2D characters. The 2D mode is a two-dimensional position fix mode that will not factor the calculated altitude (antenna height) into the L/L position solution. AUTO mode calculates altitude. Generally, the 2D mode works the best for marine navigation. The Status display also includes readouts of your estimated position, local date and time, and antenna height. There are two softkeys on the GPS Status screen. Thmsoftkey accesses the GPS sensor Initialization sequence. Thm softkey permits special setups that effect the GPS position fixing or readout displays. The next sections cover the GPS initialization sequence. 3.10.2.5 Initializing GPS Sensors The following paragraphs describes the series of initialization inputs to be checked when your NAV unit is to be operated with the RAYSTAR 100 or RAYSTAR 108 GPS Sensors.

Whedwiis pressed, dthe display o n t i n u e w i t h e n t e r i n g is now rea y to c the offset value for TD2. Type in the numeric value 0,2. Press. i s T h time press the +/, softkey, since the correction was a minus value. Then press IENTER]to store the -0.2~s TD2 value.

Manual L/L Corrections

Instead of using the Auto ASF program or the manual TD offset values, the L/L coordinates may be corrected manually. The process is similar to making manual TD correction entries, and is accomplished in the following manner: First go to a fixed navigation point and read your current L/L position from the loran display. Extract the L/L coordinates of the fixed point from your marine chart. Subtract the two Latitudes and the two Longitudes from each other to determine the appropriate correction to be entered into the NAV unit. Example: N42 42.23 Loran W071 24.54 Loran N42 42.08 Chart WO7124.50 Chart -. 15 (South) -.04 (East) After you have calculated your correction, select the POSITION CORR. menu. Press the @ softkey to highlight AL/L. Type in the value of Latitude Offset 1, 2, 6. Press the-1 key. N/S appears at the center softkey position. Since our sample offset is to the South, press them softkey to change the direction for the latitude correction to S.Then press-l. Whenle[is pressed, the display will expect you to enter the value of the Longitude Offset with the numeric keys. Type in 1, 0,5. Press -1 and the E/W characters appear again at the center softkey position. This key to select E (-) for time the correction is to be subtracted. Use the longitude correction before pressing /E Press thd=lkey to return back to the Main Menu Directory. You could presslCLEARlone more time to go back to the display mode. However, this time press the-1 softkey again so we cm check the AVERAGING menu for Loran.
3.10.4.3 Averaging for Loran Gn the LORAN AVERAGING menu we can select averaging periods for the Loran L/L readouts and one for the Speed readouts. Averaging periods of SHORT, MEDIUM, LONG, canbeselected.

SHORT- Shortest averaging, quickest response, slightly erratic readings. MEDIUM-Gives smooth readings with more response. LONG-Longest averaging period. Gives smoothest readings. Generally for Loran , For L/L Short or Medium averaging is recommended. For Speed, Medium or Long is recommended. When correct, presslCLEARpo return to the Main Menu Directory. 3.10.5 NAV Setups - GPS This section covers the NAV SETUP menus that are particular to GPS operation. The COURSE/BEARINGS menu of the NAV SETUPS menu happens to have the same operations for both Loran and GPS. The operations for selecting magnetic bearings were covered in section 3.10.4.1. However, for GPS operations, the POSITION CORR. and AVERAGING menus are unique to GPS and are discussed in the following paragraphs. 3.10.5.1 Position Corrections - GPS In the NAV 398 there are actually three forms of correction available in the GPS mode. They are: l Geodetic datum l Manual L/L correction l Manual TD correction When the GPS sensor converts the ranging measurements from the satellites into Lat/Lon coordinates it uses a mathematical formula (or datum) to arrive at the L/L solution. In preparing charts or maps, cartographers also rely on a particular mathematical formula or geodetic datum (scaling system)on which to calibrate the Latitude/Longitude coordinate structure of the charts. The type of datumused to make the chart is normally listed on the chart in the table area.

T~~BEACONSTATUS A display
is the first screen. The A indicates the receiver is operating in the automatic mode. The frequency of the beacon is displayed. Each beacon operates at an assigned frequency. Usually beacons operating in the same area are assigned different frequencies, so they are easily identified.

The baud rate of the data transmission is displayed. Although the baud rate can range between 50 to 300 baud, most beacons are currently transmitting at 100 baud. The third item on the screen is RSSI. The RSSI is the signal strength of the received signal. If thelJsoftkey is pressed you can set the frequency steps the beacon receiver should use in its search mode. The selections are 1 Khz or 500 Hz steps. Although a few beacons operate at XXX.5 Khz intervals, most beacons operate at XXX Khz. So, setting this to 1Khz will provide a faster search and acquisition of the beacon in AUTO mode.

OPERATION 3-56

When the -1 softkey is pressed the screen changes so you may type in the frequency and baud rate of your desired beacon.

Beacon Transmitter

On this menu you should type the frequency and press thejjkey. Then type in the baud rate and press the -1 key. When the-key is pressed following the baud rate entry, the screen will return to the last used display mode screen. Initially manual tuning to beacons is probably unnecessary. As the DGPS system becomes more developed and beacons are more numerous towards 1996, it is possible that more than one strong beacon signal may be picked up in some areas. Manual tuning assures that only the desired beacon will be received. 3.10.5.3 Averaging for GPS When, in GPS mode, the AVERAGING GPS screen appears, you can see that only one averaging filter is used for both the L/L position readouts and the Speed readouts for the GPS mode. Pressing the softkey changes the averaging selection for readouts between and LONG. When the desired Averaging level is highlighted by the block, press thelCLEAR(key to step back to the Main Menu Directory.

MAINTENANCE

4.1 General Maintaining satisfactory operation of your NAV 398 can depend on how well you care for the equipment. The simple maintenance tips that follow can save you time and money, as well as prevent unnecessary premature failures. Always keep the equipment as clean as possible. Use a soft clean cloth for cleaning the surface filter, control panel, etc. Do not use abrasive cleansers, chemical cleaners or solvents. Use glass cleaners or a suitable general purpose detergent.
Periodically check the system hardware. Inspect antennas and mounts, making sure all components are free of corrosion and mounted securely. Examine all cables for evidence of chafing or abrasions. Make sure connections to the ships DC power and RF ground system are clean and tight. A light coating of a high insulation silicon grease (such as Dow Corning DC-4) on connector pins can protect the plug contacts from corrosion.
4.2 Replacing The Fuse Your NAV 398 has its fuse protection in the power cable assembly. The fuse is a 2 amp fuse and protects the ships DC power line in the event of an over current condition in the NAV 398. A replacement fuse is included with the spare parts Kt supplied with your NAV unit. If the NAV 398 will not turn ON, the fuse should be checked and replaced, if necessary. The fuse is released from the fuse holder by gripping each end of the fuse holder assembly, slightly press the two sections together, and then apply a half twist counter-clockwise to the cap end. After replacing the fuse in the holder re-assemble the fuse holder by applying pressure in the reverse direction.

MAINTENANCE 4-l

4.3 Replacing The Battery Both the NAV 398 and the RAYSTAR 108 GPS sensor units contain internal memories to store your position and other set-up information. A lithium back-up battery keeps this memory information intact even when the units are disconnected from the ships battery. The estimated life span of the internal memory battery is from three to five years. If a battery should fail, the memory contents will be lost. While both the NAV 398 and RAYSTAR 108 GPS sensor can be operated without their batteries, the 298 would not retain its waypoint memory, and the RAYSTAR 108 would require a time consuming cold start-up each time you use the units. This would be extremely inconvenient. To insure troublefree operation, it is recommended that the battery be replaced every three years with an exact replacement lithium battery by your Authorized Raytheon dealer or by the Raytheon Factory Service Center. 4.4 Master Reset The NAV 398 unit is a microprocessor based equipment, and like most computers, it runs smoothly and efficiently in normal use. However, under extremely rare conditions, (for example: during very low and intermittent DC input power conditions, such as while starting engines) the unit could hang up or freeze. If this condition should occur, re-boot the NAV 398 with a Master Reset when the DC power condition has been normalized. There are two types of Master Resets available: l Hard Reset - Clears all waypoint memories and resets the unit to the default settings. l Soft Reset - Only resets the default settings, but does not effect the waypoint memories. Typical Default Settings: Latitude Direction = North Magnetic Variation = On Averaging L/L = Med Display Mode = "NAV 398" Backlighting = Off

Longitude Direction = West Position Corrections = Off Units = NMiKTS Arrival Alarm = 0.10 nm Other Alarms = 0.00 nm
