Gendex GXS-700 TM
Guidance and Manufacturer's Declaration - Electromagnetic Immunity
The GXS-700 sensor, used with a compliant computer, is intended for use in the electromagnetic
environment specified below. The customer or the user of the GXS-700 sensor should assure that it is
used in such an environment.
Immunity test IEC 60601
test level
3 Vrms
Conducted RF
150 kHz to 80
IEC 61000-4-6
Radiated RF 3 V/m
IEC 61000-4-3 80 MHz to 2,5
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.

Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mo-
bile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with ac-
curacy. 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 GXS-700 sensor is used exceeds
the applicable RF compliance level above, the GXS-700 sensor should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the
GXS-700 sensor.

Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m

Electromagnetic environment - guidance
Portable and mobile RF communications equip-
ment should be used no closer to any part of the
GXS-700 sensor, including cables, than the rec-
ommended separation distance calculated from
the equation applicable to the frequency of the
transmitter.
Recommended separation distance
=
d 1 2 , P
80 MHz to 800 MHz
=
d 1 2 , P
=
d 2 3 , P 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 recom-
mended 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
b
frequency range.
Interference may occur in the vicinity of equip-
ment marked with the following symbol:
