Why is trail data cleared when I turn off my JRC Marine Equipment?
If the power supply is turned off and the trail data is cleared without being stored on your JRC Marine Equipment, it indicates that the processing unit (NDC-1678) is faulty and requires repair from the distributor.
Why is the Gyro compass azimuth not displayed correctly on my JRC Marine Equipment?
If the azimuth of the Gyro compass is not displayed correctly on your JRC Marine Equipment, there are several potential causes: * The communication may not be set correctly, so ensure the communication settings are correct. * The power supply for the Gyro compass equipment might not be on; turn it on. * The connection with the Gyro compass equipment could be abnormal; verify the connection and, if connected to the terminal board circuit (CQD-2322), check if the corresponding LED is lit when the signal is received. If these steps don't resolve the issue, there may be a fault with the internal wiring or the processing unit (NDC-1678), requiring repair from the distributor.
What to do if the radar antenna of my JRC Marine Equipment is not getting power?
If the power is not supplied to the radar antenna of your JRC Marine Equipment, check the following: * Verify the connection with the radar antenna. * Check for any abnormal connections with the radar antenna that may be causing overcurrent protection to activate in the power supply unit; remove any short-circuit causes. * Inspect the 24V DC output fuse; if it's blown, replace it after addressing the cause of the blowout. The fuse is F2. If the issue persists, there may be a fault with the internal wiring, the power supply (NDB-945) inside the processing unit, or the processing unit (NDC-1678) itself, requiring repair from the distributor.
Why is the JRC JMR-5425-9X Marine Radar display frozen, disabling mode selection?
If the display of your JRC Marine Radar is frozen, preventing mode selection, the processing unit (NDC-1678) may be abnormal, requiring repair.
Why are sensor signals not displayed on my JRC Marine Equipment?
If sensor signals are not displayed on your JRC Marine Equipment, there are several potential causes: * The communication may not be set correctly, so ensure the communication settings are correct. * The power supply for the sensor equipment might not be on; turn it on. * The connection with the sensor equipment could be faulty; check the connection and ensure the LED of the corresponding port of the terminal board circuit (CQD-2322) is lit when data is received. * When a sensor is connected to junction box NQE-1143, the power is not supplied to the serial LAN interface (CMH-2370) inside of junction box NQE-1143. Turn on the power supply for the serial-LAN interface circuit. If these steps don't resolve the issue, there may be a fault with the internal wiring, the processing unit...
What causes log data to not display correctly on my JRC JMR-5425-9X 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 the display is frozen on my JRC Marine Equipment?
If the display is frozen on your JRC Marine Equipment, disabling the mode selection screen, it indicates that the processing unit (NDC-1678) is abnormal and requires repair from the distributor.
Why can't radar images be superimposed on my JRC Marine Equipment?
If radar images cannot be superimposed on your JRC Marine Equipment, there are several potential causes: * The connection with the radar antenna is abnormal; check the connection. * The connection with the radar indicator is abnormal; check the connection. If these steps don't resolve the issue, the internal wiring or the processing unit (NDC-1678) may be faulty, requiring repair from the distributor.
Why are characters/symbols not displayed correctly on my JRC JMR-5425-9X?
If characters/symbols are not displayed correctly on your JRC Marine Radar, the processing unit (NDC-1678) may be faulty, requiring repair.
What does it mean when my JRC Marine Equipment displays 'System has detected an error'?
