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

Separation Distance According to Frequency of Transmitter
(meters)
150 kHz to 80 MHz
d = 1.2 P
80 MHz to 800 MHz
d = 0.35 P
800 MHz to 2.5 GHz
d = 0.7 P
0.01 0.12 0.04 0.07
0.1 0.38 0.11 0.22
1 1.2 0.35 0.7
10 3.8 1.11 2.21
100 12 3.5 7
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 of the transmitter 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 aected by absorption and
reection from structures, objects and people.
