Introduction

Indications for use

The Medtronic CareLink™ USB is indicated for use by patients at home and clinicians in a medical office setting to facilitate communication between Medtronic diabetes therapy
management devices that use Paradigm-compatible RF telemetry (MWT1)* and a personal computer that uses data management application software.

Contraindications

None known.

Warnings

Product may pose a choking hazard for young children.

Compliance information

This device complies with the United States Federal Communications Commission (FCC) and international standards for electromagnetic compatibility. The 868.35 MHz version
(MMT-7305WW) conforms to the essential requirements of the Council Directive 1999/5/EC (R&TTE).

The following information is provided in accordance with Federal Communications Commission (FCC) regulations.
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device

must accept any interference received, including interference that may cause undesirable operation.
This device 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 wireless devices

Common consumer electronic devices that transmit in the same frequency band used by the MMT-7305 CareLink USB may prevent the CareLink USB from receiving the data
sent by Medtronic diabetes therapy management devices. Most cellular 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 CareLink USB.

Communication problems can typically be resolved by ensuring that the distance between transmitter and receiving device is less than 1.9 meters (6 feet), and by turning off or
moving away from other RF transmitting devices. You can also reorient or relocate the CareLink USB and/or the transmitting 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 2.3 meters (7.5 feet) from the transmitter or receiving
device while the phone is being used (greater separation distance may be required for certain devices).

RF Compatibility

Medtronic diabetes therapy management devices transmit in different radio frequency (RF) bands, depending on the region of the world in which they are sold. If you purchased
your Medtronic diabetes therapy management device and CareLink USB in different regions, they may not work together. If your CareLink USB does not seem to recognize your
device, this may be the reason. Contact your local HelpLine for assistance.

* MWT1 is the brand name for the Medtronic MiniMed proprietary RF telemetry protocol.

Installing the CareLink USB on your computer

Your CareLink USB must be properly installed before it can transfer data from Medtronic diabetes therapy management devices. Please follow these installation instructions.
Do not plug your CareLink USB into your computer until you have installed the associated drivers and/or are prompted by the CareLink software.

Installing the CareLink USB drivers:

• Refer to the user guide of your Medtronic Diabetes data management application software for instructions on how to load the CareLink USB drivers onto your computer.

• After you have followed the user guide instructions, plug your CareLink USB into your computer.

The illustrations at right show the CareLink USB being plugged into the USB port on the back of a personal
computer. You may also plug your CareLink USB into USB ports on the front of your personal computer, or into
any USB port on a laptop computer.

It is recommended that the CareLink USB be plugged directly into a USB port on the computer. A USB extension
cable can be used if you do not have easy access to your computer’s USB ports, but it is recommended that you
use only a USB cable with a protected female end (see illustration at right).

Troubleshooting

• If you plug your CareLink USB into a USB port on your computer and it does not work, remove it and plug it into another USB port on your computer. This is a rare but
continuing issue with USB ports and many USB devices. If your CareLink USB does not work in any USB port on your computer, call your local HelpLine for assistance.

• Electrostatic discharge (ESD) may temporarily prevent the CareLink USB from transmitting. If you touch the metal of the CareLink USB or the unprotected end of a USB
cable while it is connected to your computer, and your CareLink USB stops transmitting, remove it and plug it back in, being careful not to touch the metal parts.
