radar not fonctionning correctly

[Chuck - Raymarine - Moderator]

Welcome to the Raymarine Forum Martin,

It is recommended that you verify that the Tune Adjust setting (MENU->RADAR SET-UP->TUNE ADJUST->TUNE ADJUST) has been configured to AUTO. If so, and the problem persists, then there would unfortunately appear to be failure within the radome necessitating that it be serviced or replaced. If purchased within the last 30 days, it may be returned to the dealer. If purchased more than 30 days ago, it should be sent to Raymarine’s Product Repair Center to be bench checked / serviced.
