It has powerful transmitting power, a 12.1-inch LCD

display and many other advanced features.

If you have any questions regarding the operation of

the radar, contact your nearest authorized Icom Inc.

dealer.

IMPORTANT

READ THIS INSTRUCTION MANUAL

CAREFULLY before attempting to operate the

radar.

SAVE THIS INSTRUCTION MANUAL. This

manual contains important safety and operating

instructions for the MR-1200RII/TII/TIII.

WORD DEFINITION

RDANGER! Personal death, serious injury or an

explosion may occur.

RWARNING! Personal injury, ﬁre hazard or electric

shock may occur.

CAUTION Equipment damage may occur.

NOTE

If disregarded, inconvenience only.

No risk of personal injury, fire or

electric shock.

BE CAREFUL!

SART signals may not be detected and may

not be displayed on the screen depending

on the SEA, RAIN or IR settings.

Follow the settings as below to detect the

SART signals on the screen.

qSelect the screen range between 6 NM

to 12 NM with [+/–]. (p. 1)

wSet the [GAIN] as high as possible. (p. 2)

eSet the [SEA] to minimum. (p. 2)

rSet the [RAIN] to minimum. (p. 2)

tTurn OFF the [IR] function. (p. 11)

yTurn OFF the [STRETCH] function.

The MR-1200RII/TII/TIII are supplemental aids to navigation and are not intended to be a

substitute for accurate and current nautical charts.

iii

For Display unit:

WARNING! NEVER let metal, wire or other

objects touch any internal part of the display unit. This

may result in an electric shock.

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 dis-

play unit.

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.

WARNING! NEVER touch the display unit with

wet hands.This may result in an electric shock or dam-

age the display unit.

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 dam-

age 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, scan-

ner 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:

DANGER: HIGH VOLTAGE! NEVER open

the scanner unit. The scanner unit contains high volt-

age that could be fatal. And there are no user adjust-

ment points. All repairs and adjustments MUST be

made by a qualiﬁed electronics technician at your

Marine Navigation Dealer.

For qualiﬁed electronics technician only:

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.

RDANGER: HIGH VOLTAGE! To prevent

an electric shock, turn the

radar

’s power is OFF and

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 de-

vice.

Also, it is safest to wear dry insulated rubber gloves.

NEVER use both hands simultaneously; keep one

hand in your pocket.

WARNING: RADIATION HAZARD!

Radiation emitted from the scanner unit can be

harmful, particularly to the eyes. To avoid harm-

ful radiation, turn

the radar’s power is OFF

before

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 high-

pressure 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 require-

ments while connecting to the radar unit.
