RF GUIDANCE
Recommended separation distances between portable and mobile RF communications
equipment at the TMB-1014.
The TMB-1014 is intended for use in an electromagnetic environment in which
radiated RFdisturbances are controlled. The customer or the user of the TMB-1014
can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmittters) and the
TMB-1014 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.
NOTE 1 At 80MHz and 800MHz, the separation distance for the higher frequency
range applies.
NOTE 4 These guidelines may not apply in all situations. Electromagnetic propagation
is affected by absorption and reflection from structures, objects, and people.
