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%.
Mains power should be that of a typical
commercial or hospital environment.
Mains power should be that of a typical
commercial or hospital environment.
Mains power should be that of a typical
commercial or hospital environment. If the
user of the MAC 5500 requires continued
operation during power mains interruptions,
it is recommended that the MAC 5500 be
powered from an uninterruptible power
supply or a battery.
Power frequency magnetic fields should be
at levels characteristics of a typical location
in a typical commercial or hospital
environment.
