Recommended separation distances between
portable and mobile RF communications equipment and the MicroCO
The MicroCO is intended for use in an e lectromagnetic environment in which
radiated R F disturbance s are controlled. The customer or the user of the
MicroC O can help prevent electromagnetic interference by maintaining a
m inimum distance betwe en portable and mobile RF communications equipment
(transmitters) and the MicroCO as re commended below, according to the
m ax imum output powe r of the communications equipment.

For transmitters rated at a maximum output powe r not listed above, the
re com mended separation distance d in m eters (m) can be e stimated using the
e quation applicable to the fre quency of the transmitter, whe re P is the
m ax imum output powe r rating of the transmitter in watts (W) according to the
transmitter m anufacturer.
NO TE 1 At 80 MHz and 800 MHz, the sep aration distance for the higher
fre quency range applies.
NO TE 2 The se guidelines may not apply in all situations. Electromagnetic
propagation is affected by absorption and re flection from structures obje cts and
