Portable and mobile RF communications
equipment should be used no closer to any
part of the EMMA gas analyzer including
cables than the recommended separation
distance calculated from 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 and d is the
recommended separation distance in meters
(m).
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 1: At 80 MHz and 800 MHz, the higher frequency range applies.
Note 2: 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 the
location in which the EMMA gas analyzer is used exceeds the applicable RF compliance level above,
the EMMA gas analyzer should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating the EMMA gas
