maintenance and inspection.
0093169010-10 iii
For Your Safe Operation MDC-7000/7900 Series
Caution, high voltage inside.
High voltage that may cause severe injury or death is present. High
voltage remains in circuit even after power is turned off. High voltage
circuit has a protective cover with a warning label. Make sure to turn off
power and discharge capacitors before working on the system. Only
authorized personnel should access this circuit for repair and
maintenance.
Confirm main power is turned off before servicing the
equipment.
If power switch is turned on while working on the system, possible
severe injury or death may occur due to high voltage. Make sure main
power is off and a label “Work In Progress” is attached to the breaker
powering the system.
Caution related to dust
Inhaling dust may cause A respiratory disease. When cleaning the inside
of equipment, be careful not to inhale dust. Wearing a safety mask is
recommended.
When choosing equipment location
Do not install the equipment where it is excessively damp, humid and
under direct dripping water.
Caution related to static electricity
Static electricity may be generated from floor carpet or synthetic clothes.
Static may destroy some electronics parts of the circuit and therefore
anti-static measures should be done.
Prohibited matter
Any Display and Scanner unit combination other than specified in the
manual is prohibited and will void manufacturer’s warranty.
Caution related to Equipment
iv 0093169010-10
MDC-7000/7900 Series For Your Safe Operation
Caution related to rotating aerial
The radar antenna may start rotating to rotate without notice. Please stand
clear from the antenna for your safety.
Caution related to electromagnetic disturbance
The operating Antenna & Scanner unit radiates high-energy
electromagnetic wave. It may cause harmful effect for human body due to
its continuous radiation. As International regulation says, electromagnetic
waves less than 100 watt/m2 does not have a harmful effect on human
bodies, but some kind of medical devices such as heart pacemakers are
sensitive even under the low energy electromagnetic wave. Any personnel
with such a device should keep away from the electromagnetic wave
generating position at all times.

For Your Safe Operation MDC-7000/7900 Series
Do not disassemble or modify. It may lead to trouble, fire, smoking or
electric shock. In case of trouble, contact our dealer or our company.
In case of smoke or fire, switch off the power in the boat and the power of
equipment. It may cause fire, electric shock or damage.
Caution related to remaining high voltage.
A high voltage may remain in the capacitor for several minutes after
system is powered off. Before inspecting inside, wait at least 5 minutes
after powering off or discharging the remaining electricity in an appropriate
manner. Then, start the work.
The information displayed in this unit is not provided directly for your
navigation. For your navigation, be sure to see the specified material.
Use properly rated fuse. If incorrect fuse is used, it may cause fire, smoke
or damage.

MDC-7000/7900 Series Break in procedure of stored radar
Following procedure is recommended for “Break In” of the stored radar.
Otherwise the radar sometimes exhibits unstable transmitting operation
such as arcing at its initial operation after long period of storage and make
the operation more difficult.
1. Extend preheat time as long as possible (preferably 20 to 30
minutes).
2. Set the pulse width to the shortest one and start the operation.
When the operation in the shortest pulse is stable then go to
operation in longer pulse and repeat the similar step until the
operation reaches to the final pulse condition.
Break in procedure of stored radar
0093169010-10 vii
Used battery and radar disposal MDC-7000/7900 Series
A high-energy density lithium ion battery is installed in this radar.
Improper disposal of a lithium ion battery is discouraged as the battery
has a possibility of short-circuiting. If it gets wet, the generation of heat,
explosion or ignition may occur resulting in an injury or fire.
Used battery and radar disposal
Treatment of the used lithium ion battery
To dispose of built-in lithium ion battery (CR2032) in this radar, insulate each terminal with tape, and
wrap in plastic bag.
The disposal and collection rules may be different depending on each municipal district. Obey the
directions of each district.
Disposal of this radar
This radar shall be disposed according to the municipal regulations or rules.

MDC-7000/7900 Series In case no Heading and Speed signals
In case no Heading and Speed signals are input from navigation
equipment
When no Heading and Speed signals are input from navigation equipment (in case not connected), this
radar gives alarms and warning messages at lower right of the display, if the radar is started up factory
default settings.
These alarms are disengaged by pressing OFF key temporarily, however, the alarms are activated
again next time the radar is start up.
Disengage the alarm detection function on start up by the following. Once set, the alarm is not detected
next time the radar is started up.
Press MENU key to display “Menu”.
Select [ALARM] => [ALARM ON/OFF] => [I/O] => [HDG INPUT] => [OFF], and press ENT key.
