Electromagnetic
environment—guidance
Floors should be wood, concrete,
or ceramic tile. If floors are
covered with synthetic material,
the relative humidity should be
at least 30%.
Line power quality should be
that of a typical commercial or
hospital environment.
Line power quality should be
that of a typical commercial or
hospital environment.
Line power quality should be
that of a typical commercial or
hospital environment. If the user
of the Transcend 365 miniCPAP
requires continued operation
during power line interruptions,
it is recommended that the
Transcend 365 miniCPAP be
powered from the battery.
NOTE: U is the A.C. line
T
voltage before
application of the test
level.
Power frequency magnetic fields
should be at levels characteristic
of a typical commercial or
hospital environment.
Recommended separation
distance: d = 1.17
P
Recommended separation
distance: d = 0.35 80 MHz to

800MHz
Recommended separation
distance: d = 0.70 800MHz to
P
2.5 GHz
where P is the maximum output
power rating of the transmitter
in watts (W) according to the
transmitter manufacturer and
is the recommended separation
distance in meters (m).
Field strengths from fixed RF
transmitters, as determined by
an electromagnetic site survey,
should be less than the
compliance level in each
frequency range.
Interference may occur in the
vicinity of equipment marked
