Guidance and manufacturer's declaration - electromagnetic immunity
The EndoSequence II is intended for use in the electromagnetic environment specified below. The
customer or the user of the EndoSequence II should assure that it is used in such an environment.
NOTE 1 At 80MHz and 800MHz, 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.
a) Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless)
telephones and land mobiles radios, amateur radio, AM and FM radio broadcast and TV broadcast
cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to
fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field
strength in the location in which the EndoSequence II is used exceeds the applicable RF
compliance level above, the EndoSequence II should be observed to verity normal operation. If
abnormal performance is observed, additional measures may be necessary, such as reorienting or
relocating the EndoSequence II.
b) Over the frequency range 150kHz to 80MHz, field strengths should be less than 3 V/m.

Portable and mobile FRO
communications equipment should be
used no closer to any part of the
EndoSequence II, including cables, than
the recommended separation distance
calculated from the equation applicable
to the frequency of the transmitter.
Recommended separation distance
d = 1.2 P
d = 1.2 P 80MHz to 800MHz
d = 2.3 P 800MHz to 2.5GHz
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
transmitters as determined by an
electromagnetic site survey, should be
less than the compliance level in each
frequency range.
