                      NOTICE OF UNAUTHORIZED OPERATION AND

                    INTERFERENCE TO LICENSED RADIO STATIONS

                              Case # EB-10-SD-0228

   Document Number: W201132940005

   On March 31, 2011, in response to a complaint of interference, agents from
   the San Diego Office, using mobile direction finding techniques,
   determined that radio signals had originated from a radio transmitter
   located in Building 5 at Palm Desert High School in Palm Desert,
   California. The device in question was designed to jam or intentionally
   interfere with licensed radio communications in the cellular and personal
   communications service ("PCS") radio services (47 C.F.R. Parts 22 and 24).
   After the inspection, the operation of the device ceased.

   Persons operating or using radio transmitters must be licensed or
   authorized by the FCC, pursuant to Section 301 of the Communications Act
   of 1934, as amended. In addition, radio transmitting equipment must comply
   with FCC rules. Section 333 of the Act prohibits willful or malicious
   interference with any radio communications of any station licensed or
   authorized by or under the Act or operated by the United States
   Government. In addition, Section 302(b) of the Act, and Section 2.803 of
   the Commission's rules, prohibit the manufacture, importation, marketing,
   sale or operation of devices deliberately designed to jam or disrupt
   wireless communications. The Commission has issued two Public Notices
   specifically stating that the sale and use of transmitters designed to
   prevent, jam or interfere with the operation of cellular and PCS
   telephones is unlawful.

   The operation of the device utilized by you may constitute a violation of
   Sections 333, 302(b), and 301 of the Act, as described above. Such
   operation may subject you to substantial monetary forfeitures, in rem
   arrest action against the offending radio equipment, and criminal
   sanctions including imprisonment. Because unauthorized operation creates a
   danger of interference to important radio communications services, and may
   subject the operator to severe penalties, this warning emphasizes the
   importance of complying strictly with these legal requirements.

   UNAUTHORIZED OPERATION OF THIS RADIO TRANSMITTING DEVICE MUST NOT RESUME.

   You may respond with any information you believe relevant to this warning
   within (10) days from the date of this notice. Your response should be
   sent to the address in the letterhead and reference the listed case
   number. Under the Privacy Act of 1974, we are informing you that the
   Commission's staff will use all relevant material information before it to
   determine what, if any, enforcement action is required to ensure your
   compliance with FCC Rules. This will include any information that you
   disclose in your reply.

   Be advised that this notice does not preclude this office from pursuing
   additional sanctions based upon our investigation of this incident.
