    What to do if my Raymarine Monitor shows no depth reading or lost bottom lock?
    • T
      Taylor DrakeAug 17, 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.

    Why does my Raymarine Monitor not turn on or keep turning off?
    • W
      williamburtonAug 20, 2025
      Your Raymarine Monitor might not be turning on or keeps turning off due to several reasons: a blown fuse or tripped breaker (check and replace if necessary, and inspect for cable damage if fuses repeatedly blow), a poor or damaged power supply cable or connections (ensure the cable is fully inserted and locked, check for damage or corrosion, and flex the cable to check for reboots), incorrect power connection (ensure the installation instructions have been followed), or an insufficient power source (check the power supply voltage under load).

    What to do if my Raymarine Monitor displays a “No Fix” GPS status icon?
    • C
      Carol ConnerAug 23, 2025
      If your Raymarine Monitor displays a 'No Fix' GPS status icon, it could be due to your geographic location or prevailing conditions preventing a satellite fix (check periodically in better conditions or another location), a GPS connection fault (ensure external GPS connections and cabling are correct), or an external GPS antenna in a poor position (ensure the GPS antenna has a clear view of the sky).

    What to do if my Raymarine Monitor will not boot up (re-boot loop)?
    • C
      Christopher ObrienAug 26, 2025
      If your Raymarine Monitor will not boot up, it could be due to the power supply and connection issues. Also, in the unlikely event that the product's software has become corrupted, please try re-flashing the latest software from the Raymarine website. On display products, as a last resort, you can try to perform a ‘Power on Reset’; however, this will delete all settings/presets and user data and revert the unit back to factory defaults.

    What does it mean if my Raymarine Monitor displays 'No Data' or 'No scanner message'?
    • S
      Sean MccoyAug 27, 2025
      If your Raymarine Monitor displays 'No Data' or 'No scanner message', check the scanner power supply cable to ensure it's sound and connections are tight and free from corrosion. Also, check that the scanner is correctly connected to a Raymarine network switch or SeaTalkhs crossover coupler, as applicable. Ensure the scanner pedestal switch is in the ON position.

    How to fix a Raymarine Monitor radar that will not initialize (Voltage control module (VCM) stuck in “sleep mode”)?
    • T
      Timothy Cox MDAug 30, 2025
      If your Raymarine Monitor radar will not initialize because 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.

    Why does my Raymarine Marine GPS System say “No Fix”?
    • J
      Jacob RivasSep 1, 2025
      If the Raymarine Marine GPS System displays a “No Fix” GPS status icon, it could be due to several reasons. First, geographic location or prevailing conditions might be preventing a satellite fix; check periodically to see if a fix is obtained in better conditions or another geographic location. Second, there may be a GPS connection fault; ensure that external GPS connections and cabling are correct and fault free. Third, the external GPS antenna might be in a poor position; ensure it has a clear view of the sky.

    What to do if Raymarine Marine GPS System won't boot up?

      Amy LopezSep 6, 2025
      If your Raymarine Marine GPS System product will not boot up or is in a re-boot loop, first refer to the solutions for 'Product does not turn on or keeps turning off'. If the issue persists, it could be due to software corruption. Try re-flashing the latest software from the Raymarine website. As a last resort, on display products, you can try to perform a ‘Power on Reset’; however, this will delete all settings/presets and user data (such as waypoints and tracks) and revert the unit back to factory defaults.

    How do I fix a Raymarine Marine GPS System with no depth reading?
    • I
      Isaac JonesSep 9, 2025
      If your Raymarine Marine GPS System is showing no depth reading or has lost bottom lock, there are several potential causes. Check that the transducer has been installed in accordance with the instructions provided with it. If the transducer angle is too great, the beam can miss the bottom, so adjust the transducer angle and recheck. If the transducer has a kick-up mechanism, check that it has not kicked up due to hitting an object. With the product under load, use a multi-meter to check the power supply voltage as close to the unit as possible to establish the actual voltage when the current is flowing.

    How do I correct the bearing on my Raymarine Marine GPS System radar?
    • T
      tammy92Sep 12, 2025
      If the bearing of a target on the radar screen of your Raymarine Marine GPS System is incorrect, the radar bearing alignment likely requires correcting. Check and adjust the radar bearing alignment.
