EMC Installation & Service Guidelines

IMPORTANT NOTE

All JRC equipment and accessories are designed to the highest industry standards for use in a marine environment. Their design and manufacture conforms to the appropriate Electro Magnetic Compatibility (EMC) standards, but good installation is required to ensure that performance is not compromised. Although every effort has been taken to ensure that the equipment will perform under all conditions, it is important to understand what factors could affect operation of the product. Complete installation instructions are provided in SECTION 2 of this manual. Some preliminary suggestions are made below.

Installation

To avoid the risk of operating problems, all JRC equipment and cables connected to it should be:

•At least 1m (3 feet) from any equipment transmitting or cables carrying radio signals e.g. VHF radios, cables and antennas. In the case of SSB radios the distance should be increased to 2m (7 ft).

•More than 2 m (7 ft) from the path of a radar beam. A radar beam can normally assume to spread 20 degrees above and below the radiating element.

•The equipment should be supplied from a different battery than the one used for engine start. Voltage drops below 10.2V in the power supply to our products can cause the equipment to reset. This will not damage the equipment, but will cause some loss of information and this can also change the operating mode.

•Genuine JRC Cables should be used at all times. Cutting and rejoining these cables can compromise EMC performance and should therefore be avoided unless doing so is suggested in the installation manual.

Check Before Going to Sea

•Always check the installation before going to sea to make sure that it is not affected by radio transmissions, engine starting, low battery voltage, or other problems.

•In some, installations, it may not be possible to prevent the equipment from being affected by external influences. In general this will not damage the equipment but it can lead to it resetting, or momentarily may result in faulty operation. This can then be avoided by turning off the RADAR 1800 prior to starting the boat engines for instance.

5

Servicing and Safety

•JRC equipment should be serviced only by authorized JRC service engineers. They will ensure that service procedures and replacement parts used will not affect performance. There are no user serviceable parts in any JRC product.

•Some products generate high voltages, and so never handle the cables/connectors when power is being supplied to the equipment.

•Always report any EMC related problem to your nearest JRC dealer. We will use any such information to improve our quality standards.

Suppression Ferrites

The following illustration shows the range of suppression ferrites fitted to JRC equipment.

Notes for Suppression Ferrite Installation

Connections to other equipment

If your JRC equipment is going to be connected to other equipment using a cable not supplied by JRC, a suppression ferrite MUST always be fitted to the cable close to the JRC unit.

Introduction

Function

Congratulations on selecting the JRC RADAR 1800 Color LCD system to assist your navigation.

Whether you purchased this radar because of its compactness, power economy, ease of installation, or long term reliability, one thing is certain;the moment you turn on your RADAR 1800 Display you will know that you are seeing a revolutionary new concept in Radar technology.

You are the proud owner of a radar system unmatched in the marine recreational industry.

Radar signals are shown on a color LCD display with excellent graphic clarity and detail.

A single glance at your Display will give you a complete and accurate 360˚ radar picture of other vessels, buoys and land surrounding your vessel.

By connecting with JRC’s GPS/DGPS sensor, the LCD Display allows you to continuously display latitude, longitude, scale division and track line of the vessel in color.

Since the color of the vessel track line can be displayed in any color and deleted when required, it can be checked at a glance.

In addition to track line, waypoints and transit point(convenient for marking dangerous location, shoals and fishing spots) can be stored and diplayed in color.

The distance and bearing from the ever-changing current position to a waypoint is displayed automatically.

Since displayed sea areas can be magnified, reduced or moved as desired, it can be used for a number of application.

System components

The Color Radar plotter RADAR 1800 consists of a compact display unit connected to scanner unit.

Use of the GPS capabilities requires the optional GPS 112:JRC's GPS sensor. Use of the DGPS capabilities requires the optional DGPS212:JRC's DGPS sensor.

Features

Easy To Operate Features

Like the JRC RADAR 1000 and RADAR 1500, the JoyStick and Jog Dial are mounted to provide easy to operate for everyone.

Scan Correlation Feature

The Scan Correlation signal processing function, normally only available in larger commercial radars, is included to provide an enhanced presentation of targets especially in high sea return conditions (false random targets caused by radar signals bouncing back from waves).

Automatic STC Feature

In addition to manual STC adjustment, an Automatic STC setting is also available to help adjust out annoying sea return targets.

Inter Switch Feature

With the optional Inter Switch Kit (NQE-1200), the antenna can be controlled by either one of the two display units installed at the cabin fly bridge, etc. (No simultaneous control by the two units)

Connectable with the JRC GPS Compass

By connecting with the JLR-10 JRC GPS Compass, you can select the heading mode between Head-Up, North-Up, and Course-Up.

Various Navigation Screen Feature

By connecting an optional GPS or DGPS sensor, such information as the position or course of your ship can be displayed on the screen.

By registering WAYPOINT and ROUTE PLAN, it is also possible to display such important information as the distance or bearing to/of a WAYPOINT that ensures safe and economical navigation.

This information can be displayed in the chart plot style, in the intuitive illustration style, or in the numerical style depending on your selection.

Console Mounting/ Surface Mounting

ATTENTION

Make sure there are no hidden electrical wires or other items behind the desired location before proceeding. Also check that you have free access for mounting and cabling.

1)Select a mounting location: a clear, flat area of at least 8”(203mm) wide by 8” high, having 5.5”(140mm) depth behind the panel. At that time, make sure that there are no hidden electrical wires or other items behind your selected location before proceeding.

2)Tape the mounting template from the console mounting instruction over your selected location on the panel and trace around the edges.

3)Drill a 1/2”(12.7mm) pilot hole at the top and bottom of the cut-out area.

4)Cut along the outside edge of the cut-out line with an appropriate saw.

5)Drill holes, using a 1/5”(5mm) drill bit, for the four threaded screws, 2 on each side, on the mounting template.

6)Remove the yoke, two knobs, two spacers and two damping rubbers from the unit, then securely attach the threaded screws to the rear cabinet and verify that the unit will fit inside the cut-out area.

7)Complete installation of the DC power, Scanner, GPS, NMEA and ground wiring into the console and make the connections onto the rear of the unit.

8)Place the unit into the cut-out and fit the washers, lock-washers, onto the threaded screws behind the mounting console, and tighten the nut to hold the unit in place.

Installing the GPS/DGPS Sensor

Selecting the Position for Installation

CAUTION

When connecting the cable attached to the equipment, do not bend to an acute angle, twist, or impart excessive force. Doing so may damage the cable and cause a fire or an electric shock.

Do not install the equipment in a place with excessive vibration. Doing so may cause the equipment to drop or tip over resulting in injury or defects.

ATTENTION

Install the equipment in a place without any obstacle, in order to ensure that GPS signals can be

directly received from satellites without interference or reflection of signals from surrounding objects. If possible, select a place having the following characteristics.

1An open space that allows uniform reception of satellite signals.

2Far away from any of high power transmission antennas.

3Outside the radar beam range.

4Away from the Inmarsat antenna by not less than 5 meters and below the level of its antenna.

5Away from the antenna of a VHF, MF/HF transmitter and a direction finder by not less than 5 meters.

6Away from Magnet Compass by not less than 1 meter.

If it is difficult to find an ideal site, select a place temporarily and install the equipment. Conduct a test to make sure that the proper performance can be obtained and then fix the equipment in position. If it is installed at an improper place, reception may become intermittent, resulting in shorter position fixing time and poorer position accuracy.
