to minimize any RF interference. If your
transmitter is still not communicating with
your pump, call the 24 Hour HelpLine or
your local representative for assistance.
There is RF interference
from other devices.
Storing the devices
Store the transmitter, charger, and tester in a clean, dry location at room
temperature. If the transmitter is not in use, you must charge the transmitter at least
once every 60 days. Although not required, you may store the transmitter on the
charger. If you are storing the transmitter on the charger, you must disconnect and
reconnect the charger and the transmitter at least once every 60 days.

Guardian Link wireless communication
Quality of service
The Guardian Link transmitter and the MiniMed 640G insulin 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.
The Guardian Link transmitter will initiate a channel search when beacon detection fails
on the associated channel. The search will be conducted across all five channels. When
the beacon is located the transmitter will rejoin on the identified channel. Upon reassociation any missed packets (up to 10 hours) will be transmitted from the transmitter
to the pump.
In normal operation the transmitter will transmit a packet every 5 minutes and retransmit
the packet if the data is corrupted or missed.
Radio frequency (RF) communications specifications
• Pump to transmitter frequency: 2.4 GHz; proprietary Medtronic protocol; range up to
6 feet (1.8 meters).
• Utilizes the IEEE 802.15.4 protocol with the proprietary data format.
Data security
The MiniMed 640G insulin pump is designed to only accept radio frequency (RF)
communications from recognized and linked devices (you must program your pump to
accept information from a specific device).
The MiniMed 640G insulin pump and system components (meters and transmitters)
ensure data security via proprietary means and ensures data integrity using error
checking processes, such as cyclic redundancy checks.

strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones
and land mobile radios, amateur radio, AM and FM radio broadcasts and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the
location in which the Guardian Link is used exceeds the applicable RF compliance level above, the
Guardian Link should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the Guardian Link.
