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.
iii
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.

Heading and Position Data
Full functionality of the radar/chartplotter 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 8.
Providing Heading Data for Radar/Chart Overlay and MARPA
The performance of MARPA and Radar/Chart Overlay 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 and Radar/Chart Overlay.
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.
In multiple-display systems, heading must be connected, via NMEA, to each
display that will be used for MARPA.
DISPLAY key as
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 E. If you are using a suitable
third party heading sensor, refer to its documentation for installation and
calibration details.
Chapter 1: Overview 1-7
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.

The Chartplotter
Display
Display
The SL70MRC or SL70CRC display includes a Chartplotter. The chartplotter
includes a small-scale world map and detailed navigation information is
displayed when a cartographic chart card is installed. The details displayed
depend on the chart zoom level selected. A plotter mode is provided to enable
route plotting and tracking at large scales even when a chart card is not
installed, or when the chart is zoomed beyond the available cartographic
detail. A typical chartplotter screen is shown in Figure 1-3.
The chartplotter uses position information from a GPS, DGPS, WAAS or
Loran-C instrument. Once the position fix has been established, your vessel’s
position, if on screen, is shown as a boat shape pointing in the direction of the
current heading (or COG if heading data is not available). If no heading or
COG data is available, the vessel is shown as a circle.
The chartplotter screen includes a status bar that displays chart scale, with
either cursor position, range and bearing or, when the cursor is homed to the
vessel (by pressing
Course Over Ground (COG) and fix type (VES POS, DIF FIX or SD FIX).
The status bar also indicates if radar/chart overlay is switched on.
FIND SHIP), vessel position, Speed Over Ground (SOG),
Any waypoints you have placed are displayed (unless you turned them off in
Chart Set Up as described in Chapter 7) and the current route is shown.
Information can be viewed on-screen by positioning the cursor over a
waypoint, current route or chart object. The chartplotter screen can also show
additional information, depending on your currently selected options, set up
selections and data available from other equipment.
An example chart display, in its default configuration, with a chart card
installed, is shown in the following illustration.
Several functions are available to control the display as follows:
• Zoom in/out and Pan the Display
• Offset the Chart or Center the Chart around the Vessel
• Synchronize the Chart and Radar (if radar data is available)
Operation of these functions is described in Chapter 2.
Chartplotter Display Options
In addition to the display set up options previously described, chart set up
options, described in Chapter 7, allow you to customize the chart by selecting:
• What cartographic features and level of detail are displayed.
• Chart orientation (north up, head up or course up), datums and position offset.
• How waypoints are displayed (symbols and numbers).
• Vectors for heading, COG and tide.
