   Radio frequency interference

   Dear (Name withheld):

   The Federal Communications Commission has received a complaint of harmful
   radio interference that is apparently caused by a  pool pump located at
   (address withheld). This interference has been reported by a licensed
   operator in the Amateur Radio Service. The complainant is:

   (Name withheld)

   (Address withheld)

   (Address withheld)

   Under FCC rules, such equipment as a pool pump is classified as an
   "intentional radiator." This term is used to describe equipment that
   intentionally generates radio-frequency energy and radiates it as part of
   its normal operation. Under these rules, however, it must not cause
   harmful interference. If it does, the operator of the device is
   responsible for correcting the interference, ceasing operation, if
   necessary, whenever such interference occurs.

   To help you better understand your responsibilities under FCC rules, here
   are the most important rules relating to radio and television interference
   from incidental radiators:

          Title 47, CFR Section 15.5 General conditions of operation.

   (b) Operation of an intentional, unintentional, or incidental radiator is
   subject to the conditions that no harmful interference is caused and that
   interference must be accepted that may be caused by the operation of an
   authorized radio station, by another intentional or unintentional
   radiator, by industrial, scientific and medical (ISM) equipment, or by an
   incidental radiator.

   (c) The operator of the radio frequency device shall be required to cease
   operating the device upon notification by a Commission representative that
   the device is causing harmful interference. Operation shall not resume
   until the condition causing the harmful interference has been corrected.

          Title 47, CFR Section 15.15 General technical requirements.

   (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 Sec. 15.105(b)).

   Harmful interference to a licensed radio service from a Part 15 device is
   a violation of FCC Rules. Specifically, the manufacturer is responsible
   for device certification. The device owner however is responsible for
   operating the device in such a manner that it does not cause interference.
   Manufacturers will often bear some of this responsibility as a courtesy to
   their customers. We encourage the parties and manufacturers involved to
   voluntarily resolve this matter without Commission intervention.

   Please be advised that continued operation of the pool pump is not legal
   under FCC rules if it is causing harmful interference. The interference
   must be corrected before its operation may continue. The manufacturer or
   retail seller of the device may be willing to allow you to return the
   device and exchange it for one that will not cause interference.
   Installation of an ac line filter may also help correct this problem. You
   have 30 days from the date of this letter to resolve the interference to
   (name withheld) amateur station and report back to this office. Please
   direct your response to the following address: 1270 Fairfield Road,
   Gettysburg, Pennsylvania 17325.

   If you have any questions about this matter, please contact me at
   717-338-2577. Thank you for your cooperation.
