Communication problems can usually be resolved by:
• ensuring that there is less than 1.8 meters (6 feet) 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 31 cm (12 inches) 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 31 cm (12 inches) away from the receiving device, transmitter or glucose
meter when a glucose measurement is being transmitted.
