Note 1: At 80 MHz and 800 MHz, the higher frequency range applies.
Note 2: These specifications may not be applicable in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and persons.
(a): The electromagnetic field strengths of fixed radiofrequency emitters, such as base stations for
mobile telephones (cellular/cordless), mobile radios, amateur radios, AM/FM radio broadcasts and
TV broadcasts cannot be determined exactly by theory. To assess the electromagnetic
environment due to fixed radiofrequency emitters, an electromagnetic environment
measurement must be made. If the measured radiofrequency field strength in the immediate
environment where the product is used exceeds the compliance level specified above, the
performance of the product must be tested to verify whether it conforms to the specifications. If
abnormal performance is observed, additional measures may be necessary, such as reorienting or
relocating the product.
(b): In the 150 kHz to 80 MHz frequency range, the electromagnetic field strengths must be less than
3 V/m.
10. 4 RECOMMENDED SEPARATION DISTANCES
The P5 N
XS is intended for use in an electromagnetic environment in which radiated
EWTRON
radiofrequency disturbances are controlled.
The P5 N
XS user and/or installer can help prevent electromagnetic interference by maintaining
EWTRON
a minimum distance between portable and mobile radiofrequency communications equipment
(emitters) and the P5 N
recommended in the table below.

For emitters rated at max. power not listed above, the recommended separation distance d in meters (m) can be estimated
using the equation applicable to the frequency of the emitter, where P is the max. power rating of the emitter in watts (W)
