PREFACE

Thank you very much for purchasing the JRC river radar equipment, JMA-610.

This equipment is a river radar equipment designed to obtain safe operation of ships.

This equipment consists of a radar signal processing unit, a LCD display unit and a scanner unit as its main

units.

٨Before operating the equipment, be sure to read this instruction manual carefully for correct operation.

٨Maintain this instruction manual so that operators can refer to it at anytime.

Refer to this manual when any inconvenience or defect occurs.

negligence may cause death or serious injuries.

WARNING This indication is shown where any person is supposed to be in

danger of being killed or seriously injured if this indication is

neglected and these equipment are not operated correctly.

CAUTION This indication is shown where any person is supposed to be injured

or any property damage is supposed to occur if this indication is

neglected and these equipment are not operated correctly.

Examples of Pictorial Indication

The Umark represents CAUTION (including DANGER and WARNING).

Detailed contents of CAUTION (“Electric Shock” in the example on the

left.) is shown in the mark.

Disassembling

Prohibited

The ;mark represents prohibition.

Detailed contents of the prohibited action (“Disassembling Prohibited” in the

example on the left.) is shown in the mark.

Disconnect the

power plug

The zmark represents instruction.

Detailed contents of the instruction (“Disconnect the power plug “ in the

example on the left.) is shown in the mark.

Warning Label

There is a warning label on the top cover of the equipment.

Do not try to remove, break or modify the label.

- iii -

When conducting maintenance, make sure to turn the

main power off.

Failure to comply may result in electrocution.

Turn off the main power before cleaning the equipment.

Especially when a rectifier is used, make sure to turn it

off since voltage is still outputted from the rectifier

even after the indicator and the radar are turned off.

Failure to comply may result in equipment failure, or

death or serious injury due to electric shock.

When conducting maintenance work on the antenna,

make sure to turn its main power off.

Failure to comply may result in electrocution or

injuries.

Make sure to turn off the antenna operation switch.

Failure to comply may result in injuries caused by

physical contact with the rotating antenna.

PRECAUTIONS٨

DANGER

Never conduct inspection or repair work of equipment

components.

Inspection or repair work by uncertified personnel may

result in fire hazard or electrocution.

For inspection and repair work of equipment

components, consult with our branch office, branch

shop, sales office, or our distributor in your district.

-iv-

Turn off the main power if you need to be near the

scanner unit for maintenance or inspection purposes.

Direct exposure to electromagnetic waves at close

range in death or serious injury.

Turn off the main power source before starting

maintenance.

Otherwise, an electric shock or injury may be caused.

When conducting maintenance work, make sure to turn

off the power and unplug the power line of the

processor so that the power supply to the equipment is

completely cut off.

Some equipment components can carry electrical

current even after the power switch is turned off, and

conducting maintenance work without unplugging the

power connector may result in electrocution,

equipment failure, or accidents.

Turn off the main power before maintenance work.

Otherwise, an electric shock may result.

WARNING

Never carry out internal inspection or repair work of the

equipment by users.

Inspection or repair work by unauthorized personnel

may result in fire hazard or electric shock.

Ask the nearest branch, business office or a dealer for

inspection and repair.

Turn off the main power before cleaning the equipment.

Especially, make sure to turn off the indicator if a

rectifier is used. Otherwise, equipment failure, or

death or serious injury due to electric shock may result,

because voltage is outputted from the rectifier even

when the radar is not operating.

-v-

Set the safety switch for stopping the scanner unit to

the OFF position.

Otherwise, an accidental contact with the rotating

scanner unit may cause injury.

Turn off the main power source before starting

maintenance.

Otherwise, an electric shock or injury may be caused.

Turn off the main power if you need to be near the

scanner unit for maintenance or inspection purposes.

Direct exposure to electromagnetic waves at close

range in death or serious injury.

WARNING

When cleaning the screen, do not wipe it too strongly

with a dry cloth. Also, do not use gasoline or thinner

to clean the screen. Otherwise the screen surface may

be damaged.

Never carry out internal inspection or repair work of the

equipment by users.

Inspection or repair work by unauthorized personnel

may result in fire hazard or electric shock.

Ask the nearest branch, business office or a dealer for

inspection and repair.

Turn off the main power before maintenance work.

Otherwise, an electric shock may result.

Turn off the main power before cleaning the equipment.

Especially, make sure to turn off the indicator if a

rectifier is used. Otherwise, equipment failure, or

death or serious injury due to electric shock may result,

because voltage is outputted from the rectifier even

when the radar is not operating.

-vi-

Set the safety switch for stopping the scanner unit to

the OFF position.

Otherwise, an accidental contact with the rotating

scanner unit may cause injury.

WARNING

CAUTION

Normally, use the automatic tune mode.

Use the manual tune mode only when best tuning is not

possible in the automatic tune mode due to

deterioration of magnetron.

If the gain is too high, unnecessary signals including

receiver noise and false video increase resulting in

reduction of visibility of targets.

On the contrary, if the gain is too low, targets including

ships and dangerous objects may not be clearly

indicated.

When disposing of used lithium batteries, be sure to

insulate the batteries by taping +and

䯹

terminals.

Otherwise, heat generation, explosion or a fire may

occur.

A malfunction may occur if the power in the ship is

instantaneously interrupted during operation of the

radar. In this case, the power should be turned on

again.

-vii -

CAUTION

The accuracy from the vectors are depending on the

accuracy from the (D)GPS sensors.

With longer vectors, the accuracy will be lower.

The vectors are calculated with the situation at that

time. When there will be some changed influence from

wind, water current etc, are not shown before the

vessel is influenced by this.

Do not turn the system off while the display shows

“Copying” in a message area on the bottom center of

the screen in order not to make a flash memory card

damaged.

When using the [RAIN] function, never set the

suppression level too high canceling out all image

noises from the rain or snow at the close range.

Detection of not only echoes from the rain or snow but

also targets such as other ships or dangerous objects

will become inhibited.

When using the [RAIN] function, make sure to choose

the most appropriate image noise suppression level.

When using the [SEA] function, never set the

suppression level too high canceling out all image

noises from the sea surface at close range.

Detection of not only echoes from waves but also

targets such as other ships or dangerous objects will

become inhibited.

When using the [SEA] function, make sure to choose

the most appropriate image noise suppression level.

-viii -

Turn off the main power source before replacing parts.

Otherwise, an electric shock or trouble may be caused.

Before replacing the magnetron, turn off the main

power source and wait for 5 minutes or more until the

high voltage circuits are discharged.

Otherwise, an electric shock may be caused.

Take off your wrist watch when bringing your hands

close to the magnetron.

Otherwise, your watch may be damaged because the

magnetron is a strong magnet.

Two or more persons shall replace the liquid crystal

monitor.

If only one person does this work, he may drop the

LCD, resulting in injury.

Even after the main power source is turned off, some

high voltages remain for a while.

Do not contact the inverter circuit in the LCD with bare

hands. Otherwise, an electric shock may be caused.

CAUTION

Do not put watches, clocks, or magnetic cards close to

the modulator unit since this unit holds magnetrons

having strong magnetic force. Failure or data

destruction of the above devices may result.
