Portable and mobile RF communications equipment
should be used no closer to any part of the
AffloVest, including the cables, than the
recommended distance calculated from the
equation applicable to the transmit frequency.
Recommended distance:
d = 1.2 m P
d=1.2 m P for 80 MHz to 800 MHz
d=2.3 m P for 800 MHz to 2.5 GHz
Where P is the maximum output power rating of the
transmitter in watts (W) according to the transmitter
manufacturer and d is the recommended distance in
meters (m). The field strength of fixed RF
transmitters, as determined by an electromagnetic
site survey
a
should be less than the compliance
level in each frequency range

Radiated RF
interference as
per IEC 61000-4-3
NOTE 1: The higher frequency range applies at 80 MHz and 800 MHz.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorbtion and reflection
from structures, objects, and persons.
a
The field strength from fixed transmitters, such as base stations for radio telephones and mobile terrestrial radio equipment,
amateur radio stations, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess
the electromagnetic environment in terms of fixed RF transmitters, an electromagnetic site survey should be considered. If the
measured field strength in the location in which the AffloVest is used exceeds the applicable compliance level specified above,
the AffloVest should be observed to verify normal operation. If abnormal performance features are observed, additional
measures may be necessary, such as re-orienting or relocating the AffloVest.
b
The field strength should be less than 3 V/m over the frequency range from 150 kHz to 80 MHz.
The AffloVest is intended for use in the electromagnetic environment specified below. The customer or user of the
AffloVest should ensure that it is used in such an environment.
