SECTION 7 TROUBLE SHOOTING 7.1 Fault Finding.................................................. 7-3 7.2 Trouble Shooting........................................... 7-4 7.3 Replacement of Major Parts ......................... 7-6 7-1 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 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. For operating the radar equipment in the good conditions, it is necessary to make the maintenance work as described below. If maintenance is made properly, troubles will reduce. It is recommended to make regular maintenance work. Common points of maintenance for each unit are as follow: Clean the equipment. Remove the dust, dirt, and sea water rest on the equipment cabinet with a piece of dry cloth. Especially, clean the air vents with a brush for good ventilation. 7-2 7. TROUBLE SHOOTING yyy yyyy 7 WARNING 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. 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. 7-3 7.1 FAULT FINDING In case of semiconductor circuits, it is deemed that there are few cases in which the used semiconductor devices have inferior quality or performance deterioration except due to insufficient design or inspection or by other external and artificial causes. In general, the relatively many causes are disconnection in a high-value resistor due to moisture, a defective variable resistor and poor contact of a switch or relay. Some troubles are caused by defective parts, imperfect adjustment (such as tuning adjustment) or insufficient service (such as poor cable contact). It will also be effective to check and readjust these points. Melted fuses are caused by any clear cause. When a fuse is replaced, it is necessary to check the related circuits even if there is no trouble. In checking, note that there is some dispersion in the fusing characteristics.

RIVER RADAR EQUIPMENT INSTRUCTION MANUAL - i - PREFACE Thank you very much for purchasing the JRC marine 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. ● Before operating the equipment, be sure to read this instruction manual carefully for correct operation. ● Maintain this instruction manual so that operators can refer to it at anytime. Refer to this manual when any inconvenience or defect occurs. - ii - ●BEFORE OPERATION● Pictorial Indication Various pictorial indications are included in this manual and are shown on these equipment so that you can operate them safety and correctly and prevent any danger to you and/or to other persons and any damage to your property during operation. Such indications and their meanings are as follows. Please understand them before you read this manual: DANGER This indication is shown where incorrect equipment operation due to 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 Electric Shock The U mark 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 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 - 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. 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. ●PRECAUTIONS● DANGER - iv - WARNING Never carry out internal inspection or repair work of the equipment by users.
