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.
