It looks as though there have been several attempts to enter the wrong Security Code (or wrong sequence ) ..If you have the correct Security Code ( Make sure by checking on here ... Quote your Serial Number beginning with M . ) then I suggest that you disconnect the radio (or battery ) leave off for 10 minutes, reconnect radio (or battery) , then switch radio on and leave. Check the display~If it hasn`t re-set then leave for a period of time ...ie ...until the radio has unlocked automatically , which then allows the Security Code to be re-entered. Beware: It might have to be left for many hours (up to !2 ?) without interruption depending on how many previous faulty attempts...If that doesn`t work then I`m afraid that you`ll have to take it into a Radio Specialist ..Good Luck !
