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 log not displayed correctly on my JRC Marine Equipment?
If log values are 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 log equipment might not be on; turn it on. * The connection with the log equipment could be abnormal; verify the connection and, if connected to the terminal board circuit (CQD-2322), check if the corresponding LED blinks 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.
Why is GPS information not displayed on my JRC Marine Equipment?
If position information (GPS) is 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 GPS equipment's power supply might not be on; turn it on. * The GPS equipment may not be performing positioning; check its status. * The connection with the GPS equipment could be abnormal; verify the connection and, if connected to the serial LAN interface circuit, check if the LED of the corresponding port is lit when data is received. If these steps don't resolve the issue, there may be a fault with the internal wiring, the processing unit (NDC-1678), the power supply to the serial LAN interface circuit (CMH-2370) inside junction box NQE-1143, or the serial LAN inte...
Why does the radar antenna on my JRC JMR-5400 not rotate when pressing [TX/ST-BY]?
If the radar antenna of your JRC Marine Equipment does not rotate even if the [TX/ST-BY] button is pressed, consider the following potential causes: * The 24VDC output fuse may be blown. After removing the cause of the fuse blowout, replace the fuse. The fuse is F3. * The motor driver circuit inside of the radar antenna is not set correctly. (When NKE-1632, NKE-2632, or NKE-2632-H is connected as the radar antenna.) Set the motor driver circuit correctly. * The radar antenna rotation unit is frozen. De-freeze the frozen section by using the neck heater option. * Strong wind of relative wind velocity exceeding 100kt (about 51.5m/s) is blowing. When strong wind of relative wind velocity exceeding 100kt is blowing, the radar antenna does not rotate due to the protection function. If...
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.
What to do if the monitor of my JRC JMR-5400 has no power?
If the power is not supplied to the monitor of your JRC Marine Equipment, it may be because the display unit is not activated. Activate the display unit. If the issue persists, the internal wiring or the display (NWZ-208/NWZ-214) may be faulty, requiring repair from the distributor.
What does it mean when my JRC JMR-5400 Marine Equipment displays 'System has detected an error'?
If the following popup window is displayed on your JRC Marine Equipment: "System has detected an error. Turn the power off and on again," it indicates that a communication error has occurred. Close the popup window, and after confirming it is safe to do so, turn the power off and then on again.
