Mains power quality
should be that of a typi-
cal commercial or hos-
pital environment. If the
user of the upper arm
stlye requires continued
operation during power
mains interruptions, it is
recommended that the
Prolife PS1 Standard
be powered from an
uninterruptible power
supply or a battery

Portable and mobile RF communica-
tions equipment should be used no
closer to any part of the Prolife PS1
Standard, including cables, than the
recommended separation distance
calculated from the equation applica-
ble to the frequency of the transmitter.
Recommend separation distance:
3 V
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 pow-
er rating of the transmitter in watts
(W) according to the transmitter man-
ufacturer and d is the recommended
separation distance in meters (m).
Field strengths from fixed RF trans-
mitters as determined by an elec-
tromagnetic 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
