User guide

These standards are designed to provide reasonable protection against excessive radio frequency
interference and prevent undesirable operation of the device from unwanted electromagnetic interference.
Operation is subject to the following two conditions:
1 This device has been tested and found to comply with the regulations governing such devices in your
area. For the specific regulation and test results for your area, please contact your local representative.
2 This device generates, uses, and can radiate radio frequency energy and, if installed and used in
accordance with the instruction, may cause harmful interference to radio communications. If the device
does cause interference to radio or television reception, you are encouraged to try to correct the
interference by one or more of the following measures:
• Reorient or relocate the insulin pump/remote control/transmitter/meter
• Increase the separation between the insulin pump/remote control/transmitter/meter and the
device that is receiving/emitting interference
The meter and the transmitter send information to the pump using radio frequency. If other devices that
use radio frequency are in use, such as cell phones, cordless phones and wireless networks, they may
prevent communication between the pump and the meter. This interference will not cause any incorrect
data to be sent and will not cause any harm to your pump or meter. Moving away from or turning off
these other devices may allow communication. Refer to the Troubleshooting, alerts and alarms chapter
to correct interference problems you may have.
Wireless transmission between the pump and transmitter within the 1.8 meters (6 feet) operating range
may be interrupted due to the transmitter orientation and the pump position on the body. Move the
pump closer to the transmitter or to another position. If a Lost Sensor alarm has occurred retry:
Main > Sensor > Link to Sensor > Find Lost Sensor
If you have questions, please contact your local Medtronic Diabetes representative.
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 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 transmitter.
The pump includes a programmable WEAK SIGNAL alert that notifies you when one or more expected
transmissions were not received as expected by the pump. (The pump will also issue a LOST SENSOR alert if
communication is interrupted for an extended period of time.)
