Note: At 80 MHz and 800 MHz, the highest frequency range is applied
Note: These guidelines may not be applicable in all situations. Electromagnetic propagation is influ-
enced by the absorbance and deflection of structures, objects and people.
a. The intensity of the fixed transmitter's field such as radiophone (cellular/cordless) bases and land
mobiles, amateur radios, FM and AM radio and television, theoretically cannot be determined precise-
ly. To evaluate the electromagnetic environment due to fixed RF transmitters, a local electromagnetic
investigation should be considered. If the measured field intensity in which the R07A will be used, is
above the applicable conformity level of RF described above, the R07A should be under observation
to verify normal function. In case of anomalous function additional attention may be required, such as
changing position or orientation of the R07A.
b. Above the frequency range from 150 kHz to 80 MHz, the intensity of the field must be below 3 V / m.
Recommended distance between communication portable and mobile and R07A
R07A is for use in an electromagnetic environment in which irradiated RF interferences are con-
trolled. The clients or users can minimize electromagnetic interference by maintaining a minimal
distance between portable and mobile RF transmitters and R07A as indicated below, based on the
max output power of the communication devices.

For those transmitters with a max nominal output power not mentioned above , the advised distance
in meters (m) can be estimated using the equation applicable to the frequency of the transmitter,
where P is the max output power in watt (W) according to the transmitter's builder.
Note 1: at 80 MHz and 800 MHz, the distance applied refers to the highest range frequency
Note 2: These guidelines may not be applicable in all situations. Electromagnetic propagation is influ-
enced by the absorbance and deflection of structures, objects and people.
