                    CERTIFIED MAIL-RETURN RECEIPT REQUESTED

   December 22, 2014

   Mr. Naren Gursahaney

   President & CEO

   The ADT Corporation

   1501 Yamato Road

   Boca Raton, FL 33431

   Re: EB-FIELDNER-14-00017944

   Dear Mr. Gursahaney:

   The Federal Communications Commission has received complaints that an ADT
   alarm system may be causing harmful radio interference to an operator in
   the Amateur Radio Service. The ADT customer in this case is:

   (Name withheld)

   (Address withheld)

   Scottsdale, AZ 85260

   The licensed radio Amateur is:

   (Name withheld)

   (Address withheld)
   Scottsdale, AZ 85260

   Tel: (Number withheld)

   (Name withheld) reports he is experiencing high levels of radio noise from
   the ADT system. Based on this report, the noise is strong enough that the
   Commission could consider it to be harmful interference. The Commission
   has the responsibility to require operators of systems that cause such
   interference to rectify these problems within a reasonable time.

   Under FCC rules, most electronic devices and equipment are classified as
   an "unintentional radiators." This term is used to describe equipment that
   intentionally generates radio-frequency energy but does not intentionally
   radiate it. Another common device classification is the "incidental
   radiator." This type of equipment does not intentionally generate any
   radio-frequency energy, but may create such energy as an incidental part
   of its intended operation. In either case, under FCC rules, such equipment
   must not be operated in such a way that it causes harmful interference to
   a licensed radio service.

   To help you better understand these responsibilities under FCC rules, here
   are the most important rules relating to radio and television interference
   from unintentional and 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 15.13 Incidental radiators.

   Manufacturers of these devices shall employ good engineering practices to
   minimize the risk of harmful interference.

   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)).

   So far, the complainant has attempted unsuccessfully to resolve this
   problem and as a result the matter has been referred to our office. We
   would appreciate anything you can do to help resolve this problem. I would
   also encourage you or someone from ADT to contact (name withheld) directly
   using the information previously provided.

   If you have any questions about this matter or the FCC rules, please
   contact me in writing at 1270 Fairfield Road, Gettysburg, PA 17325. Thank
   you in advance for your help and cooperation.

   Sincerely,

   Laura L. Smith, Esq.
