Mains power quality should
be that of atypical commer-
cial or hospital environment.
If the user of this device
requires continued operation
during power mains inter-
ruptions, it is recommended
that the device be powered
from an uninterruptible
power supply or a battery.

Portable and mobile RF communi-
cations equipment should be used
no closer to any part of this device,
including cables, than there com-
mended separation distance calcu-
lated from the equation applicable
to the frequency of the transmitter.
Recommended separation
distance
d = 1.2√ P 150 kHz to 80 MHz
d = 1.2√ P 150 kHz to 80 MHz
d = 2.3√ P 80 MHz to 2.5G MHz
Where P is the maximum output po-
wer rating of the transmitter in watts
(W) according to the transmitter ma-
nufacturer and d is the recommended
separation distance in meters (m).b
Field strengths from fixed RF
transmitters, as determined by
an electromagnetic site survey c,
should be less than the compliance
level in each frequency ranged.
Interference may occur in the
vicinity of equipment marked
