Table 205: Recommended separation distances (life-supporting devices)
Recommended separation distances between portable and mobile RF communications equipment and the Accu-Chek
Insight insulin pump.
The Accu-Chek Insight insulin pump is intended for use in the electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the Accu-Chek Insight insulin pump can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the Accu-Chek
Insight insulin pump as recommended below, according to the maximum output power of the communication equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meter (m) can be estimated using the equation
applicable to the frequency of the transmitter, where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer.
