PRECAUTIONS
For Display unit:
RWARNING! NEVER let metal, wire or other
objects contact the inside of the display unit, or make
incorrect contact with connectors on the rear panel.
This could cause an electric shock or damage the
display unit.
RWARNING! NEVER apply AC voltage to the DC
connector of the display unit. This could cause a re
or damage the display unit.
RWARNING! NEVER apply more than 42 V DC
to the DC connector of the display unit. This could
cause a re or damage the display unit.
RWARNING! NEVER touch or operate the display
unit with wet hands. This could cause an electric
shock or damage the display unit.
RWARNING! NEVER open the display unit. There
are no user adjustment points. This could cause an
electric shock and incorrect reassembly may cause a
re hazard.
RWARNING! NEVER operate the radar during a
lightning storm. It may result in an electric shock,
cause a re or damage the display unit. Always
disconnect the power source and scanner unit before
a storm.
RWARNING! NEVER reverse the DC power cable
polarity. This could cause a re or damage the display
unit.
RWARNING! NEVER remove the fuse holder on the
DC power cable. Excessive current caused by a short
could cause a re or damage the display unit.
CAUTION: DO NOT use or place the display unit in
areas with temperature below –15˚C (+5˚F) or above
+55˚C (+131˚F).
CAUTION: DO NOT
use harsh solvents such as
Benzine or alcohol when cleaning, the display unit, as
they will damage the display unit surfaces.
CAUTION: DO NOT place the display unit in
excessively dusty environments.
DO NOT place the display unit near heating
equipment or in direct sunlight or where hot or cold
air blows directly onto it.
DO NOT place the display unit in areas that could
block air passage or put anything around the display
unit. This will obstruct heat dissipation.
KEEP the display unit out of the reach of
unauthorized persons.
KEEP the display unit away from heavy rain, and
never immerse it in the water.
The display unit meets IPX4 requirements for splash
resistance when the supplied connection cable,
scanner unit are connected.
However, if it is dropped, splash resistance cannot be
guaranteed because of possible damage to the case
or the waterproof seals.
The LCD display may have cosmetic imperfections
that is displayed as small dark or light spots.This is not
a malfunction or defect, but a normal characteristic of
LCD display.
For Scanner unit:
RDANGER: HIGH VOLTAGE! NEVER open the
scanner unit. The scanner unit contains high voltage
that could be fatal. And there are no user adjustment
points. All repairs and adjustments MUST be made
by a qualied electronics technician at your Marine
Navigation Dealer.
For qualified electronics technician only:
R DANGER: HIGH VOLTAGE! High voltages of up to
3,500 volts are used in the scanner unit. Although
prudent measures for safety have been adopted,
sufcient care must be taken in the operation,
maintenance and adjustment of the scanner unit.
Electric shock of 1,000 volts or more may cause
electrocution and death, even an electric shock of
only 100 volts may be fatal.
R DANGER: HIGH VOLTAGE! DO NOT turn OFF the
radar ’s power and do not reach inside the scanner
unit before you have:
• discharged the capacitors by disconnecting the
system cable from the radar unit for 5 minutes.
• checked that no electric charges remain inside
the device.
Also, it is recommended to wear dry insulated
rubber gloves. NEVER use both hands
simultaneously, keep one hand in your pocket.
R WARNING: RADIATION HAZARD!
Radiation emitted from the scanner unit can be
harmful, particularly to your eyes. To avoid harmful
radiation, turn OFF the radar’s power before
working on the scanner unit.
DO NOT use or place the scanner unit in areas with
temperature below –25˚C (–13˚F) or above +70˚C
(+158˚F).
NEVER immerse the scanner unit in the water.
The scanner unit meets IPX6
* requirements for high-
pressure water jet resistance.
However, if the scanner unit is dropped, high-
pressure water jet resistance cannot be guaranteed
because of possible damage to the cases or the
waterproof seals.
* Except for the cable connectors. They meet IPX4
requirements while connecting to the radar unit.

real movement over ground. Therefore,
a stopped targetʼs trail is not displayed.
The true trail requires a heading signal and
your own vesselʼs position information.
• Relative: The trail of other vessels is relative to your
vessel. In this mode, other vesselsʼmove-
ment and your vesselʼs movement are com-
bined, so Relative trail is valid if you want to
look at the relative movement to avoid col-
lisions. However, a stopped targetʼs trail is
also displayed. In that case, it is difficult to
see in some places such as near Islands.
Regardless of this setting, the display acts as the

DSlow Warn
The AIS unit calculated COG (Course Over Ground)
data of a vessel that is at anchor or drifting is unre-
liable, and therefore the CPA (Closest Point of Ap-
proach) and TCPA (Time to CPA) data may not be
correctly calculated. If a vessel is anchored in your
alarm zone, the unreliable data can cause the collision
alarm to sound many times, even if there is no real
danger. To prevent this, when the anchored vessel’s
SOG (Speed Over Ground) is less than this set value,
the Slow Warn function assumes that vessel’s COG
is fixed towards your vessel and an alarm will sound.
• OFF: Turns OFF the Slow Warn function.
• ON: Turns ON the Slow Warn function.
DSlow Warn Speed
