Guidance and Manufacturer's Declaration: Electromagnetic Immunity
Model 240-030-970 is intended for use in the electromagnetic environment specified below.
The customer or the user of Model 240-030-970 should ensure that it is used in such an
IEC 60601 Test

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 240-030-970 system is used exceeds the applicable
RF compliance level above, the Model 240-030-970 system should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as
reorienting or relocating the Model 240-030-970 unit.
(b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Portable and mobile RF communications
equipment should be used no closer
to any part of the Wireless Transmitter
system, including its cables, than the
recommended separation distance
calculated from the equation applicable to
the frequency of the transmitter.
