Why can't radar images be superimposed on my JRC Marine Equipment?
- T
  Tracy GonzalesSep 5, 2025
  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.

Why is no radar image displayed on my JRC Marine Equipment?
- L
  Lori DicksonAug 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.

What to do if my JRC Marine Equipment does not recognize the radar antenna?
- M
  Matthew RitterSep 2, 2025
  If the radar antenna is not acknowledged by your JRC Marine Equipment, there are several potential causes: * The connection with the radar antenna is abnormal; check the connection. * Power is not supplied from the power supply unit to the radar antenna; check the power supply wiring of the interface circuit (CMH-2452) from the power supply unit and the power supply connection inside the radar antenna. If these steps don't resolve the issue, the radar antenna, internal wiring, or the processing unit (NDC-1678) 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?
- D
  Debbie KingSep 1, 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.
