Where P is the maximum output

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.
Interference may occur in the
vicinity of equipment marked with
the following symbol:
Field strengths from fixed RF 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 device is used exceeds
the applicable RF compliance level above, device should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary,
such as re-orienting or relocating device.
Over the frequency range 0.15 MHz to 80 MHz, field strengths should be less than 3 V/m.
Table 4
Recommended separation distances between
portable and mobile RF communications equipment and device
Device is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of device can help prevent
electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and device, as recommended below,
according to the maximum output power of the communications equipment.
