Recommended separation distances between RF wireless communications equipment
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.

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 xed RF
transmitter, as determined
by an electromagnetic
site survey, should be less
than the compliance level
in each frequency range.
Interference may occur in
the vicinity of equipment

Note 1: These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reection from structures, objects and people.
WARNINGS!
•This device should not be used in the vicinity or on the top of other electronic equipment such as cell
phone, transceiver or radio control products. If you have to do so, the device should be observed to verify
normal operation.
•The use of accessories and power cord other than those specified, with the exception of cables sold by
the manufacturer of the equipment or system as replacement parts for internal components, may result in
increased emissions or decreased immunity of the equipment or system.
