IMPORTANT NOTICES
General
How to discard this product
Discard this product according to local regulations for the disposal of industrial waste. For disposal
in the USA, see the homepage of the Electronics Industries Alliance (http://www.eiae.org/) for the
correct method of disposal.
How to discard a used battery
To see if your product has a battery, see the chapter on Maintenance. Follow the instructions be-
low if a battery is used. Tape the + and - terminals of battery before disposal to prevent fire, heat
generation caused by short circuit.
In the European Union
The crossed-out trash can symbol indicates that all types of batteries must
not be discarded in standard trash, or at a trash site. Take the used batter-
ies to a battery collection site according to your national legislation and the
Batteries Directive 2006/66/EU.
In the USA
The Mobius loop symbol (three chasing arrows) indicates that Ni-Cd and
lead-acid rechargeable batteries must be recycled. Take the used batteries
to a battery collection site according to local laws.
In the other countries
There are no international standards for the battery recycle symbol. The number of symbols can
increase when the other countries make their own recycle symbols in the future.

SAFETY INSTRUCTIONS
Indicates a potentially hazardous situation which, if not avoided,
could result in death or serious injury.
Indicates a potentially hazardous situation which, if not avoided,
could result in minor or moderate injury.
The operator must read the safety instructions before attempting to operate the equipment.
Warning, Caution Prohibitive Action Mandatory Action
WARNING
CAUTION
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.
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.
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.
The data from AIS are intended for
reference purposes only.
Check all available navigation aids to
determine target movement.
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.
WARNING WARNING
CAUTION
SAFETY INSTRUCTIONS
iii
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.

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.

1.10.2 Orientation mode
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.
• 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
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
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 0-degree position.
The heading line moves in accordance with
ship's yawing and course change.

True motion (TM)
• NORTH UP
Ground (or water mass) is stabilized with compass and speed inputs. Your ship and
other objects in motion move with their true courses and speed.
• COURSE UP
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.

1.14 How to Reduce the Sea Clutter
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.
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).
2. Put the cursor on the STC setting box at the bottom right corner on the screen.
3. Rotate the setting knob to set the level to use as lowest level for STC adjustment.
4. Open [MAIN MENU], click [ECHO].
5. Click [STC PRESET].
6. Click [ON] to activate the
[STC PRESET] function. The STC
bar is re-scaled to set the STC level
to zero.

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
Within the radar display, the cursor is shown by a plus sign (+). When the cursor is
outside the radar display it comes to an arrow ( ).
Cursor menu
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].
3. Use the touch pad to select the desired menu.
[ACQUIRE]*: Acquires a target (TT or AIS).
[REF MARK]*: Acquire a target to use to gauge own ship’s speed.
[OFFCENTER]: Off-center your position.
[EBL OFFSET]: Shift the origin of an EBL.
*: This function is available for [SEA] mode only.
