Table 18 Guidance and Manufacturer's Statement – Recommend Separation
Recommended separation distances between portable and mobile RF communications
equipment and the Model AR-9800
The Model AR-9800 Synergy
RF
System is intended for use in an electromagnetic environment in
which radiated RF disturbances are controlled. The customer or the user of the Model AR-9800
can help prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the Model AR-9800 as
recommended below, according to the maximum output power of the communications
equipment.
Rated maximum output
power of transmitter [W]
Separation distance according to frequency of transmitter [m]
150 kHz to 80 MHz
d = 1.2 √P
80 MHz to 800 MHz
d = 1.2 √P
150 kHz to 80 MHz
d = 1.2 √P
0.01 0.12 0.12 0.23
0.1 0.38 0.38 0.73
1 1.2 1.2 2.3
10 3.8 3.8 7.3
100 12 12 23
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 separation distance for 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.
