Dear George,
Look in 47 CFR 15.103 Exempted Devices. You are refering to section (b)
exempted from the technical requirements of part 15 are "digital devices
used exclusively as an electronic control or power system utilized by a
public utility or in an industrial plant..."

equipment is classified as a "radio frequency device" or "digital device" and
not selling to the US goverment you must comply with the technical requirements
of part 15, or part 18. Part 18 section 121 allows for exemptions for certain
ultrasound and MRI equipment. Other than that, I'm certain you have to comply!

Dear Compliance Collegues
CFR47 sets emission limits for digital devices. As far as I know
there is or there was an exemption for machine controls, i.e. there
are no emission limits for industrial machines ( I am not referring to
ISM as defined by 47CFR18)
I can not find this exemption in the 1993 edition of the CFR 47.
Can anybody point me the ºº of CFR where this exemptions or
was mentioned ?
Thanks in advance
George
