Guidance and manufacturer’s declaration - electromagnetic emissions
The RA660 is intended for use in the electromagnetic environment specified
below. The customer or the user of the RA660 should assure that it is used in
such an environment.

RF emissions
CISPR 11
Group 1
The RA660 uses RF energy only for its
internal function.
Therefore, its RF emissions are very low and
are not likely to cause any interference in
nearby electronic equipment.

Recommended separation distances between portable and mobile RF
communications equipment and the RA660.
The RA660 is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the RA660 can help prevent
electromagnetic interferences by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the RA660 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 higher frequency range applies.
Note 2
These guidelines may not apply to all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people.
