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.

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
80 MHz to 800 MHz
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,
a
should be less than the compliance level in each
frequency range.
b
Interference may occur in the vicinity of equip-
ment marked with the following symbol:
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.
a
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.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m
