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

recommended that the Curve system be
powered from an uninterruptible power sup-

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:
