EasyOne Pro™ / EasyOne Pro™ LAB 157
Appendix
a) Field strengths from fixed transmitters, such as base stations for radio (cellular/cord-
less) telephones and land mobile radio, AM and FM radio broadcast and TV broadcast
cannot be predicted theoretically with accuracy. To assess the electromagnetic envi-
ronment due to fixed RF transmitters, an electromagnetic site survey should be con-
sidered. If the measured field strength in the location in which EasyOne Pro™ is used
exceeds the applicable RF compliance level above, EasyOne Pro™ should be
observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating EasyOne Pro™.
b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/
m.
Recommended separation distances between portable and mobile
RF communication equipment and EasyOne Pro™
EasyOne Pro™ is intended for use in the electromagnetic environment on which radi-
ated RF disturbances are controlled. The customer or the user of EasyOne Pro™ can
help prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and EasyOne Pro™
as recommended below, according to the maximum output power of the communica-
tions equipment

mum output

For transmitters rated at a maximum output power not listed above, the recommended
separation distance d in meters (m) can be estimated using the equation applicable to
the frequency of the transmitter, where P is the maximum output power rating of the
transmitter in watts (W) according to the transmitter manufacturer.
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.
