CR40/42/50 MKII Introduction and safety summary Chapter 1

1.1 Introduction and system familiarization

Congratulations on your purchase of SIMRAD CR40/42/50 MKII DGPS ChartRadar - a combination of the latest GPS receiver technology and built-in

differential receiver for accurate positioning and prepared for SDGPS, plus: detailed cartography and high performance radar; all in a unique slim-line design with a 10” TFT (CR40), a 10” ATFT (CR42), or 14” TFT (CR50) large LCD display in color.

The CR40/42/50 MKII chart system includes a built-in world chart for rough planning and overview. The choice of chart system best suitable for the CR40/42/50 MKII was carefully singled out to be the C-MAP NT mini cards. The optional C-MAP charts are available world-wide at your local Simrad dealer.

The radar system with dual EBL and VRM markers, direct Quick-range keys, off-center mode, etc. together with Dual Radar feature … two radar displays in one screen, one for short range and one for long distance observations.

The Global Positioning System is at this time and age the most common system used for navigation and positioning all over the world. Not only for maritime use, but also for land-based applications and aviation. The satellitebased system has been developed and is operated by the US Department of Defense in order to provide an accurate and reliable service, which include a 24hour global coverage. The GPS system consists of approx. 24 satellites which orbit around the Earth at an altitude of approx. 20,200 km. The satellites transmit perfectly synchronized data. However, depending on the position, the signals will reach the receiver at a slightly different time. By adding the measured time difference to the known position of the satellites it is possible to calculate the ship’s position to within a few meters.

DS40/42/50 Dual Station - remote control unit for the CR40/42/50 is available in 10” black & white or TFT/ATFT color, or in 14” TFT color.

How to use this manual? The manual is written for the products: CR40, CR42 and CR50, which all share the same type of software. From hereon, these models are referred to as: CRXX. It is a good idea if you make yourself familiar with the key functions, menu structure and rotation of pages (screens) described in chapter 2 before you start out, and then proceed with section 2.7 Initial start-up.

1.2 Safety summar y

Precaution The operating unit should not be exposed to direct sunlight, as

“boiling” the display may cause too high temperatures internally and subsequently damage parts of the unit beyond repair.

Quality service personnel The CRXX is sealed and does not contain any user serviceable parts. Opening of the unit will void its warranty. Touching electrical parts inside may cause bodily harm or death. If the unit is not working properly, please check section 9.12 Troubleshooting. If your CRXX requires servicing or repair, call your authorized SIMRAD dealer.

Power source, fuse and power cable Check that the DC power supplied to the unit is within the range of 10 to 32 volts. Note that the appropriate fuse must be employed (see the fuse rating in section 9.13 Specifications. Ensure that the power cord is firmly attached.

Grounding To reduce electrical interference and risk of electrical shock, properly ground the unit to the ship’s ground using the ground screw on the back of the unit. Good grounding should be exercised for connected equipment, refer to the installation & service section.

2.1 Fundamentals of the PAGE and WINdow system

The CRXX DGPS ChartRadar has a multi-function screen data presentation system. You can choose to have a full screen, or a screen divided into e.g. a chart display and two data/chart displays, etc. The display which is currently activated is indicated by a highlighted frame around the active window. There are five screen combinations to choose from:

WINdow 0

1. Full (1/1) screen. 2. Four ¼ displays. 3. Two ½ displays.

4. & 5. Combination displays of one ½ and two ¼ displays shown together in the same screen.

) Not all displays are available in any size window.

Page 8

CR40/42/50 MKII Fundamentals & initial start-up Chapter 2

As many as 4 screen combinations or full screens can be saved in 4 pages (layers).

Press the

[PAGE] key to toggle between the 4

pages, or hold the [

PAGE] key depressed for

two seconds to start a rotation of the 4 pages. Press [

PAGE]

again to return to manual

operation.

To mix and match the various chart and data displays you wish to have in the PAGE and WINdows presentation, you will first need to know what is pre-set from the factory:

PAGE

Scroll through the four pre-set pages to see if you wish to exchange any of the displays with a different one.

Example of how to edit a pre-set page:

window

We pretend that in this page, window 2 contains the navigation display (highway), window 3 a chart display in a large scale for overview, and window 5 a chart display in a smaller scale to enlarge a

certain area. You now wish to insert the Position display in window 3 instead of the chart display. This is the procedure:

WIN

Press the

[WIN]

key until the frame around window 3 is highlighted

Call up the menu bar, and…

2,1

then call up the POS menu and select “Position”

- you will now have the Position display in window 3 instead of the chart display.

Example of how to edit a full screen to four ¼ displays:

We pretend that you are looking at a full screen which you wish to divide into four ¼ displays. This is the procedure:

First call up the menu bar, and…

then call up the POS menu - see example next page.

Page 9

CR40/42/50 MKII Fundamentals & initial start-up Chapter 2

POSITION

WIN

_2_

POS _1_ Position _2_ Set & drift

_3_ Speed diagram, etc. …

What you do now will determine which WINdow the display you are about to select will appear in.

Press the

[WIN]

key repeatedly to scroll

through the window system.

WIN

Press the

[WIN]

key once to select WINdow 1

-which is the left top quarter of the screen.

Select the Position display

- you will now have the position display presented in window 1. The rest of the windows in this page i.e. window 2, 3 and 4 will contain the displays which were pre-set from the factory. They can all be exchanged with new displays at your choice.

) However, the same display can not appear twice on the same page, so in case you are trying to select the same display in a second window, this is what will happen:

As per above example, you have selected the Position display in window 1, but it may just happen that the Position display was pre-set to window 2 – therefore window 2 will now show the legend: “ Select display via MENU.”

You may select the same display to appear on different pages, but not on the same page.

) An exception is the radar display, which only can appear in ½ window or full screen, and you can only have the radar display appear in one page at a time. You can not toggle from page to page and see different radar displays.

To obtain a “cleaner” view of the chart details, you can turn some of the settings OFF if they do not contribute to the clarity of the chart area you wish to explore. All the listed objects that can be turned on and off speaks for themselves – they are either “shown on the chart” or “not shown on the chart”.

Chart settings

Chart can be set to

NORMAL, COMPRESSED and CHART OFF:

NORMAL

- will show the normal amount of details in the selected chart

scale.

COMPRESSED - will ordinarily provide more details in the same scale. CHART OFF

- will only show all the user-made data such as waypoints,

routes, lines and tracks, etc.

Landfilling can be ON or OFF. When OFF there will be no special color to indicate where the land on the chart is (if any) i.e. land will be all blue.

Boundary lines will indicate available C-MAP chart areas.

Chart area can be set to

LARGE, MEDIUMorSMALL:

LARGE

– Opens a large chart area for pan and scroll. Chart re-draw

time is standard.

MEDIUM

– Opens a medium-size chart area for pan and scroll.

Chart re-draw time is faster than standard.

HEAD UP

– The chart will automatically turn, so your actual course (COG) is up. If a compass is connected, the reference will automatically change to heading (compass).

NAV UP

– The chart will automatically turn, so your bearing to desti-

nation is up. ) To enable chart rotation, the chart cursor must be turned off [CLR].

locked to the center of the screen and the chart will move.

Rotation resolution can be set to adjust the chart for each 5, 10, 15, 20 or 25° changes in present course or heading.

Depth – Level 1, 2 and 3 are identified by different colors. The number of meters in the levels can be changed. The colors are preset in the Palette setup, section 8.2.6.

Grid the LAT/LON grid can be set AUTO/ON/OFF. The color of the grid is preset in the Palette setup, section 8.2.6.

Show scale ON will add a small line to the chart display indicating that the length of the line equals a certain number of nautical miles/km.

Auto chart select When sailing with “Auto chart select” ON and cursor turned OFF, the scale will automatically change to the chart which is available. But when set to OFF, then the selected scale will remain, also when sailing “out of the chart”.

Extended level range ON will provide a higher level of chart details when zooming in and out of scales.

The rest of the objects in the chart setup, from Non active waypoints and down to the last line Target names can all be: ON = shown on chart or OFF = not shown on chart, or AS SELECTED = which means that the choice of having a certain route shown on the display can be made via the menu e.g.

With DGPS receiver built-in or connected: dGPS= differential data received. DGPS= corrected differential data received.

Status indicator and accuracy

Small letters (a,b,c,) indicate that SA is active, and the position accuracy is expected to be better than 100 meters in 95% of the time. Capital letters indicate that SA is OFF, and the position accuracy is then expected to be 15 meters or better in 95% of the time. dGPS indicates that differential data is received, either via built-in differential receiver or from external receiver. And DGPS indicates that the position is corrected by the differential data. The accuracy will typically be 3-5 meters.

In order to utilize the high accuracy of the GPS system, it is necessary to align the lat/long calculations to the paper charts you are using. RefertoPositionsetupdisplayonnextpage. ) When using C-MAP electronic charts, the datum will be aligned automatically.

The value of HDOP (horizontal dilution of precision) expresses “the quality” of the satellite geometry in relation to 2D positioning and a fixed antenna altitude.

PDOP (position dilution of precision) is equivalent to 3D positioning. The values will typically stay between 1.3 and 8. The lower the value the higher the “quality”. A poor geometry might produce a value of more than 20.

If the preset DOP limit is exceeded (indicated by * in the position display) it will cause the position updating to stop until it once again is within the limit.

The DOP limit can be changed manually, but should not be set to higher than 8 (factory set-up), as this may result in poor accuracy – false position.

Status – can either be:

LOCKED = locked on a beacon and receiving differential data

NOT LOCKED =

not locked on a beacon and receiving no differential

data.

NOT INSTALLED = there is no built-in DGPS module in unit. NOT IN USE

= external DGPS receiver applied.

Beacon is monitored –

YES

it should be safe to rely on the received differential data, because the beacon station’s performance is under observation. If

, then you have to use the received differential data with caution,

as there is no guarantee it is not faulty.

Frequency – the frequency of the beacon station can be set manually if known. However, when left in

AUTO

the navigator will always search

for the nearest station with a good signal strength.

Bit rate – indicates bits per second, and can be set manually to 25, 50, 100 or 200 bps.

Signal strength – a good signal strength is 20 and up.

Signal to noise ratio (SNR) – should be 8dB and up.

Message – type 16 message will be displayed when received from the

DGPS system. The contents of this message could be something to do with the performance of the system. Temporarily out of service, etc.

5.8 Data transfer via DataCard or disc

Data transfer to and from external memory can be performed via DataCard,orwithaSimradTL50TurboLoader:viaanordinary

1.44Mb disc.

DataCards and TL50 Turbo Loader are optional equipment available from you local Simrad dealer. How to perform data transfers via TL50 Turbo Loader (inclusive data from Shipmate RS2500 Trackplotter) is described in the TL50 manual.

Use the Simrad DataCard or TL50 Turbo Loader to make backup files of all the user data you have created plus the current setups in the internal memory of the unit. Do it whenever you have added important data, or when you wish to transfer routes and waypoints, etc. to another compatible unit. The storage capacity of the DataCard/TL50 disc is divided into two databanks of each 450 Kb, meaning that the entire internal memory can be stored in one databank.

• External memory with data transfer via DataCard:

Call up the menu bar, and…

3,9

load the ‘Data transfer’ window

Select the drawer where you have inserted the DataCard i.e. [1] for the

Page 63

Save on DataCard

Press [3] to call up a new INFO window where you can see which data will be transferred i.e. how many routes, waypoints, etc. and how much space it will take up in bytes + percentage of max. storage capacity. Choose which databank you wish to transfer the data to (use the +/zoom keys). The actual date and time will be saved with the data transfer. A name can be added for easy identification later on.

ENT

Press [ENT] to activate ‘Save on DataCard’

) You will now receive a warning that existing data on the DataCard, in the databank you have chosen, will be overwritten. You can not ‘add more information’ to data already transferred. Whenever transferring data either from an XX40/42/50 MKII to Databank 1 or 2 on DataCard, or from Databank 1 or 2 on DataCard to an XX40/42/50 MKII, the data package will replace the entire capacity in the receiving unit, except when a TL50 Turbo Loader is connected to the unit, then you can decide how much data you want to transfer - refer to TL50 manual.

7. Radar operation

The CRXX combines chart plotting with radar navigation. For first time users of Radar, we have included a basic description of the radar presentation with a basic understanding of how the controls affect the radar’s operation and display.

The following paragraphs describe the control settings used for initial display setup, turn-on procedure, inclement weather operation and finally the turn off procedure. Radar controls are described in chapter

7.2.

7.1 Radar map

The radar picture appearing on the display is a map-like representation of the area in which the radar is operating. Typically, the ship’s position is at the center of the display. The operator may reposition or offset the ship’s position up to 66% of the radius anywhere on the screen. The ship’s dead ahead bearing is indicated by the heading line flashing at the 0° relative bearing with every revolution of the sweep trace (Head-Up mode).

Coastline contours and landmass are generally depicted in solid filled yellow (DAY) or green (NIGHT) echo areas. Other surface vessels, and channel buoys, are displayed as smaller single “pips” or echoes. The radar picture or map can be viewed in many different sizes or scales from own ship. These sizes are selected by the range scale controls. Greater detail of radar echoes nearby own ship is shown when the short or nearby range scales are selected. The best technique for assessing the radar presentation characteristics is to start with using a longer range scale and then switching to shorter ranges when nearby targets appear, or as the ship approaches the coastline, harbor, or other vessels in the area.

The long range scales (i.e. 3, 6, 12, 24nm) best show the overview of the ship’s relationship to landmasses, weather fronts, and large ship targets at or beyond view.

Page 82

CR4042/50 MKII Radar operation Chapter 7

7.1.1 Map orientation

In the RELATIVE mode, the heading line always appears on the screen at 0° relative according to the on-screen bearing scale, and is coincident with the antenna beam passing the ship’s bow. Thus the top of the displayed picture represents the direction in which the ship is heading.

All targets appearing on the display are “Relative” to own ship’s position and heading. As you look outside at targets around you, you will see that the targets are appearing on the Radar display at the same relative bearing.

The Electronic Bearing Lines (EBL) are available radar tools used to measure bearings to radar targets from own ship. The bearing readouts maybeinrelativeortruemodes.

7.1.2 Environmental effects

The effects of weather and water surface conditions generally act to reduce the ability of radar to detect targets. Weather effects reduce the long range at which targets can be detected. Water surface clutter (waves) reduces the ability to detect targets close by. Either can obscure the echoes from targets that may prove dangerous to your vessel.

You can’tseewind on your radar screen, however you can see its effects when it produces waves and spray on the water surface. “Sea Return” is most pronounced in the direction from which the wind is blowing. Proper use of your “Sea clutter” (also known as STC) adjustment can reduce the effect of wind and waves, but care must be taken not to increase the control to the point where weak targets will be overlooked.

Rain, hail and snow can return echoes that appear on your radar screen as a blurred or cluttered area. Targets within the area of precipitation can be masked by the clutter. The maximum range of the radar pulse is greatly reduced as the energy of the radar beam is scattered and absorbed by the water droplets. Proper use of your Rain Clutter (also known as FTC) adjustment helps you to look into areas of precipitation to detect targets.

Page 83

CR4042/50 MKII Radar operation Chapter 7

Buoys are moored to the bottom with concrete via chain. The chain is longer than the depth of the water to allow the buoys to ride in the current and go up and down with the tide. Unfortunately this allows the buoys to lean in the direction of the current. Radar reflectors built into the buoy do not work well when the side of the buoy is pointed to the sky. Therefore if you are going with the current, the images of the channel markers may appear faint. If you are going against the current, the buoys will be leaning in your direction and produce a stronger image on the radar screen.

The iron mass and angles of the metal in the structure of a bridge can cause unpredictable interference patterns on your radar. It is not unusual for a reflected image to appear on the radar screen in front of you just as you pass under the bridge. A similar effect is also common on sailboats where the radar antenna is mounted close to an aluminum mast.

Overhead cable crossings can mimic a moving target on your radar screen. The cable target usually appears to be on a collision course. The entire length of cable does not appear on the screen, only a point on the cable, and that point keeps changing giving the illusion of a moving target.

7.1.3 Effects of ship’s movement

Radar images can be drawn in two ways on the radar display to show the ship’s motion. The type of display modes are called “Relative motion” and “True motion”. In Relative motion, the most common radar display mode, own ship is permanently fixed at the center of the display but radar echoes (targets) move in relation to your vessel. With no movement of the ship, a steady display of fixed radar echoes is shown. If the ship is moving ahead on a constant course, echoes appearing at the top of the display will move downward across the display. Your own ship’s position will always remain at the center of the display.

If the vessel alters course to the right, the displayed echoes will be displaced by an equal amount in bearing in a counterclockwise direction, and vice versa. These changes in the display pattern with ship movement is an extremely important characteristic to remember

Page 84

CR4042/50 MKII Radar operation Chapter 7

when maneuvering around nearby vessels, or buoys. The True motion display mode can be compared to your vessel moving on a map or chart. In True motion mode, the surrounding landmass echoes remain stationary on the screen and if your ship is moving at a constant course and speed, you will see your position move across the screen towards the edge of the display. Any other targets which are underway will also be moving on the display screen at their True course and True speed. All motion seen on the True motion display is “TRUE” (meaning motion over the ground).

7.1.4 Navigational echoes

Echoes displayed on the radar screen may be large or small, bright or faint, depending on the size and shape of the object and its angle relative to your radar antenna. The radar indication is not always the same as an observer’s visual indication; a nearby small object may appear to be the same size as a distant large object on the radar. With experience, however, different targets can be identified by the relative size, brightness, and position of their radar echo returns.

Buoys and small boats are one example of targets that are sometimes difficult to distinguish from each other. Their movement in the waves do not present a consistent reflecting surface. Consequently, their echoes have a tendency to fade and brighten or sometimes to disappear momentarily. Although buoys and small boats often resemble each other, usually the motion of one target identifies the boat from the buoy.

High coastlines and mountainous coastal regions are often observed at the longest ranges of the radar. However, the first sight of landfill on the radar’s longest ranges may be a mountain several miles inland from the coastline and not the actual coastline. The coastline may not appear on the radar until the vessel has approached land nearer the line of sight distance.

7.1.5 Sea return

Not all radar echoes are produced by hard navigation items such as boats, buoys and land. Some radar echoes may be received from irregularities on the surface of the water, particularly at close range by

Page 85

CR4042/50 MKII Radar operation Chapter 7

breaking wavecrests, particularly in windy weather and in heavy seas. These echoes appear on the radar screen on the very short range scales as multiple small echoes next to own ship. Under high winds and extreme conditions the echoes from sea clutter may appear as dense background of clutter forming the shape of an almost solid disc, as far as one to three miles in all directions from own ship. The radar has a control which can be used to minimize the effects of sea clutter pickup on the screen.

7.1.6 Storm and rain squall returns

The radar can also see echoes from rain or snow. Echoes from storm areas and rain squalls consist of countless small echoes, continuously changing in size, intensity, and position. These returns sometimes appear as large hazy areas on the display depending on the intensity of the rainfall or snow in the storm cell. The cells usually may be visible at long distances due to their high altitude above the radar horizon and are very helpful for observing potential bad weather conditions. If the returns from storm areas and rain squalls are not desired, the RAIN clutter control can be adjusted to minimize the effect on the radar screen.

7.1.7 Blind sectors or shadow effect

Funnels and masts, (when located near the antenna array) may cause shadows. Shadow areas can be recognized since beyond the obstruction there will be a reduction of targets and noise intensity, although not necessarily a complete cutoff seen on the screen. However, if the shadow angle is more than a few degrees, there will be a blind sector.

In some shadow sectors the beam intensity may not be sufficient to obtain an echo from a very small object even at close range, despite the fact that a large vessel can be detected at a much greater range. For this reason, the angular width and relative bearing of any shadow sector should be determined at installation. Sometimes shadowing can be seen on the screen by increasing the radar gain until noise is present. Darker sectors indicate possible shadowed areas. This information should be posted near the display unit, and operators must be alert for objects in these blind sectors.

Page 86

CR4042/50 MKII Radar operation Chapter 7

7.1.8 Side lobes

Echoes on the radar screen are not always the direct returns to the radar antenna. There are many types of false echoes that can appear on the display if certain conditions occur. The sections that follow, briefly describe the echo patterns that may be produced by these false echoes and their likely cause. It should be noted that the radar operator, through observation, practice, and experience usually can detect these conditions very quickly.

A very small part of the RF (Radio Frequency) energy from each transmitted pulse is radiated outside the radar’s narrow beam, producing side lobe patterns. Side lobes normally have no effect from distant or small surface objects, but the echo from a large object at short range may produce an arc pattern on the radar screen similar to a range ring, or appear as a series of echoes forming a broken arc. Side lobe echoes normally occur at a range below 3 miles and usually can be reduced by adjustment of the SEA clutter control.

7.1.9 Radar interference

Whenever two or more radar equipped vessels are operating within reception range of each other, mutual interference is likely when the radars are operating near the same frequencies. This interference usually appears on the screen as a series of small dots. The interference seems to move from the PPI center (radar screen), sometimes in a straight line, but more often in a long, sweeping curve. This type of interference is more noticeable on longer range scales. This does not, as a rule, impair the effectiveness of the radar as a navigational aid. Since the interference can be completely eliminated by turning IR “ON” in the function menu. The IR feature is normally left “on”.

7.1.10 False echoes

Occasionally, echoes may appear on the screen at positions where there is no actual target. This type of target is called a False Echo. Sometimes they are known as Ghost Images, Indirect Echoes or Multiple Echoes depending on how they are generated.

Ghost images usually have the appearance of true echoes, but, in general, they are intermittent and poorly defined. A true ghost image retains

Page 87

CR4042/50 MKII Radar operation Chapter 7

a fixed relationship with respect to the true image and characteristically produces a more arc-like appearance with a tendency to smear on the screen. Ghost images are sometimes caused by large targets which have a wide, smooth surface as they pass by near your own ship. Ghost images sometimes are referred to as indirect echoes. Indirect echoes may appear when there is a large target, such as a passing ship at a short range, or a reflecting surface, such as a funnel or spotlight on your own ship in line with the antenna. The signal, on first striking the smooth side of the large target, will be reflected, and these subsequent echo returns to the antenna are shown on the display. However, the same reflection may also hit other masts or obstacles and then be picked up by the radar antenna with enough strength to appear as a target on the radar screen at various locations.

Multiple echoes could appear if there is a large target having a wide vertical surface to your own ship at a comparatively short range. The transmitted signal will be reflected back and forth between the wide vertical surface of the target and your own ship.

Thus, multiple echoes will appear beyond the true target’s echo on the same bearing as shown below. This is not a very common phenomena.

True echo

7.2 Starting op eration

The Golden Rule!

Today’s radars are packed full of neat features designed to make your cruising more enjoyable and safer. Use these features when you can, but remember the old axiom KISS (keep it simple sailor). If a target shows on the display, there most likely is something there. If there are no targets shown on your display, it doesn’t guarantee there are no other objects around. Maintain a good visual watch, proceed at a safe

speed and enjoy your boating.

Scanner type: use +/- keys to select the radar antenna model which is installed. See the Installation manual for selection of antenna. ) Be careful not to select the wrong type of Scanner, as this may cause a system failure.

Scanner rotation: can be set to either 24 or *48 rpm, depending on the scanner type (use +/- keys). *Running 48 rpm is liable to reduce the lifetime of the mechanical parts. ) Do not change the Scanner rotation while the radar is transmitting. Make sure the radar function is either in “Standby” or “Power off”.

Antenna height: enter the actual height above water of the radar antenna/scanner.

Heading adjust: Orientation should be HU (Head Up). Turn the ship, so a target becomes visible in the front and adjust until target is straight ahead on the heading line. Use the +/- keys to position it correctly.

Tuning reference: is preset to 079. Normally there should be no need to adjust the Tuning reference. However, if sensitivity is poor or there are any symptoms at all suggesting improper tuning, you may need to make an adjustment: Choose a displayed range of 3nm or higher. Use cursor to go to the Tuning reference value. Use +/- keys to adjust the value until echoes are clearly visible.

Zero range/timing: Most common settings are between 105 and 115. Default setting is: 109. To adjust: Press the [9] key to set the displayed range to 0.125nm. Use cursor to highlight “Sea” and with +/- keys set the sea clutter very low, so you can see the transmitting pulse. Now adjust the value for Zero range so the ring around the ship is very small. If you have knowledge of the distance to a nearby object, say a mast or a buoy, you can verify if the Zero range is set correctly by measuring

Page 91

CR4042/50 MKII Radar operation Chapter 7

the distance. To do so, place the VRM ring on top of the object and check the readout in the control panel (follow procedure in sec. 7.2.5). If the readout is not the same as the known distance, adjust the value in Zero range with 1 figure up/down for every 3 meter adjustment.

Sensitivity is preset to 048. Adjust value if echoes are not reasonable clear i.e. the higher the value, the less detailed presentation of echoes.

Auto sea and Auto gain settings i.e. Minimum, Default, Maximum. If necessary, the factory presets can be adjusted (0 to 255) to improve the clarity of the echoes. After the adjustment, the new values will be the new AUTO settings. Preset parameters can only be adjusted from X-MIT mode after correct scanner type, etc. has been selected and Stretch mode is left in off position:

• Auto gain values

To adjust the preset values, you first have to:

1. Adjust Rain to minimum acceptable value: move cursor to the ‘Rain’ bar, and adjust with +/- keys.

2. Adjust Sea to minimum acceptable value: move cursor to the ‘Sea’ bar, and adjust with +/- keys.

3. Set ‘Tune’ bar to ‘AUTO’ mode: move cursor to the ‘Tune’ bar and press [CLR].

4. Choose a displayed range of 3nm (press key [4]) or higher.

Now you are ready to adjust the Auto Gain values in the last three lines of the Radar setup display: Auto gain minimum (factory value 080): Adjust to optimum radar image - fairly clear targets and no noise.* Auto gain default (factory value 090): Adjust to best picture.* Auto gain maximum (factory value 105): Adjust to maximum allowable level of noise.* *) wait for screen to update to see the result of adjustment.

7.2.3 Start transmission

Normally when starting the transmission, it will take approx. two minutes for the antenna to warm up and be ready for transmission. For initial start-up and after long storage, see below.

Make sure nobody is standing close to the radar antenna when it starts to rotate after the transmission is activated!

up the antenna

However: ) Starting up the first time after installation or after long storage (6 months), the antenna will need an extra 20 minutes to warm up, so when the count-down of 120 seconds are finished, the radar must be left in Standby mode for the extra 20 minutes it takes for the antenna warm up properly. This way you will contribute to the lifetime of the magnetron in the radar antenna.

Orientation can be either: HU, NU or TM

HU (Head-Up in relative motion): The heading line always appears on the display at 0 degrees as the antenna passes the bow of the vessel. Targets appearing on the display are relative to your own ship’sposition and heading. Most people will operate the radar in Head-up mode, as it allows for the easiest interpretation of the situation around your boat.

NU (North-Upintruemotion):Inthismode,targetsaredisplayedat their measured distances in true direction from your boat. North being at the top of the display. In the NU mode, you must be interfaced with an electronic compass for proper operation. Receiving the alarm: “Heading missing” the system will change to Head-Up in relative motion.

TM (True Motion): Targets are displayed at their measured distances in true direction from your boat. Own ship moves past land, buoys and fixedobjects.IntheTMmode,youmustbeinterfacedwithan electronic compass for proper operation.

Sea – see Glossary + section 7.1.8 and 7.2.2. Press [CLR] to toggle between manual and auto operation.

Rain – see also Glossary and section 7.2.2.

- adjusting for Rain clutter: Rain clutter or FTC (Fast Time Constant)

removes the leading edge of the returning signal. Rain or snow returns cause many small echoes, continually changing in size and position to appear as a hazy area on the display. Rain and snow targets do not have much depth. By removing the leading edge, the unwanted echoes will disappear leaving real targets visible. The amount of delay is controlled by the rain clutter adjustment. As you increase the adjustment, the delay will get larger causing the returning signals to decrease, or disappear. Do not adjust the rain clutter too high, as this will eliminate all small targets.

) To properly adjust for rain clutter:

1. Set rain clutter to the OFF position.

2. Set gain.

3. Slowly increase rain clutter until the hazy area caused by the rain or snow become less dense. Increasing it too much will not only remove the rain clutter, but also any targets inside the rain area. Note! Since Rain and Snow are continually changing in size and density, tweaking of the rain clutter adjustment is necessary to maintain the best results.

Stretch – toggle between OFF, Auto, Pulse and Video. Auto: the radar system will choose the optimum solution. Pulse: will select the nearest longer pulse length on the screen, so the

weaker targets far away will be enlarged.

Video: all targets will be enlarged.

EBL (Electronic Bearing Line) mode: In this mode a dashed line can

be rotated counter-clockwise or clockwise by means of the zoom keys. The bearing from the boat to the target can be displayed in True or Relative degrees. Reset figures with

[CLR].

VRM (Variable Range Marker) mode: This is an option that allows to increase or decrease a circular dashed line by means of the zoom keys. The control panel at the side or below the radar display, will indicate the distance in nautical miles that the dashed line is from the boat. By placing the dashed line over a target or over an object, it will indicate the distance to same. The readout automatically adjusts for the range the radar is on. This dashed line can be placed over either a moving target, such as another boat, or a fixed target, such as land. The VRM feature should only be active when needed, and otherwise turned off

[CLR] to eliminate extra clutter on the radar screen.

Trails after targets – toggle between OFF, 30sec, 1min, 2min, 5min, 10min, 15min, 30min, PERM (permanent). See also Glossary.
