I am thinking through a support arrangement where the machine specialist and the local operator do not share a fluent language. Would you agree a written description of each proposed diagnostic step before the call, or ask someone to translate as it happens? My concern is keeping an explanation separate from permission to act, especially with a remote connection involved.
I'd use a read-back in the operator's own words, with the authorised local person confirming before any action. A translated sentence isn't proof everybody understood the same thing.
