Radio frequency immunity aspects
The CA-200F device is intended for use in the electromagnetic environment specified below. The
customer or the user of the CA-200F device should assure that it is used in the said environment.

RF communications equipment should not
be used in the vicinity of the device,
including its cables,
unless the recommended
separation distance
calculated from the
equation applicable to the frequency of the
transmitter is observed.
Recommended separation distance
d = 1.2 P from 150kHz to 80MHz
d = 1.2 P from 80 MHz to 800 MHz
d = 2.3 P from 800 MHz to 2.5 GHz
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 ).

The fixed RF transmitter field strength, as determined by an electromagnetic site survey,
may be lower than the compliance level in relation to each frequency range.
Interference may occur in the vicinity of equipment marked with the following symbol:
Recommended separation distances between portable and mobile RF communications equipment and
the surgical Navigation device
The CA-200F device is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of device can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications equipment (transmitters) and the device 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 separation distance for the higher frequency range applies
(2) These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection
from structures, objects and people.
