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

(W)
150 KHz to 80 MHz
For transmitters rated at a maximum output power not listed above, the recommended separation
distance d in metres (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.

NOTE If necessary to achieve the IMMUNITY TEST LEVEL, the distance between the transmitting
antenna and the ME EQUIPMENT or ME SYSTEM may be reduced to 1 m. The 1 m test distance is
permitted by IEC 61000-4-3.
a ) For some services, only the uplink frequencies are included.
b ) The carrier shall be modulated using a 50% duty cycle square wave signal.
c ) As an alternative to FM modulation. 50% pulse modulation at 18 Hz may be used because while it
does not represent actual modulation, it would be worst case.
The MANUFACTURER should consider reducing the minimum separation distance, based on RISK
MANAGEMENT, and using higher IMMUNITY TEST LEVELS that are appropriate for the reduced
minimum separation distance. Minimum separation distances for higher IMMUNITY TEST LEVELS
shall be
calculated using the following equation:
Where P is the maximum power in W, d is the minimum separation distance in m, and E is the
IMMUNITY
TEST LEVEL in V/m.
