§  15.15   General technical requirements.

   (a) An intentional or unintentional radiator shall be constructed in
   accordance with good engineering design and manufacturing practice.
   Emanations from the device shall be suppressed as much as practicable,
   but in no case shall the emanations exceed the levels specified in
   these rules.

   (b) Except as follows, an intentional or unintentional radiator must be
   constructed such that the adjustments of any control that is readily
   accessible by or intended to be accessible to the user will not cause
   operation of the device in violation of the regulations. Access BPL
   equipment shall comply with the applicable standards at the control
   adjustment that is employed. The measurement report used in support of
   an application for Certification and the user instructions for Access
   BPL equipment shall clearly specify the user-or installer-control
   settings that are required for conformance with these regulations.

   (c) Parties responsible for equipment compliance should note that the
   limits specified in this part will not prevent harmful interference
   under all circumstances. Since the operators of part 15 devices are
   required to cease operation should harmful interference occur to
   authorized users of the radio frequency spectrum, the parties
   responsible for equipment compliance are encouraged to employ the
   minimum field strength necessary for communications, to provide greater
   attenuation of unwanted emissions than required by these regulations,
   and to advise the user as to how to resolve harmful interference
   problems (for example, see § 15.105(b)).
