Portable and mobile RF communications equipment should be
used no closer to any part of the device, including cables, than the
recommended separation distance calculated from the equation
applicable to the frequency of the transmitter.
Recommended separation distance:
d = 1.2
150 kHz to 80 MHz
d = 1.2
80 MHz to 800 MHz
d = 2.3
800 MHz to 2.5 GHz
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 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 b.
Interference may occur in the vicinity of equipment marked with the
following symbol:
NOTE 1: At 80 MHz and 800 MHz, 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 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 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 re-orienting or relocating the device.
b: Over the frequency range 150 kHz to 80 MHz, the field strengths should be less than 3 V/m.
Recommended Separation Distances between Portable and Mobile RF Communications Equipment and This Device: The device is
intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user
of this device can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and this device 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 1: At 80 MHz and 800 MHz, the separation distance for 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.
