SAFETY INSTRUCTIONS

DANGER

Before turning on the radar, make sure that there is no one near the scanner unit.

Serious injury or even death may result if a rotating antenna strikes someone standing nearby.

WARNING

Radio Frequency Radiation Hazard

The radar antenna emits electromagnetic radio frequency (RF) energy which can be harmful, particularly to your eyes. Never look directly into the antenna aperture from a close distance while the radar is in operation or expose yourself to the transmitting antenna at a close distance.

WARNING

ELECTRICAL SHOCK HAZARD

Do not open the equipment.

Only qualified personnel should work inside the equipment.

Turn off the radar power switch before servicing the scanner unit. Post a warning sign near the switch indicating it should not be turned on while the scanner unit is being serviced.

Prevent the potential risk of being struck by the rotating scanner and exposure to RF radiation hazard.

Wear a safety belt and hard hat when working on the scanner unit.

Serious injury or death can result if someone falls from the radar scanner mast.

Do not disassemble or modify the equipment.

Do not place liquid-filled containers on the top of the equipment.

Fire or electrical shock can result if a liquid spills into the equipment.

Do not operate the equipment with wet hands.

Electrical shock can result.

Keep heater away from equipment.

Heat can alter equipment shape and melt the power cord, which can cause fire or electrical shock.

CAUTION

Do not use the equipment for other than its intended purpose.

Use of the equipment as a stepping stool, for example, can result in personal injury or equipment damage.

Fire, electrical shock or serious injury can result.

Turn off the power immediately if water leaks into the equipment or the equipment is emitting smoke or fire.

Continued use of the equipment can cause fire or electrical shock.

No one navigation device should ever be solely replied upon for the navigation of a vessel.

Always confirm position against all available aids to navigation, for safety of vessel and crew.

ARPA Safety Instructions

WARNING

No one navigational aid should be relied upon for the safety of vessel and crew. The navigator has the responsibility to check all aids available to confirm position. Electronic aids are not a substitute for basic navigational principles and common sense.

• This auto plotter automatically tracks an automatically or manually acquired radar target and calculates its course and speed, indicating them by a vector. Since the data generated by the auto plotter are based on what radar targets are selected, the radar must always be optimally tuned for use with the auto plotter, to ensure required targets will not be lost or unwanted targets such as sea returns and noise will not be acquired and tracked.

• A target does not always mean a land mass, reef, ships or other surface vessels but can imply returns from sea surface and clutter. As the level of clutter changes with environment, the operator should properly adjust the A/C SEA, A/C RAIN and GAIN controls to be sure target echoes are not eliminated from the radar screen.

CAUTION

The plotting accuracy and response of this auto plotter meets IMO standards. Tracking accuracy is affected by the following:

• Tracking accuracy is affected by course change. One to two minutes is required to restore vectors to full accuracy after an abrupt course change. (The actual amount depends on gyrocompass specifications.)

• The amount of tracking delay is inversely proportional to the relative speed of the target. Delay is on the order of 15—30 seconds for high relative speed; 30—60 seconds for low relative speed.

Display accuracy is affected by the following:

• Echo intensity

• Radar transmission pulsewidth

• Radar bearing error

• Gyrocompass error

• Course change (own ship or target)

iii

Models

This series of radar and ARPA is available in the following models: Model

Freq Band Output Transceiver configuration FR-2115,FR-2115-B X-band 12 kW TR-up FR-2125, FR-2125-B X-band 25 kW TR-up FR-2125W, FR-2125W-B X-band 25 kW TR-down FR-2155, FR-2155-B X-band 50 kW TR-up FR-2135S, FR-2135S-B S-band 30 kW TR-up FR-2135SW, FR-2135SW-B S-band 30 kW TR-down FR-2165DS S-band 60 kW TR-up

Note: FR-2155, FR-2155-B, FR-2165DS are not IMO type-approved models.

All comes with the EPA (Electronic Plotting Aid) standard fitted. An optional ARP-26 board is available to provide the full functionality of ARPA (Automatic Radar Plotting Aid). Also with an optional Video Plotter RP-26 board.

Besides the choice of the above models, the FR-2105/2105-B Series is available in the Regular type (R-type) and IMO type. The IMO type is designed as a primary radar under the 1974 SOLAS Convention on ships below 10,000 GT and also as a high speed craft radar when fitted with ARPA function (at least ATA by IEC 60936-2). The R-type satisfies the IMO and IEC standards but includes more flexibility of functionality to meet the fishing boats particularly (thus, this is an expanded type in other word).

The table below shows the differences between R-type and IMO type radars. Other functions and specifications are common. The operator cannot navigate between these two types. Your radar is factory set for IMO type. If you want an R-type, please ask your service representative.

Precautions for high speed targets

! Assume your ship is making 40 kt and a target ship is approaching at 40 kt right toward you.

Then the relative speed is 80 kt. With the antenna revolving at 42 rpm, the target blip appears jumping to a new location 59 m nearer. This jump corresponds to 19 mm on the 300 mm display using the 0.25 nm range scale. On such a short range you may lose the track of target in the midst of sea clutter, random noise or other targets. Use one step larger range scale.

! ARPA can fail to track a target when the relative speed exceeds 100 kt.

Chapter 1 OPERATION

DANGERDANGER

Before turning on the radar, make sure that there is no one near the antenna unit.

Serious injury or even death may result if a rotating antenna strikes someone standing nearby.

Power switch

Control head

1.1 Turning on the Power

The POWER switch is located at the left corner of the control head. Push it to switch on the radar system. To turn off the radar, push it again. The screen shows the bearing scale and digital timer in approximately 15 seconds after power-on. The minutes of warm-up time. During this period the magnetron, i.e., transmitter tube, is warmed for transmission. When the timer has reached 0:00, the indication STBY appears indicating that the radar is now ready to transmit pulses.

In warm-up and standby condition, you will see the message BRG SIG MISSING. This is normal because a bearing (azimuth) signal is not yet generated when the antenna is not rotating. ON TIME and TX TIME values shown at the bottom of the screen are the time counts in hours and tenths of hour when the radar has been powered.

timer counts

down three

-1.

1.2 Transmitter ON

When the STANDBY status is displayed on the screen, press the transmit switch labeled STBY/TX on the control panel of the display unit.

The radar is initially set to previously used range and pulsewidth. Other settings such as brilliance levels, VRMs, EBLs and menu option selections are also set to previous settings.

The transmit switch toggles the radar between STANDBY and TRANSMIT status. The antenna stops in STANDBY status and rotates in TRANSMIT status.

Quick Start

Provided that the radar was once in use with the transmitter tube (magnetron) still warm, you can turn the radar into TRANSMIT condition without 3-minutes standby. If the Power Switch has been turned off by mistake or the like and you wish to restart the radar promptly, turn on the Power Switch not later than 10 seconds after power-off.

Notes:

1) If the antenna does not rotate in TRANSMIT status, check whether the antenna switch in

the tuning compartment is in the OFF position.

2) The magnetron ages with time resulting in a reduction of output power. It is highly

recommended that the radar be set to STANDBY status when not used for an extended period of time.

Video Freeze-up Recovery

Video freeze-up or lock- up can occur unexpect edly on any di git al r aster scan r adar s. T hi s is mainly caused by heavy spike noise in the power line and can be noticed by carefully watching the nearly visible sweep line. If you suspect that the picture is not updated every scan of the antenna or no key entry is accepted notwithstanding the apparently nor mal pi ctur es, do Quick S tar t to r estor e nor mal operation.

1. Turn off the Power Switch and within 10 seconds turn it on again.

2. Press the Transmit switch labeled STBY/TX for transmit condition. NOTE: This equipment has self-diagnostic function to check operational software periodically. If

Head-up TB (True Bearing) mode

Radar echoes are s hown in the same way as in the

head-up mode. The difference from norm al head- up presentation lies in t he orientation of the bear ing s c ale. The bearing scale is compass stabilized. That is, it rotates in accordance with the c ompass signal, enabling you to know own ship’s heading at a glance.

This mode is av ailable only when the radar is interfac ed

with a gyrocompass.

If the compass fails, the bearing scale returns to the state

of head-up mode.

Description

North-up mode In the north-up mode, target pips are painted at their

measured distances and in their true (compass) directions from own ship, north bearing maintained up of the screen. The heading line changes its direction according to the ship’s heading.

If the gyrocompass fails, the presentation mode changes

to head-up and the north marker disappears. Also, the HDG readout shows asterisks (***.*) And the message GYRO appears in red at the lower-right corner of the screen.

True motion mode Own ship and other moving objects move in accordance

with their true courses and speed. In ground stabilized TM, all fixed targets, such as landmasses, appear as stationary echoes. In the sea stabilized TM without set and drift inputs, the landmass can move on the screen.

When own ship reaches a point corresponding to 75% of

the radius of the display, it is automatically reset to a point of 75% radius opposite to the extension of the heading marker passing through the display center. Resetting can be made at any moment before the ship reaches the limit by pressing the [CU, TM reset]. Automatic resetting is preceded by a beep sound.

If the compass fails, the mode is changed to the head-up

and the north marker disappears. The HDG readout shows asterisks (***.*) and the message GYRO appears in red at the lower-right corner of the screen.

1.10 Selecting the Range Scale

The display range scale is changed by pressing the [+] and [-] keys. The selected range scale and range ring interval are shown at the upper left corner on the screen. When a target of interest comes closer, reduce the range scale so that it appears in 50 - 90 % of the display radius. The range scales are:

0.125−0.25−0.5−0.75−1.5−3−6−12−24−48−96 nm (IMO-type) (Maximum range for Regular type or Japanese version is 72 nm for FR-2115/2115-B or 120

nm for other models)

1.11 Selecting the Pulsel ength

The pulselength in use is displayed at the upper-left position of the screen using the abbreviations shown in the table below.

Appropriate pulselengths are preset to individual range scales and function keys. Therefore, you are not usually required to select them. If you are not satisfied with the current pulselength settings, however, it is possible to change them by the Radar menu operation shown below.

You can choose the pulselength 1 or 2 on the scales 0.5 to 24 nm ranges on FR-2115/2125 models (0.75 to 24 nm ranges on the other models).

Selecting pulsel engt h 1 or 2

1. Press the RADAR MENU key to display the FUNCTIONS 1 menu.

2. Press the [6] key to select PULSELENGTH 1 or 2 as appropriate.

3. Press the RADAR MENU key to close the FUNCTIONS menu.
