IMPORTANT
READ ALL INSTRUCTIONS carefully and com-
pletely before attempting to operate the marine radar.
SAVE THIS INSTRUCTION MANUAL. This
manual contains important safety and operating in-
structions for the MR-570R.
RNEVER let metal, wire or other objects touch any
internal part of the radar.
RNEVER place the radar within the reach of chil-
dren.
RNEVER expose the display unit to rain, salt water
or any other liquids.
NEVER connect the radar to AC or more than 42 V
DC. This will damage the radar.
AVOID placing the display unit in excessively dusty en-
vironments or in direct sunlight.
AVOID placing the display unit near heating equipment
or in direct sunlight or where hot or cold air blows di-
rectly onto it.
AVOID using the scanner unit in areas where the tem-
perature is below –25˚C (–13˚F) or above +70˚C
(+158˚F). AVOID using the display unit in areas where
the temperature is below –15˚C (+5˚F) or above +55˚C
(+131˚F).
AVOID using strong solvents such as benzene or al-
cohol for cleaning the radar, as they may damage the
surfaces.

CAUTION
1
The MR-570R is supplemental aids to navigation and are not intended to be a substitute for
accurate and current nautical charts.
DANGER! HIGH VOLTAGE
• NEVER OPEN THE UNIT
This product contains high voltage that could be FATAL. This product has no user-servicable
parts inside.All repairs and adjustments MUST be made by a qualified electronics technician
at your Marine Navigation Dealer.
• HIGH VOLTAGE
High voltages of up to 3,500 volts are used in this equipment.Although prudent measures for
safety have been adopted, sufficient care must be taken in the operation, maintenance and
adjustment of the equipment.
Electric shock of 1,000 volts or more may cause electrocution and death; even an electric
shock of only 100 volts may be fatal.
• PREVENTION OF ELECTRIC SHOCK
(FOR QUALIFIED ELECTRONIC TECHNICIANS ONLY)
To prevent such accidents, turn OFF the power source and do not reach inside the unit until
you have:
q Discharged the capacitors by disconnecting the power cable from the power source for 5
min.;
w 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.
RADIATION HAZARD
• Radiation emitted from the scanner unit can be harmful, particularly to the eyes. To avoid harm-
ful radiation, ensure the radar power is in the OFF position before beginning work on the scan-
ner unit.
•The maximum distances from the antenna at which radio frequency radiation levels of 100
W/m2and 10 W/m2as follows.

Before turning the power ON, be sure all the connec-
tions are complete. The checklist at right may be help-
ful for necessary confirmation.
•Checklist
qThe 4 bolts securing the scanner unit must be firmly
tightened.
wCabling must be securely attached to a mast or
mounting material, and must not interfere with the
rigging.
eBe sure waterproofing procedures are completed
on the system cable.
rThe power connections to the battery must be of the
correct polarity.
tBe sure that the plugs at the rear of the display unit
have been connected correctly and securely.

BASIC OPERATION
•Heading Line marker
The heading marker is a line that shows your ship’s
bow direction. (This marker will appear in the center of
the screen when the Head-up screen H UP is se-
lected.) The heading marker can be hidden when the
desired target is located under the heading marker.
•Push and hold [ADJ] and [MENU] simultaneously to hide
the heading marker.
qTurn the power ON.
wPush [TX] after the countdown disappears from the
screen.
•See “Turning power ON/OFF”on page at left.
ePush [+] or [–] key one or more times to select the
display range.
•The screen range readout shows the maximum range of
the screen.
rPush [ADJ] then adjust the [GAIN]* to be on the
threshold of max. screen range.
•Increases the gain.
•Increased gain may increase screen noise.
tSelect [SEA]*, then set the [SEA]* to minimum.
yPush [MODE] to select one of HUP (Head-up), CUP
(Course-up), NUP (North-up) or True motion TM
screens.
C UP, NUP or TM can be selected only when bear-
ing, position or speed data are connected.
(See p. 26 for details)
*Select each item ,then push [ADJ] for 0.5 sec. to

• Brilliance adjustment
The intensity of the screen can be adjusted. When you
require continuous operation, but not constant viewing,
a lower setting can increase the life of the backlight.
• Key illumination
The backlighting of the keys can be adjusted for con-
venient operation. (p. 6)
•Key illumination corresponds with [BRILL] control.
NOTE: High intensity will shorten the life of the back
light.
•Fixed range rings
The fixed range rings can be used for rough distance
measurement. (p. 14)

push []to select RING. Push []to turn the ring ON.
CAUTION: When setting the [SEA] control to MAX posi-
tion, close targets are blanked.

4BASIC OPERATION
The followings are typical basic operation examples,
which may hinder radar reception (sea clutter, precip-
itation interference and echoes from other radar).
■SEA function
This function serves to eliminate echoes from waves
at close range. Reduce the receiver gain for close ob-
jects within a radius of 8 miles to eliminate sea clutter.
•Push and hold [ADJ] for 0.5 sec. to activate the automatic
control function.
■RAIN function
This function eliminates reflection echoes from rain,
snow, fog etc.
•Adjust the lowest level to deactivate the control function.
•NOTE: DO NOT reduce the reflection echoes too much,
otherwise you may miss weaker targets.
WARNING: The [SEA] control reduces the re-
ceiver sensitivity of objects within 8 miles. Therefore,
caution and careful adjustment are necessary when
using the [SEA] control.
Small objects may not be displayed on the screen
when strong echoes from the rain or the island within
1 NM while automatic SEA function is activating.

■OFF CENTER function
The scanning area can be shifted in a desired direc-
tion and can be enlarged partially. This is useful when
the Head-up* is selected and you want to enlarge the
bow direction display, or, the center of the screen
shifts in the direction of the intersection.
•This function is available within, and up to a 24 NM range.
*This function is not available in the TM screen.
qPush []/[]/[]/[ ]key to move the cursor
where you want to shift the center of the screen.
•Max. offsetting is up to 56% of the screen.

■Power save function
The power save function conserves the boat’s battery
power by pausing the transmission. The standby
(pausing) times are selectable (*rotation number is
fixed on 10 rotations).
For example, when 1 min. is selected, the scanner ro-
tates 10 revolutions; then stops for 1 min., and then re-
peats this sequence while the power save function is
activated.
•Setting the scanning standby time
qPush [MENU] to call up the “FUNCTION”menu.

comes highlighted.
ePush []/[ ]to select standby time.
•1, 6, 15, and 30 min. are available.
rPush [MENU] twice to exit the menu display.
•Using the “POWER SAVE” function
qPush and hold [TX (SAVE)] for 0.5 sec. to turn the
power save function ON.
•The save indicator appears in the top of the screen.
wAfter the scanning rotations are finished, transmis-
sion and rotation are suspended until the selected
standby time elapses.
•The display shows the last scanned echoes until the
scanning restarts.
•“SAVE”appears in the top of the screen.
eAfter the selected standby time elapses, transmis-
sion and rotation restart.
rPush [TX (SAVE)] to cancel the power save func-
tion.
•The save indicator turns OFF.
NOTE: When you use the power save function to-
gether with the alarm function, the LCD display is
turned OFF until an object enters the programmed
alarm zone, therefore, more power saving is possi-
ble. (p. 00)
