B-3
The device is intended for use in an electromagnetic environment in
which radiated RF disturbances are controlled. The customer or the
user of the device can help prevent electromagnetic interference by
maintaining a minimum distance between RF wireless
communications equipment and the device as recommended below,
according to the maximum output power of the communications
equipment.

RF wireless
communications equipment
should be used no closer to
any part of the device,
including cables, than the
recommended separation
distance calculated from the
equation applicable to the
frequency of the transmitter.
Recommended separation
distance
Where P is the maximum
output power rating of the
ransmitter in watts (W)
according to the transmitter
manufacturer and d is the
recommended separation
distance in meters (m).
Field strengths from fixed
RF transmitter, as
determined by an
electromagnetic site survey,
should be less than the
compliance level in each
