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 use 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.
Recommended Separation Distances
Recommended Separation Distance Between Portable and Mobile RF Communication Equipment and the ME Equipment
The ME Equipment is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or
the user of the ME Equipment can help prevent electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the ME Equipment as recommended below, according to the maximum output
power of the communication equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters (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 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.
