  Jenna LopezNov 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...

Why is my JRC Monitor screen not displaying even though the power is on?

  Mr. Jesse FitzpatrickAug 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.
