Guidance And Manufacturer's Declaration - Electromagnetic Emissions
The Model G137 is intended for use in the electromagnetic environment specified below. The customer or the user
of the Model G137 should assure that it is used in such an environment.
IEC 60601
Immunity test
Test level
Radiated RF 3 V/m
IEC 61000-4-3 26 MHz to 2.5 GHz
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 mobile 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 Model G137 is used
exceeds the applicable RF compliance level above, the Model G137 should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating the Model G137.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Compliance

Portable and mobile RF communications equipment
3 V/m
should be used no closer to any part of the Model G135,
including cables, than the Recommended separation
distance calculated from the equation applicable to the
frequency of the transmitter.
d = 1.7 P 80 MHz to 800 MHz
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 recommended separation
distance in meters (m).
