Recommended separation distance
�� = 0,6 ∗ √��
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 and electro-magnetic 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:

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
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.
