§ 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 only relay information in the
   2360-2400 MHz band to a MedRadio programmer/control transmitter 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 another MedRadio programmer/controller
   transmitter. Wireless retransmission of information 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.

   (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.
