Electromagnetic environment - directives
NOTE 1 At 80 MHz and at 800 MHz, the highest range of frequencies is applicable.
NOTE 2 These directives may not be applicable to all situations. Electromagnetic propagation is affected by absorption
and reflections from structures, objects and persons.
ᵃ The strength of the fixed emitter fields such as radiotelephone base stations (cellular/cordless), mobile terrestrial radios,
amateur radios, AM and FM radio transmitters and TV transmitters cannot be calculated theoretically with any degree of
accuracy. To assess the electromagnetic environment due to fixed RF emitters, an on-site electromagnetic survey must
be carried out. If the strength of the field measured at the location in which the PRD-7140100A is used exceeds the
applicable RF compliance level set out above, the PRD-7140100A must be monitored to check that it is operating
normally. If the PRD-7140100A is observed to be performing abnormally, additional measures may be needed such as re-
orientating or repositioning it.
ᵇ The field strength over the 150 kHz to 80 MHz range must be lower than 3 V/m.
Recommended separation distances between portable and mobile RF communication devices and the PRD-
7140100A
The PRD-7140100A is designed to be used in electromagnetic environments in which radiated RF emissions are
controlled. PRD-7140100A customers and users can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communication devices (emitters) and the PRD-7140100A, as
recommended below and in accordance with the maximum emitted power of the communication devices in question.

In the case of a transmitter whose assigned maximum output power is not indicated above, the recommended separation
distance d in metres (m) can be estimated using the applicable equation for the transmitter frequency, where P is the
maximum characteristic power output of the transmitter in Watts (W) according to its manufacturer.
NOTE 1 At 80 MHz and at 800 MHz, the separation distance for the highest range of frequencies is applicable.
NOTE 2 These directives may not be applicable to all situations. Electromagnetic propagation is affected by absorption
and reflections from structures, objects and persons.
