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 metres (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic survey,
a
should be
less than the compliance level in each frequency
range.
b
Interference may occur in the vicinity of equipment
marked with:
Note 1: At 80MHz and 800MHz 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 cannot be predicted theoretically with
accuracy. To assess the electromagnetic environment in the location due to fixed RF transmitters, an
electromagnetic site survey should be considered. If the measured field strength in the location in which the
device is used exceeds the applicable RF compliance level above, the device should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary, such as
reorienting or relocating the device.
b Over the frequency range 150kHz to 80MHz, field strengths should be less than 3V/m.
4.3.3 Recommended separation distances
This section lists the recommended separation distances between portable and mobile communication
equipment and the device.
The P200T is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled.
The customer or the user of the P200T can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communication equipment (transmitters) and the P200T
as recommended below, according to the maximum output power of the communications equipment.
