Page 3 PREFACE This Field Service Manual describes the structure, I/O specifications and method for maintenance of JMR-7200/JMR-9200 series and JAN-7200/JAN-9200 series. For maintenance, inspection, repair, please use this manual. Keep this manual in a convenient place for future reference. The LCD of this equipment uses thin film transistors (TFT). If some pixels on the screen are not clear, the color is different, or the screen is brighter than usual, it is not because of defect, instead it is because of inherent characteristic of the TFT display technology.
Page 4  Safety Cautions  Cautions for High Voltage High voltages, ranging from several hundreds to tens of thousands of volts, are used in electronic apparatus, such as radio and radar instruments. These voltages are totally harmless in most operations. However, touching a component inside the unit is very dangerous. (Any person other than authorized service engineers should not maintain, inspect, or adjust the unit.) High voltages on the order of tens of thousand volts are most likely to cause instant deaths from electrical shocks.
Page 5  Emergency Measures  Method of First-Aid Treatment Precautions for First-Aid Treatments Whenever a person is struck by an electrical shock, give the patient artificial respiration immediately on the spot, unless it is absolutely necessary to move the patient for safety's sake.
Page 6  Treatment to Give When the Patient Has a Pulse Beating but Has Ceased to Breathe ∗ Performing mouth-to-mouth artificial respiration - Fig. 1 (1) Bend the patient's face backward until it is directed to look back. (A pillow may be placed under the neck.) (2) Pull up the lower jaw to open up the airway.

A person is collapsing. - Secure the safety of the surrounding area. - Secure the safety of the surrounding area. - Prevent secondary disasters. - Prevent secondary disasters. Listen to the appeal of the Responding Check for response.
Page 8 Specific Procedures for Cardiopulmonary Resuscitation (CPR) 1. Check the scene for safety to prevent secondary disasters Are you OK? a) Do not touch the injured or ill person in panic when an accident has occurred. (Doing so may cause electric shock to the first-aiders.) b) Do not panic and be sure to turn off the power.
Page 9 b) If the injured or ill person is breathing, place him/her in the recovery position and wait for the arrival of the emergency services. • Position the injured or ill person on his/her side, maintain a clear and open airway by pushing the head backward while positioning their Roll gently in the opposite mouth downward.
Page 10 2) Perform chest compressions Compress with these • Perform uninterrupted chest compressions of parts (the heels of both 30 at the rate of about 100 times per minute. hands). While locking your elbows positioning yourself vertically above your hands. • With each compression, depress the chest wall to a depth of approximately 4 to 5 cm.
Page 11 side facing the chest. If the pads are not securely attached to the chest, the AED may not function. Paste the pads exactly at the positions indicated on the pads, If the chest is wet with water, wipe dry with a dry towel and the like, and then paste the pads.
Page 12 16. When to stop CPR (Keep the electrode pads on.) a) When the injured or ill person has been handed over to the emergency services b) When the injured or ill person has started moaning or breathing normally, lay him/her on his/her side in a recovery position and wait for the arrival of emergency services.
Page 13  Pictorial Indication  Pictorial Indication Various pictorial indications are included in this manual and are shown on this equipment so that you can operate them safely and correctly and prevent any danger to you and / or to other persons and any damage to your property during operation.
Page 14  Precautions upon Equipment Operation  DANGER Never attempt to check or repair the inside of the equipment. Checking or repair by an unqualified person may cause a fire or an electric shock. Contact our head office, or a nearby branch or local office to request servicing.
Page 15 When turning off the power supply, do not hold down the power button of the operation unit. Otherwise, a trouble may occur due to termination failure. Never directly touch the internal components of the radar antenna or indicator. Direct contact with these high-voltage components may cause electric shock.
Page 16 When cleaning the display screen, do not wipe it too strongly with a dry cloth. Also, do not use gasoline or thinner to clean the screen. Failure will result in damage to the screen surface. Do not change MBS Level/Area unless absolutely necessary. Incorrect adjustment will result in deletion of nearby target images and thus collisions may occur resulting in death or serious injuries.
Page 17 Before starting automatic sailing, be sure to check the safety of the route and the safety when crossing safety contour. Otherwise, accidents may result. If the own ship has arrived at the boundary of a WPT during automatic sailing, be sure to check the safety and perform turning manually by the operator him/herself.
Page 18 Use the radar only as a navigation aid. The final navigation decision must always be made by the operator him/herself. Making the final navigation decision based only on the radar display information may cause accidents such as collisions or running aground. A malfunction as the screen is disordered or unshown may occur if the power in the ship is instantaneously interrupted during operation of the radar.
Page 19 Since these alarms may include some errors depending on the target tracking conditions, the navigation officer himself should make the final decision for ship operations such as collision avoidance. Making the final navigation decision based only on the alarm may cause accidents such as collisions.
Page 20 Do not block the ventilation opening of the equipment. Otherwise, heat may accumulate inside to cause a fire or a malfunction. This equipment is intended for use as an aid to navigation only. • If no backup measures, such as using another ECDIS unit for confirmation, are taken, be sure to use official marine charts together with this equipment to make any navigational decision.
Page 21 During sailing, be sure to check the own ship’s position and bearing as often as necessary, regardless of whether the automatic sailing is in operation or not. Otherwise, accidents may result. Do not turn off the power during Backup/Restore. Otherwise, a function may fail, and an accident may occur. Do not do the backup operation of data while sailing.

In the 3-unit type, the transmitter-receiver unit is installed indoors, away from the scanner unit. In the 2-unit type, the transmitter-receiver unit is installed inside the scanner unit.
Page 75 stopped, the interface circuit switches to the protection mode and forcibly stops transmission and the rotation of the antenna. When the radiator is subjected to external force of wind (corresponding wind speed is greater than 51.5m/s) that exceed the ability to drive the scanner unit, the scanner unit stop to drive the motor.
Page 76 A part of the signal is reflected from a target and received by the antenna. The signal received by the antenna propagates the coaxial cable which is the same as transmitting, and it is input to receiver unit of the TRX module as the reception signal via the circulator. After amplification the signal level by Low Noise Amplifier, the reception RF signal that is input to the receiver unit is downconverted into the reception IF signal by frequency converter unit.

Page 222: Replacement Procedures For Scanner Unit
Replacement Procedures for Scanner Unit Precautions To turn Off the power, do not keep the Power button depressed long. Otherwise, a trouble may occur due to termination failure. Never directly touch the internal components of the Scanner unit or Display unit. Direct contact with these high-voltage components may cause electric shock.
Page 223 Precautions in mounting the cover When the cover is removed for regular inspection and replacement of parts and refitted after such work, the procedures of fastening bolts shall be taken with the following precautions: (1) The proper fastening torque of the fitting bolts (M8) is 1176 to 1470 N•cm (120 to 150 kgf•cm) (which makes the inside water-tight and protects the packings against permanent compressive strain).

Page 226 Coaxial cable (JMR-9230-S3, JMR-7230-S3) The coaxial tube gland of a coaxial cable terminal is fully waterproofed when installed. To prevent a water leakage accident, periodically inspect the coaxial tube gland. In particular, the coaxial tube gland should be repainted every six months. Do not apply strong shock to the coaxial cable by striking it with a tool or hammering it.
