Recommended separation distance between portable and mobile RF communications equipment and the EUT
There is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The user
of the EUT can help prevent electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the EUT as recommended below, according to the maximum
output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters
(m) can be estimated using 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.
NOTE
•
At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
•
These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection
from structures, objects and people.

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 EUT is used exceeds the applicable
RF compliance level above, the EUT should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as re-orienting or relocating the EUT.

Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [V1] V/m.
