If your Raymarine Radar scanner won't connect, several factors could be at play. First, check the data cable (if applicable) to ensure it's securely connected at both ends and in good condition. For Wi-Fi connections, verify that you've entered the correct Wi-Fi passcode, which can be found on the scanner packaging or the serial number label. Also, the Raymarine Radar unit might shut down after 30 minutes without a Wi-Fi connection to an MFD; you can awaken it via the 'Power Up Radar' option on your MFD. Make sure the power supply thermal breaker hasn't tripped or the fuse hasn't blown; reset or replace them once if necessary. Confirm the power supply maintains the correct voltage. Ensure all system products have the latest software. If using a SeaTalkhs or RayNet network switch, check tha...
