ELECTROMAGNETIC COMPATIBILITY (EMC)
Table X-3 Guidance and Manufacturer’s Declaration: Electromagnetic Immunity
The equipment is intended for use in the electromagnetic environment specified in the table below. The customer or
the user of the equipment should ensure that it is used in such an environment.

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

a. Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios,
amateur radios, 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 equipment is used exceeds the applicable RF compliance level above, the
equipment should be observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the equipment.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than [3] V/m.
