Do I need to report my Non O Retirement visa every 90 days if I leave Thailand?

Hi

I have a Non O Retirement visa and a multiple entry permit.I understand I need to report every 90 days.

Do I need to report every 90 days even when I have been out of Thailand for a while? Is it strictly 90 days from issuance, or when you have been 90 days in the Kingdom.

I understand the reporting, T47, can be done online.

Thanks
