§ 95.1209   Permissible communications.

   (a) Except for the purposes of testing and for demonstrations to health care
   professionals, MedRadio programmer/control transmitters may transmit only
   non-voice  data  containing  operational,  diagnostic  and therapeutic
   information associated with a medical implant device or medical body-worn
   device that has been implanted or placed on the person by or under the
   direction of a duly authorized health care professional.

   (b)  Except as provided in § 95.627(b) no MedRadio implant or body-worn
   transmitter shall transmit except in response to a transmission from a
   MedRadio  programmer/control transmitter or in response to a non-radio
   frequency actuation signal generated by a device external to the body with
   respect to which the MedRadio implant or body-worn transmitter is used.

   (c) MedRadio programmer/control transmitters may be interconnected with
   other telecommunications systems including the public switched telephone
   network.

   (d) For the purpose of facilitating MedRadio system operation during a
   MedRadio  communications  session,  as  defined  in  § 95.627, MedRadio
   transmitters in the 401-406 MHz band may transmit in accordance with the
   provisions  of  § 95.627(a)  for  no  more  than  5 seconds without the
   communications of data; MedRadio transmitters may transmit in accordance
   with the provisions of § 95.627(b)(2) and (b)(3) for no more than 3.6 seconds
   in  total within a one hour time period; and MedRadio transmitters may
   transmit in accordance with the provisions of § 95.627(b)(4) for no more than
   360 milliseconds in total within a one hour time period.

   (e)  MedRadio programmer/control transmitters may not be used to relay
   information in the 401-406 MHz band to a receiver that is not included with
   a medical implant or medical body-worn device. Wireless retransmission of
   information intended to be transmitted by a MedRadio programmer/control
   transmitter  or information received from a medical implant or medical
   body-worn transmitter shall be performed using other radio services that
   operate in spectrum outside of the 401-406 MHz band.

   (f)  MedRadio  programmer/control  transmitters  and  medical  implant
   transmitters  may not be used to relay information in the 413-419 MHz,
   426-432 MHz, 438-444 MHz, and 451-457 MHz bands to a receiver that is not
   part of the same Medical Micropower Network. Wireless retransmission of
   information to a receiver that is not part of the same Medical Micropower
   Network  must  be performed using other radio services that operate in
   spectrum outside of the 413-419 MHz, 426-432 MHz, 438-444 MHz, and 451-457
   MHz  bands.  Not  withstanding  the  above  restrictions,  a  MedRadio
   programmer/control transmitter of an MMN may communicate with the MedRadio
   programmer/control transmitter of another MMN to coordinate transmissions so
   as to avoid interference between the two MMNs.

   (g)  Medical  body-worn transmitters may relay only information in the
   2360-2400 MHz band to a MedRadio programmer/control transmitter or another
   medical body-worn transmitter device that is part of the same Medical Body
   Area Network (MBAN). A MedRadio programmer/control transmitter may not be
   used  to relay information in the 2360-2400 MHz band to other MedRadio
   programmer/controller transmitters. Wireless retransmission of all other
   information from an MBAN transmitter to a receiver that is not part of the
   same MBAN shall be performed using other radio services that operate in
   spectrum  outside of the 2360-2400 MHz band. Notwithstanding the above
   restriction, a MedRadio programmer/control transmitter in the 2360-2400 MHz
   band may communicate with another MedRadio programmer/control transmitter in
   the  2360-2400  MHz  band  to  coordinate transmissions so as to avoid
   interference between the two Medical Body Area Networks.

   (h) MedRadio programmer/control transmitters operating in the 413-419 MHz,
   426-432 MHz, 438-444 MHz, and 451-457 MHz bands shall not transmit with a
   duty cycle greater than 3 percent.
