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.

385 1.8 0.3 27 27 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 transmitter 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
frequency range. Interference may occur in
the vicinity of equipment marked with the
following symbol:

Note 1: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection
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.
