Interpreting the 2012 requirement explicitly -- then yes, I agree.
But, 2015 added some practical common sense to the requirement in (B). A reputable manufacturer would likely provide service personnel who had completed "a documented training program acceptable to the health care facility...contracted to work with specific equipment as installed in that facility."
5.1.14.2.2.5 Qualifications.
(A) Persons maintaining these systems shall be qualified to perform these operations.
(B) Appropriate qualification shall be demonstrated by any of the following:
(1) A documented training program acceptable to the health care facility by which such persons are employed or contracted to work with specific equipment as installed in that facility
I encourage my facilities to use due diligence when hiring service personnel, because being a 6030 or 6040 may meet the minimum requirements of the code, but that doesn't necessarily qualify someone to service specific equipment.
