GUIDANCE AND MANUFACTURER’S DECLARATION – ELECTROMAGNETIC IMMUNITY
AccuRelief™ electrical stimulators are intended for use in the electromagnetic environment specified below.
The customer or the user of these electrical stimulators should assure that it is used in such environment.
Immunity test IEC 60601 test level Compliance level Electromagnetic environment - guidance
Conducted RF
lEC 61000-4-6
Radiated RF
lEC 61000-4-3
Not applicable
3 V/m
80 MHz to 2.5 GHz
3 V/m
Portable and mobile RF
Communications equipment should be used no closer to any part
of the device, including cables, than the recommended separation
distance calculated from the equation applicable to the frequency
of the transmitter.
Recommended separation distance
d = 1.2 √P
d = 1.2 √P 80 MHz to 800 MHz
d = 2.3 √P 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 separation distance in meters (m).
Field strengths from fixed RF transmitters, as determined by an
electromagnetic site survey,
a
should be less than the compliance
level in each frequency range.
b
Interference may occur in the vicinity of
equipment marked with the following symbol:
