What to do if the radar antenna of my JRC Marine Equipment won't rotate?
- J
  Joel ShafferAug 27, 2025
  If the radar antenna of your JRC Marine Equipment does not rotate even when the [TX/ST-BY] button is pressed, check these potential causes: * Verify the connection with the radar antenna. * Ensure the safety switch of the radar antenna is set to ON. * Check the power supply wiring from the power supply unit (NBD-945) inside the processing unit to the interface circuit (CMH-2452) to ensure power is being supplied to the radar antenna.

Why are rudder angles not displayed correctly on my JRC Marine Equipment?
- M
  Melissa ButlerAug 28, 2025
  If rudder angles 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 rudder angle indicator might not be on; turn it on. * The connection with the rudder angle indicator could be abnormal; verify the connection and, if a rudder angle indicator is connected to the terminal board circuit (CQD-2322), 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 or the processing unit (NDC-1678), requiring repair from the distributor.

  Patrick JacksonAug 29, 2025
  If wind direction/wind speed data 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 power supply for the anemoscope/anemometer might not be on; turn it on. * The connection with the anemoscope/anemometer could be abnormal; verify the connection and, if an anemoscope/anemometer is connected to the terminal board circuit (CQD-2322), 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 or the processing unit (NDC-1678), requiring repair from the distributor.

  Traci LopezAug 29, 2025
  If water depth values 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 echo sounder might not be on; turn it on. * The connection with the echo sounder could be abnormal; verify the connection and, if an echo sounder is connected to the terminal board circuit (CQD-2322), 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 or the processing unit (NDC-1678), requiring repair from the distributor.

- G
  gailberryAug 30, 2025
  If the preheat count down of the radar antenna is not displayed on your JRC Marine Equipment, check the following: * Verify the connection with the radar antenna. * Ensure the safety switch of the radar antenna is set to ON. * If a solid-state radar antenna is connected, note that preheat count-down is not displayed for this type of antenna. If the issue persists, the radar antenna, 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 Marine Equipment has no power?
- M
  Melanie LyonsSep 1, 2025
  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.

Why is the screen not displayed on my JRC Marine Equipment monitor, even though it's powered on?
- C
  chadhunterSep 2, 2025
  If, although power is supplied to the monitor of your JRC Marine Equipment, the screen is not displayed, it may be because the brightness of the monitor is set to the minimum level. Adjust the brightness of the monitor to the appropriate level. If the issue persists, the internal wiring or the display (NWZ-208/NWZ-214) may be faulty, requiring repair from the distributor.

Why is no radar image displayed on my JRC Marine Equipment?
- F
  Frederick FosterAug 26, 2025
  If no radar image is displayed on your JRC Marine Equipment, check the following: * Verify the connection with the radar antenna. * Ensure the GAIN value is set to a proper level, not the minimum. * Make sure the SEA/RAIN value is set appropriately, not the maximum. Additionally, if using a radar antenna with a magnetron, the magnetron may be significantly deteriorated and require replacement. If these steps do not resolve the issue, the radar antenna, internal wiring, power supply (NDB-945) inside the processing unit, or the processing unit (NDC-1678) itself may be faulty, requiring repair from the distributor.
