In an adverse RF environment the pump will assess channelchanging needs based on "noise" levels detected during an energy scan. The pumpwill perform the energy scan if after 10 minutes no CGM transmitter signal has beenreceived. If the channel change occurs the pump will send beacons on the newchannel.The transmitter will initiate a channel search when beacon detection fails on theassociated channel. The search will be conducted across all five channels. When thebeacon is located the transmitter will rejoin on the identified channel. Upon re-association any missed packets (up to 10 hours) will be transmitted from thetransmitter to the pump.In normal operation the transmitter will transmit a packet every 5 minutes andretransmit the packet if the data is corrupted or missed.Data securityThe MiniMed 640G insulin pump is designed to only accept radio frequency (RF)communications from recognized and linked devices (you must program your pumpto accept information from a specific device).-17- EnglishMP6025977-021 / 1RELEASED
