Guidance and manufacturer’s declaration – electromagnetic immunity
Where P is the maximum output power rating of the transmitter in watts (W) according to the transmitter manufacturer and d is the
recommended separation distance in meters (m).
Field strengths from xed RF transmitters. as determined by an electromagnetic site survey,
a)
should be less than the compliance
level in each frequency range.
b)
Interference may occur in the vicinity of equipment marked with the following symbol:
Note At 80 MHz and 800 MHz, the higher frequency range applies.
Note These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reection from
structures, objects and people.
a ) Field strengths from xed transmitters, such as base stations for radio (cellular / cordless) telephones and land mobile radios, amateur radio, AM and FM radio
broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to xed RF transmitters, an
electromagnetic site survey should be considered. If the measured eld strength in the location in which the Accu-Chek Spirit Combo insulin pump is used
exceeds the applicable RF compliance level above, the Accu-Chek Spirit Combo insulin pump or the device, which contains it should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the device containing the Accu-Chek
Spirit Combo insulin pump.
b ) Over the frequency range 150 kHz to 80 MHz, eld strengths should be less than 10 V / m.
c ) Possible shorter distances outside ISM bands are not considered to have a better applicability of this table.
d
) Exclusion band for Bluetooth
®
ISM 2.4 GHz communication channel
e ) Compliance band for the system equipment
