  If instrument or other system data is missing from some but not all displays on your Raymarine Marine Equipment, check that all required equipment is connected to the network. Verify the status of the Raymarine network switch and ensure that SeaTalkhs/RayNet cables are free from damage. If a software mismatch between equipment is suspected, contact Raymarine technical support.

  foleyfrankSep 6, 2025
  If your Raymarine Marine Equipment display behaves erratically with frequent unexpected resets, system crashes, or other erratic behavior, check the relevant fuses and breakers. Ensure that the power supply cable is sound and that all connections are tight and free from corrosion. Also, verify that the power source provides the correct voltage and sufficient current. You may need to perform a factory reset. For software issues, go to www.raymarine.com and click on support for the latest software downloads.

  Michael PhillipsSep 4, 2025
  If the image on your Raymarine Marine Equipment is too dark or too light, use the brightness controls at the display to adjust accordingly. Adjust the contrast and brightness of the image using the appropriate menu in the thermal camera application. A different Scene Mode setting may be more appropriate for the current conditions; use the SCENE button to adjust.

  Tracy RodriguezAug 25, 2025
  If your Raymarine Monitor shows no depth reading or has lost bottom lock, check the transducer location to ensure it's installed correctly. Also, verify the transducer angle, adjusting if it's too great. If the transducer has a kick-up mechanism, ensure it hasn't kicked up. Check the power supply voltage under load, and inspect the transducer for damage or fouling.

What to do if video is not displayed on Raymarine Marine Equipment?
- N
  ninaperrySep 2, 2025
  If the video is not displayed on your Raymarine Marine Equipment, the camera may be in Standby mode. Use the camera controls (either the thermal camera application or JCU) to wake the camera from standby. Check the thermal camera video cables to ensure they are sound and properly connected, and ensure that the video is connected into video input 1 at the multifunction display or GVM. Also, ensure that the correct video input is selected at the display. Check the power connections to the camera and JCU/PoE injector (if used), and ensure that the power switch/breaker is on and the fuse/breaker is in good condition.

Why isn't the touchscreen working on my Raymarine a75 Marine Equipment?
- M
  Meredith JacksonSep 2, 2025
  If the touchscreen on your Raymarine Marine Equipment does not operate as expected, ensure that the touch lock is disabled. The touch lock can be turned off on the home screen using the Joystick. Also, make sure you are operating the screen with bare fingers, as gloves may prevent correct operation. Calibrate the touchscreen using the setup menus. If there are saltwater deposits on the screen, carefully clean and dry the screen according to the provided instructions.

What causes Raymarine a75 radar to not initialize?
- A
  Andrew ShieldsSep 1, 2025
  If the radar on your Raymarine Marine Equipment will not initialize and the Voltage Control Module (VCM) is stuck in “sleep mode”, check the power connection at the VCM. Ensure the voltage at the input is 12/24V and the voltage at the output is 40V. The issue could be due to an intermittent or poor power connection.

Why is instrument data missing from all Raymarine Marine Equipment displays?
- A
  Anita BartonAug 31, 2025
  If instrument, engine, or other system data is unavailable at all displays on your Raymarine Marine Equipment, check the data bus (e.g., SeaTalkng) wiring and connections to ensure data is being received at the display. Verify the overall integrity of the data bus (e.g., SeaTalkng) wiring. Check the source of the missing data (e.g., ST70 instrument or engine interface) to ensure it is operating. Also, check the power to the SeaTalk bus. If a software mismatch between equipment is suspected, contact Raymarine technical support.

What to do if Raymarine a75 shows no data or scanner message?
- D
  Danielle SullivanAug 30, 2025
  If you have no data or are receiving a 'No scanner' message on your Raymarine Marine Equipment, begin by checking the scanner power supply cable to ensure it is sound and that all connections are tight and free of corrosion. Check the relevant fuses and breakers. Ensure the power source provides the correct voltage and sufficient current, using a voltage booster if needed. Verify that the scanner is correctly connected to a Raymarine network switch or SeaTalkhs crossover coupler, as applicable, and check the status of the Raymarine network switch. Make sure SeaTalkhs/RayNet cables are free from damage and the scanner pedestal switch is in the ON position. If a software mismatch between equipment is suspected, contact Raymarine technical support.
