WARNING

Do not open the equipment.

The equipment uses high voltage that
can cause electrical shock. Refer any
repair work to a qualified technician.

Before turning on the radar, be sure
no one is near the antenna.

Prevent the potential risk of being
struck by the rotating antenna, which
can result in serious injury or death.

If water leaks into the equipment or
something is dropped into the
equipment, immediately turn off the
power at the switchboard.

Fire or electrical shock can result.

If the equipment is giving off smoke
or fire, immediately turn off the
power at the switchboard.

Fire or electrical shock can result.

If you feel the equipment is acting
abnormally or giving off strange
noises, immediately turn off the
power at the switchboard and
contact a service technician.

WARNING

WARNING

Do not disassemble or modify the
equipment.

Fire, electrical shock or serious injury
can result.

Make sure no rain or water splash
leaks into the equipment.

Fire or electrical shock can result if
water leaks into the equipment.

Do not place liquid-filled containers
on or near the equipment.

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

SAFETY INSTRUCTIONS

The TT tracks and plots the movement of
up to 100 radar targets and fully complies
with IMO standards for TT.
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.)

- Echo intensity

- Radar transmission pulse width

- Radar bearing error

- Gyrocompass error

- Course change (own ship and target)

▪ The amount of tracking delay is inversely

proportional to the relative speed of the
target. Delay is approx. 15-30 seconds for
the higher relative speed; approx. 30-60
seconds for the lower relative speed. The
following factors can affect accuracy:

The data generated by TT and AIS are
intended for reference only.

Refer to official nautical charts for detailed
and up-to-date information.

CAUTION

The data from AIS are intended for
reference purposes only.

Check all available navigation aids to
determine target movement.

CAUTION

Do not operate the equipment with
wet hands.

Electrical shock can result.

Keep objects away from the antenna
unit, so as not to impede rotation of
the antenna.

Fire, electrical shock or serious injury
can result.

Use the proper fuse.

Use of the wrong fuse can cause fire or
electrical shock.

Do not depend on one navigation
device for the navigation of the ship.
The navigator must check all aids
available to confirm position.

- The TT (Target Tracking) automatically
tracks an automatically or manually
acquired radar target and calculates its
course and speed, indicating them with
a vector. Since the data generated by
the TT depends on the selected radar
targets, the radar must be optimally
tuned for use with the TT, to ensure
required targets will not be lost or
unnecessary targets like sea returns
and noise will not be acquired and
tracked.

- A target is not always a landmass,
reef, ship, but can also be returns from
the sea surface and from clutter. As
the level of clutter changes with the
environment, the operator must
correctly adjust the sea and rain clutter
controls and the gain control so that
the target echoes do not disappear
from the radar screen.

FOREWORD

A Word to the Owner of the FR-1908V-BB/FR-1918V-BB Radar

Congratulations on your choice of the FR-1908V-BB/FR-1918V-BB Radar.

Please carefully read the safety information and operating instructions set forth in this manual be­fore attempting to operate the equipment and conduct any maintenance. Your radar set will per­form to the utmost of its ability only if it is operated and maintained in accordance with the correct
procedures.

Features

The FR-1908V-BB/FR-1918V-BB consists of an antenna unit, processor unit, and control unit and
is designed to meet the requirements of navigation radar used on inland waterways. Radar targets
are displayed on a vertically oriented SXGA display, in a single color or gradations of green or
cyan according to echo strength. A 17 to 19 inch display with SXGA (or equivalent) resolution is
recommended. Larger displays may result in dim images. Further, if the aspect ratio of the display
is different from SXGA, images may be distorted. Also, displays larger than 19 inches and having
the same aspect ratio as SXGA may have a “blank” display area at the top and bottom of the
screen.

Following are the main features.

• Displays inland AIS targets

• Easy switching between River and Sea modes

• Automatic capture of the radar display

• Alarm history with Alarm log

• Graph displays: ROT, Rudder and AutoPilot

• TT (Track target) function to watch other ships’ movement

• Large capacity memory - Mark/Line: max. 5,000 points, TT: 100 targets, AIS: 300 targets

Program No.

1.3 How to Transmit

To transmit, press the STBY/TX key while [STBY] is displayed. Radar echoes are dis­played on the screen with the previously used settings of range.

Each press of the STBY/TX key switches between stand-by and transmit (You can
also switch between stand-by and transmission by clicking the [STBY/TX] indication.).
The antenna is stopped in stand-by, and rotates in transmission.

The magnetron in the antenna unit generates the radar pulses and decays over time.
To extend the life of the magnetron, keep the radar in stand-by when its use is not re­quired.

1.4 Radar Display Indications

The illustration below shows all the icons and symbols (both in the [RIVER] and [SEA]
modes) that may appear on the display. Some icons or symbols may not be shown
depending on the display mode.

1.10 Operation Modes

This radar has two operating modes: river mode and sea mode.

• The river mode provides a specialized radar display for river navigation.

• The sea mode provides the traditional radar display.

1.10.1 How to select an operation mode

Click the operation mode icon at the top left corner of the screen to select [RIVER] or
[SEA].

Note 1: To enable switching of the operation mode, the [OPERATION TYPE] setting,
in the [SERVICE MENU], must be set to [RIVER-SEA]. See your dealer.

Note 2: To change the operation mode ([RIVER] or [SEA]), go to [STBY] once to se­lect the operation mode then go to [TX] mode.

The following items are set according to the operation mode.

• Orientation mode

• Range

• Units

• Screen size (River mode: circle* only, Sea mode: circle* and wide*)

1.10.2 Orientation mode

North marker

Heading
line

North mark

Heading
line

Relative motion (RM)

In relative motion, own ship position is stationary on the screen to observe relative mo­tion of surrounding targets.

• HEAD UP
The head-up mode is a display in which the line
connecting own ship and the top of the display
indicates own ship's heading. The target pips
are painted at their measured distances and in
their directions relative to own ship's head­ing.The short line on the bearing scale is the
north marker, which indicates heading sensor
north.

• HEAD UP (TB)
Radar echoes are shown in the same way as in the head-up mode. The difference
from normal head-up presentation lies in the orientation of the bearing scale. The
bearing scale rotates in accordance with the heading sensor signal, enabling you to
know own ship's heading at a glance.
This mode is available when the radar is interfaced with a gyro heading sensor. If
the gyro heading sensor fails, the bearing scale returns to the state of head-up
mode.

1. OPERATION

• STERN UP
A display without azimuth stabilization in which the line that connects the center with
the top of the display indicates your stern.

• NORTH UP
The north-up mode paints target pips at their
measured distances and in their true (heading

North mark

sensor) directions from own ship, north bearing
is fixed at the top of the screen. The heading
line changes its direction according to the
ship's heading. This mode requires heading

Heading
line

signal.
If the compass fails, the orientation mode
changes to head-up and the north marker dis­appears.

• COURSE UP
The course-up mode is an azimuth stabilized
display in which a line connecting the center
with the top of the display indicates own ship's
intended course (namely, own ship's previous
heading just before this mode has been select­ed).Target pips are painted at their measured
distances and in their directions relative to the
intended course, which is maintained at the 0­degree position. The heading line moves in ac­cordance with ship's yawing and course
change.

STC PRESET [ON]

The reflected echoes from the waves
appear around your ship and are
called “sea clutter”. The sea clutter
extends according to the height of
waves and antenna above the water.
When the sea clutter hides the tar­gets, reduce the clutter, either manu­ally or automatically.

1. Click the STC mode icon at the bottom right corner on the screen to show [MAN]
or [AUTO] as appropriate.

1. OPERATION

2. For manual adjustment, rotate the setting knob to adjust the sea clutter so that the
clutter is broken into small dots, and small targets become identified. If the setting
is too low, targets are hidden in the clutter. If the setting is too high, both sea clutter
and targets disappear from the display. Normally adjust the control until the clutter
has disappeared to leeward, but a small amount of the clutter is visible windward.
For auto mode, the setting range is -50 to 50. For manual mode, 0 to 100.

STC PRESET

You can tune STC properly with the [STC PRESET] function.

1. Click the STC mode icon to set [MAN] (Manual mode).

1.15 How to Reduce the Rain Clutter

The reflections from the rain or snow appear on the screen. These reflected echoes
are called “rain clutter”. When the rain clutter is strong, targets in the rain clutter are
hidden in the clutter. Reflections from the rain clutter are easily identified from true tar­gets by their wool-like appearance.

The rain control breaks the continuous display of rain or snow reflections into a ran­dom pattern. When the rain clutter hides the targets, adjust the rain control (automatic
or manual) to reduce the clutter.

1. Click the rain mode icon at the bottom right corner on the screen to show [MAN]
or [AUTO] as appropriate.

2. For manual adjustment, rotate the setting knob to reduce the rain clutter.
For auto mode, the setting range is -50 to 50. For manual mode, 0 to 100.

1.16 Cursor

Functions that require the use of the cursor, such as EBL offset, may be activated di­rectly from [CURSOR MENU]. This menu is available when the cursor is inside the ef­fective display area.

1. Put the cursor anywhere within the radar display.

2. Press the right button to show [CURSOR MENU].
