The device is intended for use in the electromagnetic environment specified below. The customer or the 

user of the device, should assure that it is used in such an environment.

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:

                                                                E=

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.
