Quality of service
The transmitter and the pump are associated as part of an 802.15.4 network for which
the pump functions as the coordinator and the transmitter as an end node. In an adverse
RF environment the pump will assess channel changing needs based on "noise" levels
detected during an energy scan. The pump will perform the energy scan if after 10
minutes no CGM transmitter signal has been received. If the channel change occurs the
pump will send beacons on the new channel.
Transmitter
Sensor
Transmitter temperature: 0 °C to 45 °C (32 °F to 113 °F)
Caution: When operating the transmitter on a tester in air temperatures
greater than 41 °C (106 °F), the temperature of the transmitter may exceed
43 °C (109 °F). This can cause the device to malfunction.
Transmitter relative humidity: 10% to 95% with no condensation
Transmitter pressure: 57.6 kPa to 106 kPa (8.4 psi to 15.4 psi)
Charger temperature: 10 °C to 40 °C (50 °F to 104 °F)
Charger relative humidity: 30% to 75% with no condensation
Transmitter temperature: -20 °C to 55 °C (-4 °F to 131 °F)
Transmitter relative humidity: up to 95% with no condensation
Transmitter pressure: 57.6 kPa to 106 kPa (8.4 psi to 15.4 psi)
Charger temperature: -10 °C to 50 °C (14 °F to 122 °F)
Charger relative humidity: 10% to 95% with no condensation
Transmitter: Seven days of continuous glucose monitoring immediately fol-
lowing a full charge.
Charger: The charger uses one new AAA battery to charge the transmitter.
2.4 GHz, 2M65G1D modulation, less than 1 mW ERP
0.1 mW (-9.9 dBm)
Pump to transmitter frequency: 2.4 GHz; proprietary Medtronic protocol;
range up to 1.8 meters (6 feet)
Utilizes the IEEE 802.15.4 protocol with proprietary data format.
The transmitter expected service life is one year depending on patient us-
age.
