Compliance level: Compliance to the tested levels
Electromagnetic environment - guidance:
Portable RF communications equipment (including peripherals such as antenna cables and external
antennas) should be used no closer than 30 cm (12 inches) to any part of the System, including cables
specified by Abbott Diabetes Care. Otherwise, degradation of the performance of the System could
result.
The table below lists the immunity levels at specific test frequencies for testing the e!ects of some
wireless communications equipment. The frequencies and services listed in the table are representative
examples in various locations where the System may be used.
a) For some services, only the uplink frequencies are included.
b) The carrier shall be modulated using a 50 % duty cycle square wave signal.
c) As an alternative to FM modulation, 50 % pulse modulation at 18 Hz may be used because while it does not represent actual modulation, it
would be worst case.
Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey,
less than the compliance level in each frequency range.
Interference may occur in the vicinity of equipment marked with the following symbol:
a Field strengths from fixed 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 fixed RF
transmitters, an electromagnetic site survey should be considered. If the measured field strength in the
location in which the System is used exceeds the applicable RF compliance level above, the System
should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating the System.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 10 V/m.
