INTENDED USE

The display units detailed in this handbook may form part of navigational radar systems intended for light marine use. These displays and radar systems are only an aid to navigation.

SAFETY NOTICES

This radar equipment must be installed and operated in accordance with the instructions contained in this manual. Failure to do so can result in personal injury and/or navigational inaccuracies. In particular:

1.HIGH VOLTAGE. The LCD display unit and scanner unit contain high voltages. Adjustments require specialized service procedures and tools only available to qualified service technicians – there are no user serviceable parts or adjustments. The operator should never remove the display unit cover or attempt to service the equipment.

2.ELECTROMAGNETIC ENERGY. The radar scanner transmits electromagnetic energy. It is important that the radar is turned off whenever personnel are required to come close to the scanner to perform work on the scanner assembly or associated equipment.

It is recommended that the radar scanner is mounted out of range of personnel (above head height).

Avoid looking directly at the antenna as your eyes are the most sensitive part of the body to electromagnetic energy.

When properly installed and operated, the use of this radar will conform to the requirements of ANSI/IEEE C95.1-1992 Standard for Safety Levels with Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3Hz to 300 GHz and NRPB, Board Statement on Restrictions on Human Exposure to Static and Time Varying Electromagnetic Fields and Radiation. Doc NRPB, N0. 5 (1993).

4. NAVIGATION AID. This unit is only an aid to navigation. Its accuracy can be affected by many factors, including equipment failure or defects, environmental conditions, and improper handling or use. It is the user’s responsibility to exercise common prudence and navigational judgements. This radar unit should not be relied upon as a substitute for such prudence and judgement.

Set Up Options

Set up options allow you to choose what is displayed, how it is displayed (including language and units), bearing mode and how the display operates with other equipment. You can view the cursor position and a variety of data from other equipment, e.g. speed, heading, depth, wind and tide information in a set of user-selectable data boxes.

Display options are provided in System Set Up, described in Chapter 5. Screen Presentation Options, described in Chapter 2 allow you to switch the cursor and data boxes On/Off. The cursor box and user-selected data boxes can be moved around the screen.

Operating Modes

You can view a full screen radar.You can also set Windows On to split the display into two half-screen windows to show supplementary data. The main operating mode (radar) is displayed in the upper window; you choose what is displayed in the lower window.

The following are available:

Table 1-1:	Operating Modes and Window Options
Display		Full-screen mode	Half-screen Window Options
SL70C, SL70M PLUS		Radar	CDI, BDI or Nav Data

Half-Screen Window Options

•Radar display: Data can be displayed full screen or in a half-screen window.

•CDI: This gives the Course Deviation Indicator graphical display, with data relating to the target waypoint.

•BDI: This gives the Bearing and Distance Indicator graphical display, with data relating to the target waypoint.

•Nav Data: This shows nine (mono display) or sixteen (colour display) data boxes, providing navigational data in the units specified in your set up. Note that up to 6 of these data boxes are also available as a user-selectable group (see Section 5.3).

You select the operating mode and windows using the DISPLAY key as described in Chapter 2.

Chapter 1: Overview	1-5

Heading and Position Data

Full functionality of the radar is achieved when it is part of an integrated system with other equipment connected via SeaTalk or NMEA 0183. Data from this equipment including position and heading is shown on the display and is used in calculations.

Details on connecting other equipment are given in Chapter 6.

Providing Heading Data for MARPA

The performance of MARPA is dependent on the quality of your heading sensor. It is important that both the heading sensor and the radar scanner (bearing alignment) are correctly calibrated. Refer to the appropriate heading sensor and radar scanner handbooks for calibration details. The better the accuracy of your heading data, the better the performance of MARPA.

A gyro compass provides the best performance in all conditions. Alternatively you could use a fluxgate compass with rate gyro stabilization.

MARPA requires heading data to be frequently updated (we recommend a data output rate of greater than 8 Hz); heading data must therefore be provided to the display on NMEA.

We recommend the Pathfinder Smart Heading System (which includes the Gyro Plus 2 unit). Good results are also obtained with a Raymarine autopilot system incorporating a 150G or 400G Course Computer with internal rate gyro.

Other heading sensors connected on NMEA may provide satisfactory results in reasonable sea states. However, in unsettled conditions a rate gyro compass is advisable.

Contact Raymarine Customer Services or your authorized Raymarine dealer for additional information. For specific configuration details with the Raymarine course computer refer to Appendix C. If you are using a suitable third party heading sensor, refer to its documentation for installation and calibration details.

1.2 The Pathfinder Radar PLUS Display

When a scanner is connected and the radar is in Transmit mode, the radar picture provides a map-like representation of the area in which the radar is operating. Typically, your ship’s position is at the centre of the display, and its dead ahead bearing is indicated by a vertical heading line, known as the Ship’s Heading Marker (SHM).

The radar picture can be viewed with a variety of fixed or customised range scales. On color displays, the color of the radar returns (echoes) indicates their intensity: the strongest returns are shown in yellow and the weaker are shown in shades of blue. A status bar at the top of the radar image displays range, current heading and mode indicators for the various options you can set.

An example radar picture is shown on the next page, with example radar returns (echoes) and default Pathfinder Radar information. The Status Bar is also illustrated.

The radar display can show additional information, depending on your currently selected options, set up selections and the data available from other equipment. The example displays on the following pages show some of these features.

Functions are available to control the display as follows:

•Zoom the Display

•Offset your vessel from the centre of the radar picture

Operation of these functions is described in Chapter 2.

Pathfinder Radar PLUS Display Options

In addition to the display set up options previously described, radar set up options allow you to customise the radar image by selecting how radar marks and Electronic Bearing Line (EBL) data are displayed. You can also specify timed transmit mode and custom range scales.

The Screen Presentation Options, described in Chapter 2 allow you to switch range rings on/off and waypoint display on/off.

Note: When you turn the display off and on again, the Screen Presentation settings are retained in memory.

Dedicated Keys

The dedicated keys: DISPLAY, MARKS, GAIN, VRM/EBL, MULTI, ALARMS, RANGE, ENTER, CLEAR, MENU and POWER have fixed functions; the functions are similar on all Pathfinder displays. For example, ALARMS is used to set up the system alarms on both a chartplotter and a radar.

Some keys can be used in two ways:

•Press: Press the key momentarily and then release it. This method is used for most key operations.

•Press and hold: Press the key and hold it down for the length of time stated (for example, 3 seconds), and then release it.

When you press a dedicated key, one of the following happens:

i.The associated operation is actioned, e.g. change chart scale (RANGE).

ii.A pop-up menu is displayed, providing further options.

iii.A set of soft keys is displayed, providing further functions.

As you press a key, a single audio beep confirms the key action. If the keypress is not valid for the current screen or mode, three rapid beeps sound to indicate that no response is available. If required, you can turn the key beeps off as part of your set up procedure (see Chapter 5).

Soft Keys

Dedicated Keys

The four keys below the screen are called soft keys because their functions change according to the operation. The soft keys are grouped into related sets and subsets providing access to the various functions. The soft key labels are

displayed on the screen just above the keys. The default soft keys are displayed until you press a key, or select an item on the screen; the soft keys associated with the action are then displayed.

The currently selected soft key option is shown by its gray or green background. If the key text is displayed in gray rather than in black, it is not currently available.

When you press a soft key one of the following happens:

i.The associated operation is actioned, e.g. NORTH UP.

ii.A sub-set of soft keys is displayed, providing further functions.

iii.A pop-up menu is displayed, providing further options.

As with dedicated keys, when you press a soft key a single audio beep confirms the key action. If the key-press is not valid for the current screen or mode, three rapid beeps sound to indicate that no response is available. If required, you can turn the key beeps off as part of your set up procedure (see

Chapter 5).

Pop-Up Menus

Pop-up menus usually provide set up options. When a pop-up menu is onscreen, a set of associated soft keys is also displayed as shown in Figure 1-4.

You use the trackpad to select an option from the menu, then use the appropriate soft key to set the option. For example, you can toggle the OFF TRACK ALARM on/off.

Chapter 2: Getting Started & Adjusting the

Display

2.1 Introduction

This chapter provides information and instructions to get you started using your display. It will help you to become familiar with the display and the functions of the controls before you start using the unit. More detailed information on operating the radar display is provided in Chapter 3 and

Chapter 4.

Conventions Used

Throughout this handbook, the dedicated (labelled) keys are shown in bold capitals; for example, MENU. The soft key functions, menu names and options are shown in normal capitals; for example, SCREEN.

Operating procedures, which may consist of a single key-press or a sequence of numbered steps, are indicated by a symbol in the margin.

When the procedure requires you to press a soft key, the soft key icon is shown in the margin.

Simulator

The display unit includes a simulator function, that allows you to practice operating your radar without data from the scanner or GPS system. You will need to use the set up options to switch the display to simulator mode, as described in Section 2.2. You can use it in either of two ways:

•Before the display unit has been installed on your vessel. In this case, you only need to connect the display to a 12V or 24V DC power supply, connecting the red core from the power lead to positive (+) and the black core to negative (-). See Chapter 6 for full details.

•After the display has been installed on your vessel, but while in the marina or at anchor.

The following section, Section 2.2, includes instructions to view simulated radar images.

2.2 Switching the Display On and Off

This section explains how to switch the radar display and scanner on and off, and how to switch the scanner between Transmit, Standby and Scanner Off mode.

You normally operate your radar in transmit mode, but you can use the display unit without the scanner operating as follows:

Standby mode: You should use this mode when you are not operating the radar for short time periods. The scanner does not transmit and the antenna does not rotate, so the radar uses less power. However, the scanner remains powered so when you return to transmit mode, the magnetron does not need to warm up.

Scanner off mode: You should use this mode when you do not require the radar, but you are using the display unit say, to view data from another source. Scanner off mode removes power from the scanner.

To switch the display on, press and hold the POWER key until the unit beeps. The keys light up, the display shows the Pathfinder graphic, followed by the start-up information illustrated below, and the radar starts the magnetron warm-up sequence.

WARMING UP

Figure 2-1: Switching on the Radar Display

After 70 seconds, when the magnetron warm-up sequence is complete, the Standby screen is displayed, with the text STANDBY and a prompt to press the POWER key to enter Transmit mode.

Chapter 2: Getting Started & Adjusting the Display	2-3

To switch the radar scanner from Stand-by mode to Transmit mode, press the

POWER key.

The scanner transmits pulsed energy while it rotates, and the antenna sweep

builds up the radar picture using echoes returned from targets. Displaythe Offand

SwitchingOn

Figure 2-2: Radar Transmit Mode

You can switch on and adjust the display backlighting and, on the mono display, contrast, as described later in this chapter.

To switch to Stand-by mode, press the POWER key.

The display returns to the Stand-by screen, and the scanner transmission and rotation stops.

To use Scanner off mode:

1.Ensure that the radar is in Standby mode, warming up, or displaying a message that radar data is not available.

2.Press the CLEAR key. The message STANDBY. RADAR DATA NOT AVAILABLE appears in the radar picture. The scanner is powered down and the timer, if running, is cleared.

To return to radar operation, press the POWER key. The warm-up countdown is displayed and the radar goes into Standby mode. You press POWER again to switch to Transmit mode when required.
