Medtronic MiniLink Manuel D'utilisation page 4

The MiniLink does not interfere with any radio frequency signals
transmitted from outside sources. These FCC standards are designed
to provide reasonable protection against excessive radio frequency
interference and prevent undesirable operation of the device from
unwanted electromagnetic interference.
Important: Changes or modifications not expressly approved
by the party responsible for compliance could void the user's
authority to operate the equipment.
RF Interference from other devices
Common consumer electronic devices that transmit in the same
frequency band used by the MMT-7703 MiniLink transmitter may
®
prevent the receiving device (Guardian REAL-Time monitor or
®
MiniMed Paradigm REAL-Time insulin pump) from receiving the
glucose information sent by the transmitter. Most cellular (mobile)
phones and 900 MHz cordless phones, when transmitting or
receiving, may cause significant interruption of transmitter-receiver
communication. It is likely that other devices operating in similar
frequency ranges will have a similar effect. This interference, however,
will not cause any incorrect data to be sent and will not cause any
harm to your MiniLink.
Guardian REAL-Time monitors and MiniMed Paradigm REAL-Time
insulin pumps include a programmable "Weak Sensor" alert that
notifies you when one or more expected MiniLink transmissions were
not received as expected by the receiving device. (The receiving
device will also issue a "Lost Sensor" alert if communication is
interrupted for approximately 40 minutes.)
Communication problems can typically be resolved by ensuring that
the distance between transmitter and receiving device is less than 6
feet (1.8 meters), and by turning off or moving away from other RF
transmitting devices. You can also reorient or relocate the MiniLink
and/or the receiving device to try to correct the interference. Testing
conducted with several different cellular phones suggests that
interference will not be a problem if the phone is at least 12 inches (31
cm) from the transmitter or receiving device while it is being used
