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 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.

Recommended Separation Distance
This device can be used under the environment that radiated RF disturbances are controlled. The user should maintain a
minimum distance between portable and mobile RF communications equipment to prevent electromagnetic interference.
Following recommended distance is calculated 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 can
be estimated using the equation applicable to the frequency of transmitter, where “p” is the maximum output power rating of
the transmitter in watts according to the transmitter manufacturer.
Note1: at 80M-800MHz, the separation distance for the higher frequency range applies.
Note2: these guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and refection
from structures, objects and people.
