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.

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.
Data

Heading and Position
Heading and Position
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.

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

Introduction
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
• After the display has been installed on your vessel, but while in the marina

2.2 Switching the Display On and Off
This section explains how to switch the radar display and scanner on and off,
Switching the Display
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

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.

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

The scanner transmits pulsed energy while it rotates, and the antenna sweep
builds up the radar picture using echoes returned from targets.
