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.
