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 Guardian REAL-Time monitor 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 Guardian REAL-Time monitor includes a programmable WEAK SIGNAL alert that notifies you when one
or more expected transmissions were not received as expected by the receiving device. (The receiving
device will also issue a LOST SENSOR alert if communication is interrupted.)
Communication problems can usually be resolved by:
• ensuring that there is less than 6 feet (1.8 meters) between the receiving device and transmitter, to
include RF glucose meters;
• turning off or moving away from other RF transmitting devices; or
• reorienting or relocating the transmitter or receiving device, or both.
Communications problems may also occur due to cellular telephone interference. Testing conducted with
several different cellular telephones indicates that, while a glucose value is being transmitted, using a cell
phone within 12 inches (31 cm) of receiving devices, transmitters or RF glucose meters can interfere with
reception of the transmitted values. In the event of such interference, normal communication can be re-
established by:
• turning the cell phone off; or
• keeping the cell phone at least 12 inches away from the receiving device, transmitter or glucose meter
when a glucose measurement is being transmitted.
