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.

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.
