Recommended separation distances between portable and mobile RF communications
equipment and the SE-1200 Pro&SE-1201 Pro ECG
The SE-1200 Pro&SE-1201 Pro ECG is intended for use in an electromagnetic environment in
which radiated RF disturbances are controlled. The customer or the user of the SE-1200
Pro&SE-1201 Pro ECG can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment (transmitters) and the
SE-1200 Pro&SE-1201 Pro ECG 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 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 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected
by absorption and reflection from structures, objects, and people.
