How do I activate my 90-day non-O single entry visa and register my place of stay in Thailand?

A big hello to the learned people administering the site my initial application for 90 day non o single entry on 21st June has come through yesterday now I need to activate it by either overland or flight that's correct ? When I entered on the 12th July without a visa on the exempt I went to immigration the next day to register my place of stay , when I activate the visa do I have to go to immigration in jomtien and register my place of stay again , as on my application I ve already declared it thank you kind regards john
