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 be absorption and reflection from structures, objects and people.
a Field strengths from fixed transmitters, such as base stations for ratio (cellular/cordless)
telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV
broadcast cannot be predicated 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 E-connect S is used exceeds the applicable RF compliance level
above, the E-connect S should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as reorienting of
relocating the E-connect S.
b Over the frequency range 150 kHz to 80MHz, field strengths should be less than 3 V/m.
Recommended separation distances between portable and mobile RF communications
equipment and the E-connect S.
The E-connect S is intended for use in an electromagnetic environment in which radiated
RF disturbances are controlled. The customer or the user of the E-connect S can help
prevent electromagnetic interference by maintaining a minimum distance between portable
and mobile RF communications equipment (transmitters) and the E-connect S as
recommended below, according to the maximum output power of the communications
equipment.
