Electromagnetic Compliance
Manufacturer's declaration of electromagnetic immunity
Immunity test IEC 60601
Portable and mobile RF communications equipment should
be used no closer to any part of the OML LINQ™, including
cables, than the recommended separation distance calculated
from the equation applicable to the frequency of the transmitter.
Conducted RF
IEC 61000-4-6
Radiated RF
IEC 61000-4-3
Note 1: Where (P) is the maximum output rating of the transmitter in watts (W) according to the
transmitter manufacturer and (d) is the recommended separation distance in metres (m).
Note 2: Field strengths from fixed RF transmitters, as determined by an electromagnetic site survey,
should be less than the compliance level in each frequency range
vicinity of equipment marked with the following symbol.
Note 3: At 80 MHz and 800 MHz, higher frequency range applies.
Note 4: These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
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
which the OML LINQ™ is used, exceeds the applicable RF compliance level above, the OML LINQ™
should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orientating or relocating the OML LINQ™.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
