Guidance and manufacturer’s declaration - Electromagnetic Immunity
The
Brivo OEC 715/785/865
Mobile C-Arm X-Ray Product is intended to
use in the specified
electromagnetic environment. The purchaser or user of the Brivo OEC 715/785/865 Mobile C-Arm X-Ray
Product should assure that it is used in an electromagnetic environment as described below:

Portable and mobile RF communications
equipment are used no closer to any part of
the
Brivo OEC 715/785/865 Mobile C-Arm X-
Ray Product, including cables, than the
recommended separation distance calculated
from the equation appropriate for the
frequency of the transmitter.

The formulas are applicable for Ed3.0 only.
Note: P is the 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 transmitters, as
determined by an electromagnetic site survey
a
, are less than the compliance level in each
frequency range
b
.
Interference may occur in the vicinity of
equipment marked with the following symbol:
a: Field strengths from fixed transmitters, such as base stations for cellular telephones and land mobile radios, amateur
radio, AM and FM radio broadcast, and TV broadcast cannot be estimated accurately. To assess the electromagnetic
environment due to fixed RF transmitters, an electromagnetic site survey should be performed. If the measured field
strength exceeds the RF compliance level above, observe the Brivo OEC 715/785/865 Mobile C-Arm X-Ray Product to
verify normal operation in each use location. If abnormal performance is observed, additional measures may be
necessary, such as re-orienting or relocating the [EQUIPMENT and/or SYSTEM].
b: Over the frequency range 150 kHz to 80 MHz, field strengths are less than 3 V/m.
NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
Note3: These are guidelines. Actual conditions may vary.
