​The following webinar was recently hosted by Radiometer with Mr Dick Clarke as the presenter. The various elements around TCOM are covered very well. I am not sure how long it will be available for and the first 10 minutes and last 5 minutes relate to the webinar platform and accreditation which is not of any relevance to us.
