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.

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.

as determined by an electromagnetic site
survey, should be less than the compliance
