§ 15.21   Information to user.

   The users manual or instruction manual for an intentional or
   unintentional radiator shall caution the user that changes or
   modifications not expressly approved by the party responsible for
   compliance could void the user's authority to operate the equipment. In
   cases where the manual is provided only in a form other than paper,
   such as on a computer disk or over the Internet, the information
   required by this section may be included in the manual in that
   alternative form, provided the user can reasonably be expected to have
   the capability to access information in that form.
