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 P200DTx is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled.
The customer or the user of the
minimum distance between portable and mobile RF communication equipment (transmitters) and the
as recommended below, according to the maximum output power of the communications equipment.

For transmitter rated at a maximum output power
meters (m) can be estimated using the equation applicable to the frequency of the transmitter, where P is the
maximum output power of the transmitter in watts (W) according to the transmitter manufacturer.
