@Lloyd *******
yes, I did. But I explained my situation of temporary living away from Korat for a few months due to family reasons and they let me keep my TM30 for Korat to switch back to ( I wasn't sure at the time if that was the correct procedure). I'll go along and see what they say with the old TM30, when I return to Korat next week. Thank you very much for putting my mind at rest.
