Why is the preheat countdown not showing on my JRC Marine Equipment's radar antenna?
- J
  Joe DavisAug 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.

Why are water depth values not displayed on my JRC Marine Equipment?
- A
  Alexander MasonAug 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.

  Jacob CollinsAug 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.

  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.

What to do if the radar antenna of my JRC Marine Equipment won't rotate?
- M
  Matthew PachecoAug 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 is the log not displayed correctly on my JRC Marine Equipment?
- J
  Jason WilsonAug 27, 2025
  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.

What to do if the radar antenna of my JRC Marine Equipment is not getting power?
- M
  Mark MullenAug 27, 2025
  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 Gyro compass azimuth not displayed correctly on my JRC Marine Equipment?
- S
  Sandra RobinsonAug 27, 2025
  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.
