Table 1-2 Guidance and Manufacturer's Declaration - Electromagnetic Immunity - The Centurion
®
Vision
System is intended for use in the electromagnetic environment specied below. The customer or
the user of the Centurion
®
Vision System should assure that it is used in such an environment.
Note: U
T
is the a.c. mains voltage prior to application of the test level.
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 reection from
structures, objects, and people.
a
Field strengths from xed transmitters, such as base stations for radio (cellular/cordless) and land mobile radios, amateur radio, AM and
FM radio broadcast, and TV broadcast cannot be predicted theoretically with accuracy. To access the electromagnetic environment due
to xed RF transmitters, an electromagnetic site survey should be considered. If the measured eld strength in the location in which the
(equipment or system) is used exceeds the applicable RF compliance level above, the (equipment or system) should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating
the Centurion
®
Vision System.
b
Over the frequency range 150 kHz to 80 MHz, eld strengths should be less than 3 V/m.

Electromagnetic Environment-Guidance
Floors should be wood, concrete, or ceramic tile. If oors
are covered with synthetic material, the relative humidity
should be at least 30 %.
Mains power quality should be that of a typical hospital
(including ambulatory surgery center) environment. To avoid
pre- mature shutdown due to fast transients avoid powering
the Centurion
®
Vision System on the same branch circuit
with sources that can generate fast transients (inductive
switching; e.g., high current motors).
Mains power quality should be that of a typical hospital
(including ambulatory surgery center) environment.
Mains power quality should be that of a typical hospital
(including ambulatory surgery center) environment.
If the use of the Centurion
®
Vision System requires
continued operation during power mains interruptions, it
is recommended that the Centurion
®
Vision System be
powered from an uninterruptible power supply or a battery.
Power frequency magnetic elds should be at levels
characteristic of a typical location in a typical hospital
(including ambulatory surgery center) environment.
Portable and mobile RF communications equipment should
be used no closer to any part of the Centurion
®
Vision
System, including cables, than the recommended separation
distance calculated from the equation applicable to the
frequency to the transmitter.
Recommended separation distance:
d = 1.2√P
d = 1.2 √ P 80 MHz to 800 MHz
d = 2.3 √ P 800 MHz to 2.5 GHz
where P is the maximum output power rating to the
transmitter in watts (W) according to the transmitter
manufacturer and d is the recommended separation
distance in meters (m).
Field strength from xed RF transmitters, as determined
by an electromagnetic site survey
a
, should be less than
the compliance level in each frequency range
