Recommended separation distances between portable and mobile
RF communications equipment and the Model MH-DR103
The model JC-114N (MH-DR103) is intended for use in the electromagnetic environment in which radiated Rf disturbances are controlled. The
customer or the user of the model JC-114N (MH-DR103) can help prevent electromagnetic inference by maintaining a minimum distance between
portable and mobile Rf communications equipment (transmitters) and the model JC-114N (MH-DR103) 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 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 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.
