What causes the preheat count down of the radar antenna to not display on JRC JMR-5410-4X?
If the preheat count down of the radar antenna is not displayed on your JRC Marine Radar, it could be due to several reasons: * The connection with the radar antenna is abnormal. Check the connection. * The safety switch of the radar antenna is set to OFF. Set the safety switch to ON. * A solid-state radar antenna is connected. Note that preheat count-down is not displayed for solid-state radar antennas. If the problem continues, the radar antenna, internal wiring, or the processing unit (NDC-1678) may be faulty, requiring repair.
How do I troubleshoot contact signals not outputting on my JRC JMR-5410-4X?
If contact signals are not being output by your JRC Marine Radar, it could be due to: * The power supply for the serial-LAN interface circuit (CMH-2370) is not turned on (in cases where contact signal output is acquired from the serial-LAN interface circuit). Turn on the power supply for the serial-LAN interface circuit. If the issue persists, the internal wiring or the processing unit (NDC-1678) may be faulty, requiring repair.
Why is my JRC JMR-5410-4X Marine Radar not turning on?
Your JRC Marine Radar might not be turning on due to several reasons: * The DC power supply might not be connected. Ensure it is properly connected. * If using a rectifier NBA-5111, the AC power supply might not be connected to it. Connect the AC power supply. * The main power supply at the front of the processing unit (NDC-1678) might not be set to ON. Set it to ON by lifting the lever of the breaker. * The DC power supply might not be within the specified voltage range. Connect it within the correct range. If none of these steps resolve the issue, the internal wiring, the power supply circuit of the processing unit (NDC-1678), or the operation unit (NCE-5794)/optional operation unit (NCE-5605) might be faulty, requiring repair by a distributor.
What to do if sensor signals are not displayed on JRC Marine Radar?
If sensor signals are not displayed on your JRC Marine Radar, consider these potential causes: * The communication may not be set correctly. Ensure the communication is set correctly. * The power supply for the sensor equipment is not turned on. Turn on the power supply. * The connection with the sensor equipment is faulty. Check the connection. Check if the LED of the corresponding port of the terminal board circuit (CQD-2322) is lit at data reception. If a sensor is connected to junction box NQE-1143, ensure the power is supplied to the serial LAN interface (CMH-2370) inside the junction box. If the issue persists, the internal wiring, the processing unit (NDC-1678), or the serial LAN interface circuit (CMH-2370) inside junction box NQE-1143 may be faulty, requiring repair.
How do I fix water depth values not displaying on my JRC Marine Radar?
If water depth values are not displayed on your JRC Marine Radar, consider the following: * The communication may not be set correctly. Set the communication correctly. * The power supply for the echo sounder is not turned on. Turn on the power supply. * The connection with the echo sounder is abnormal. Check the connection. When an echo sounder is connected to the terminal board circuit (CQD-2322), check if the LED of the corresponding port is lit at data reception. If the issue persists, the internal wiring or the processing unit (NDC-1678) may be faulty, requiring repair.
Why is wind direction/wind speed data not displayed on my JRC Marine Radar?
If wind direction/wind speed (anemoscope/anemometer) data is not displayed on your JRC Marine Radar, it could be due to: * Incorrect communication settings. Ensure the communication is set correctly. * The power supply for the anemoscope/anemometer is not turned on. Turn on the power supply. * An abnormal connection with the anemoscope/anemometer. Check the connection. When an anemoscope/anemometer is connected to the terminal board circuit (CQD-2322), check if the LED of the corresponding port is lit at data reception. If the issue persists, the internal wiring or the processing unit (NDC-1678) may be faulty, requiring repair.
Why are rudder angles not displayed correctly on my JRC JMR-5410-4X?
If rudder angles are not displayed, or the values are incorrect on your JRC Marine Radar, consider the following: * The communication may not be set correctly. Ensure the communication settings are correct. * The power supply for the rudder angle indicator may not be turned on. Turn on the power supply. * The connection with the rudder angle indicator may be abnormal. Check the connection. When a rudder angle indicator is connected to the terminal board circuit (CQD-2322), check if the LED of the corresponding port is lit at data reception. If the issue persists, the internal wiring or the processing unit (NDC-1678) may be faulty, requiring repair.
What causes log data to not display correctly on my JRC JMR-5410-4X Marine Radar?
If log data is not displayed or the values are incorrect on your JRC Marine Radar, it may be due to: * Incorrect communication settings. Ensure the communication is set correctly. * The power supply for the log equipment is not turned on. Turn on the power supply. * An abnormal connection with the log equipment. Check the connection. When log equipment is connected to the terminal board circuit (CQD-2322), check if the corresponding LED blinks at signal reception. If the issue persists, the internal wiring or the processing unit (NDC-1678) may be faulty, requiring repair.
What to do if my JRC Marine Radar trackball is not moving smoothly?
If the trackball on your JRC Marine Radar does not move smoothly, the trackball might be dirty. Clean the trackball.
