To Next PageTo Next PageWhy is the radar image azimuth incorrect on my JRC JMR-5400 Marine Equipment?
If the azimuth of the radar image is not displayed correctly on your JRC Marine Equipment, it may be because the azimuth is not set correctly. Set the azimuth correctly. Alternatively, CCRP may not be set correctly; set CCRP correctly. Also, the GPS radar antenna position may not be set correctly; set it correctly.
Why is the radar image range incorrect on my JRC JMR-5400?
If the range of the radar image is not displayed correctly on your JRC Marine Equipment, it may be because the range is not set correctly. Set the range correctly. Alternatively, CCRP may not be set correctly; set CCRP correctly. Also, the GPS radar antenna position may not be set correctly; set it correctly.
Why can't radar images be tuned on my JRC Marine Equipment?
If radar images cannot be tuned on your JRC Marine Equipment, it may be because the magnetron is deteriorated significantly (if using a radar antenna that uses a magnetron). Replace the magnetron. Alternatively, coarse tuning adjustment may not have been performed correctly; perform it correctly. If a solid-state radar antenna is connected, note that a tuning bar is not displayed for this type of antenna.
Why is no radar image displayed on my JRC JMR-5400?
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.
Why is the screen not displayed on my JRC JMR-5400 Marine Equipment monitor, even though it's powered on?
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.
What to do if the monitor of my JRC JMR-5400 has no power?
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.
What should I do if my JRC Marine Equipment displays 'Marine VHF radio does not respond'?
If the following popup window is displayed on your JRC Marine Equipment: "Marine VHF radio does not respond. Check the connection with the equipment," it indicates that the power supply for the VHF or HUB is not turned on, or there is a problem with the connection of a VHF LAN cable. Check the power supply of the VHF or HUB and the connection of the LAN cable.
What does it mean when my JRC JMR-5400 Marine Equipment displays 'System has detected an error'?
If the following popup window is displayed on your JRC Marine Equipment: "System has detected an error. Turn the power off and on again," it indicates that a communication error has occurred. Close the popup window, and after confirming it is safe to do so, turn the power off and then on again.
Why is the preheat countdown not showing on my JRC JMR-5400's radar antenna?
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 JMR-5400 Marine Equipment?
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.
