PRECAUTIONS

For Display unit:

R

WARNING! NEVER let metal, wire or other

objects touch any internal part of the display unit. This
may result in an electric shock.

R

WARNING! NEVER apply AC voltage to the

DC connector of the display unit. This may pose a fire
hazard, result in an electric shock or damage the dis­play unit.

R

WARNING! NEVER apply more than 42 V DC

to the DC connector of the display unit. This may pose
a fire hazard or damage the display unit.

R

WARNING! NEVER touch the display unit with

wet hands. This may result in an electric shock or dam­age the display unit.

R

WARNING! NEVER open the display unit.

There are no user adjustment points. This may result in
an electric shock and incorrect reassembly may cause
a fire hazard.

CAUTION: NEVER connect the display unit to a

DC power source using reverse polarity. This will dam­age the display unit.

CAUTION: NEVER remove the fuse holder from

the DC power cable. This will damage the display unit.

DO NOT place the display unit in excessively dusty

environments.

DO NOT place the display unit near heating equip-

ment or in direct sunlight or where hot or cold air blows
directly onto it.

DO NOT use or place the display unit in areas with

temperature below –15˚C (+5˚F) or above +55˚C
(+131˚F).

DO NOT use harsh solvents such as benzine or alco-

hol when cleaning the display unit, as they will damage
the display unit’s surfaces.

DO NOT place the display unit in areas that will block

air passage or put anything around the display unit.
This will obstruct heat dissipation.

KEEP the display unit out of the reach of children.
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 appear as small dark or light spots. This is not a
malfunction or defect, but a normal characteristic of
LCD display.

For Scanner unit:

R

DANGER: 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 qualified electronics technician at your
Marine Navigation Dealer.

For qualified electronics technician only:

R

DANGER: HIGH VOLTAGE! High volt-

ages of up to 3,500 volts are used in the scanner
unit. Although prudent measures for safety have
been adopted, sufficient 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! To prevent

an electric shock, turn the
do not reach inside the scanner unit until 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 safest 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 the eyes. To avoid harm­ful radiation, turn
beginning work 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 units meet IPX6* requirements for high­pressure water jet resistance.
However, if these items are 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.

DSLOW WARN

The AIS unit calculated COG (Course Over Ground)
data of a vessel that is at anchor or drifting is unre­liable, and therefore the CPA (Closest Point of Ap­proach) 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: Turn OFF the Slow Warn function.

• 0.1 to 4.9KT: Select the vessel’s speed.

DLOST AIS TRGT
