Electromagnetic Environment - Guidance
Floors should be wood, concrete or ceramic
tile. If floors are covered with synthetic mate-
rial, the relative humidity should be at least
30%.
Mains power quality should be that of a typi-
cal commercial or hospital environment.
Mains power quality should be that of a typi-
cal commercial or hospital environment.
Power frequency magnetic fields should be
at levels characteristic of a typical location in
a typical commercial or hospital environment.
Mains power quality should be that of a typi-
cal commercial or hospital environment. If the
Curve system user requires continued opera-
tion during power mains interruptions, it is
recommended that the Curve system be
powered from an uninterruptible power sup-
ply or a battery.
Electromagnetic Environment - Guidance
Portable and mobile RF communications equip-
ment should be used no closer to any part of the
Curve system, including cables, than the rec-
ommended separation distance calculated from
the equation applicable to the frequency of the
transmitter.
Recommended separation distance:
d = 1.17√P
d = 1.17√P
80 MHz to 800 MHz
d = 2.3√P
800 MHz to 2.5 GHz
