    How do I fix JRC Monitor when the azimuth of the Gyro compass is not displayed?
    • K
      Kathy GloverNov 25, 2025
      If the azimuth of the Gyro compass isn't displaying correctly on your JRC Monitor, or the rotation direction is wrong: * Verify that the communication is set correctly. * Ensure the power supply for the Gyro compass equipment is turned on. * Check the connection with the Gyro compass equipment, looking for the LED indicator at signal reception if connected to the serial LAN or gyro interface circuit. * If using the serial-LAN interface circuit (CMH-2370), confirm its power supply is on. * If using the Gyro interface circuit (CMJ-554), ensure it is set correctly and check its fuse. If the issue persists, the serial-LAN interface circuit (CMH-2370), the Gyro interface circuit (CMJ-554), internal wiring, or the central control unit (NDC-1590) may be faulty, requiring a repair requ...

    What to do if position information (GPS) is not displayed on JRC Monitor?
    • C
      Christopher MarksAug 25, 2025
      If the GPS information isn't showing on your JRC Monitor, verify these items: 1. Ensure the communication is correctly set. 2. Check that the power supply for the GPS equipment is on. 3. Confirm the GPS equipment is performing positioning. 4. Verify the connection with the GPS equipment, checking the LED of the corresponding port if connected to the serial LAN interface circuit. 5. If connected to the serial-LAN interface circuit (CMH-2370), ensure its power supply is on. If problems persist, the serial-LAN interface circuit (CMH-2370), internal wiring, or the central control unit (NDC-1590) might be faulty, requiring a repair request from the distributor.

    Why is my JRC Monitor screen not displaying even though the power is on?
    • A
      Anna MaddenAug 26, 2025
      If your JRC Monitor has power but the screen remains blank, first, check the brightness setting and adjust it to an appropriate level. If adjusting the brightness doesn't solve the problem, the internal wiring or the display unit (NWZ-208/ NWZ-207/NWZ-214) may be faulty, and you should request a repair from the distributor.
