Table 4：
RECOMMENDED SEPARATION DISTANCES BETWEEN PORTABLE AND MOBILE RF
COMMUNICATION AND THIS SYSTEM
This system is intended for use in an electromagnetic environment in which radiated RF
disturbance are controlled. The customer or the user of This system can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communication equipment (transmitters) and This system as recommended below, according to
the maximum output power of the communication equipment.
Rated Maximum

150kHz -80MHz
P5.3d =
80MHz -800MHz
P2.1d =
800MHz -2.5GHz
P3.2d =
0.01 0.35 0.12 0.23
0.1 1.11 0.37 0.74
1 3.50 1.17 2.34
10 11.07 3.69 7.38
100 35.00 11.67 23.34
For transmitters at a maximum output power not listed above, the recommended separation
distanced in meters (m) can be determined 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.
If image distortion occurs, it may be necessary to position this system further from sources of
conducted RF noise or to install external power source filter to minimize RF noise to an acceptable
level.
Note:
1. At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
2. These guidelines may not apply in all situations. Electromagnetic propagation is affected
by absorption and reflection from structures, objects and people.
