Recommended Separation Distances - Omron HBP-1100 Mode D'emploi

Recommended Separation Distances:
Recommended separation distance between portable and mobile RF
communications equipment and the HBP-1100
The HBP-1100 is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the
HBP-1100 can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications equipment
(transmitters) and the HBP-1100 as recommended below, according to the
maximum output power of the communications equipment.

0,1 0,38
1 1,2
10 3,8
100 12
For transmitters rated at a maximum output power not listed above, the
recommended separation distance d in metres (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.
Note1: At 80MHz and 800MHz, the separation distance for the higher
frequency range applies
Note2: These guidelines may not apply in all situations. Electromagnetic
propagation is affected by absorption and reflection from structures,
objects, and people.
