Electromagnetic Compliance
OML Remote
Manufacturer’s declaration of electromagnetic immunity continued
Portable and mobile RF communications equipment should be used
no closer to any part of the OML Remote, including cables, than the
recommended separation distance calculated from the equation applicable
to the frequency of the transmitter.

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,
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 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 Remote is used, exceeds
the applicable RF compliance level above, the OML Remote 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 Remote.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
