Chapter 1 Safety
Recommended separation distances between portable and mobile RF
communications equipment and MySono U6
This product is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of this product can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and this product 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]
150kHz to 80MHz
80MHz to 800MHz
800MHz to 2.5GHz
V1=0.01Vrms E1=3 V/m E1=3V/m
0.01 35.00 0.11 0.23
0.1 110.68 0.36 0.73
1 350.00 1.16 2.33
10 1106.80 3.68 7.37
100 3500.00 11.66 23.33
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 80MHz and 800MHz, the separation distance for 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.
