Sec.  15.103   Exempted devices.

   The following devices are subject only to the general conditions of
   operation in  Sec.  Sec. 15.5 and 15.29 and are exempt from the specific technical
   standards and other requirements contained in this part. The operator of the
   exempted device shall be required to stop operating the device upon a
   finding by the Commission or its representative that the device is causing
   harmful interference. Operation shall not resume until the condition causing
   the harmful interference has been corrected. Although not mandatory, it is
   strongly recommended that the manufacturer of an exempted device endeavor to
   have the device meet the specific technical standards in this part.

   (a) A digital device utilized exclusively in any transportation vehicle
   including motor vehicles and aircraft.

   (b) A digital device used exclusively as an electronic control or power
   system utilized by a public utility or in an industrial plant. The term
   public utility includes equipment only to the extent that it is in a
   dedicated building or large room owned or leased by the utility and does not
   extend to equipment installed in a subscriber's facility.

   (c) A digital device used exclusively as industrial, commercial, or medical
   test equipment.

   (d) A digital device utilized exclusively in an appliance, e.g., microwave
   oven, dishwasher, clothes dryer, air conditioner (central or window), etc.

   (e) Specialized medical digital devices (generally used at the direction of
   or under the supervision of a licensed health care practitioner) whether
   used in a patient's home or a health care facility. Non-specialized medical
   devices, i.e., devices marketed through retail channels for use by the
   general public, are not exempted. This exemption also does not apply to
   digital devices used for record keeping or any purpose not directly
   connected with medical treatment.

   (f) Digital devices that have a power consumption not exceeding 6 nW.

   (g) Joystick controllers or similar devices, such as a mouse, used with
   digital devices but which contain only non-digital circuitry or a simple
   circuit to convert the signal to the format required (e.g., an integrated
   circuit for analog to digital conversion) are viewed as passive add-on
   devices, not themselves directly subject to the technical standards or the
   equipment authorization requirements.

   (h) Digital devices in which both the highest frequency generated and the
   highest frequency used are less than 1.705 MHz and which do not operate from
   the AC power lines or contain provisions for operation while connected to
   the AC power lines. Digital devices that include, or make provision for the
   use of, battery eliminators, AC adaptors or battery chargers which permit
   operation while charging or that connect to the AC power lines indirectly,
   obtaining their power through another device which is connected to the AC
   power lines, do not fall under this exemption.

   (i) Responsible parties should note that equipment containing more than one
   device is not exempt from the technical standards in this part unless all of
   the devices in the equipment meet the criteria for exemption. If only one of
   the included devices qualifies for exemption, the remainder of the equipment
   must comply with any applicable regulations. If a device performs more than
   one function and all of those functions do not meet the criteria for
   exemption, the device does not qualify for inclusion under the exemptions.
