a
The field strengths of fixed transmitters e.g. base stations of mobile telephones and mobile radio devices, amateur
radio, AM and FM radio broadcasting, and TV broadcasting cannot be accurately predicted. To assess the electromagnetic
environment with respect to fixed RF transmitters, an electromagnetic survey of the site should be considered. If the
measured field strength in the location in which the enPulsPro is used exceeds the applicable RF compliance level, the
enPulsPro should be observed in order to verify normal operation. If abnormal output is observed, additional measures may
be necessary (e.g. reorienting or relocating the enPulsPro).
b
In the frequency range of 150 kHz to 80 MHz, the field strengths should be less than 3 V/m.
Recommended separation distances between portable and mobile RF communications equipment and the
enPulsPro
The enPulsPro is intended for use in one of the electromagnetic environments specified below. The customer or the user of
the enPulsPro can help prevent electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the enPulsPro – depending on the output power of the
communications equipment as specified below.

For transmitters for which the maximum nominal output is not specified in the above table, the recommended separation distance d in
meters (m) can be determined using the equation given for the corresponding column, where P is the maximum rated power of the
transmitter in watts (W) in accordance with the manufacturer of the transmitter.
NOTE 1: At 80 and 800 MHz, the higher frequency range applies.
NOTE 2: These guidelines may not apply in all cases. The spread of electromagnetic variables is affected by the absorption and reflection
of structures, objects, and people.
