Table 205: Recommended separation distances (life-supporting devices)
Recommended separation distances between portable and mobile RF communications equipment and the
Accu-Chek Spirit Combo.
The Accu-Chek Spirit Combo is intended for use in the electromagnetic environment in which radiated RF disturbances are controlled.
The customer or the user of the Accu-Chek Spirit Combo can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment (transmitters) and the Accu-Chek Spirit Combo as recom-
mended below, according to the maximum output power of the communication equipment.
Rated maximum output
power of transmitter
(W)
Separation distance according to frequency of transmitter (m)
150 kHz to 80 MHz
d = 1.2 P
80 MHz to 800 MHz
d = 1.2 P
800 MHz to 2.3 GHz
db = 2.3 P
2.3 GHz to 2.5 GHz
da = 11.7 P
0.01 12 cm 12 cm 23 cm 118 cm
0.1 38 cm 38 cm 73 cm 373 cm
1 1.2 m 1.2 m 2.3 m 11.8 m
10 3.8 m 3.8 m 7.3 m 37.3 m
100 12 m 12 m 23 m 118 m
For transmitters rated at a maximum output power not listed above, the recommended separation distance d in metres (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.
