NOTE: If necessary to achieve the IMMUNITY TEST LEVEL, the distance between the transmitting antenna and the IE
EQUIPMENT or ME SYSTEM may be reduced to 1m. The 1, 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 signa.
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.
