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 quality should be that of a typical
commercial or hospital environment.
Mains power quality should be that of a typical
commercial or hospital environment.
Mains power quality should be that of a typical
commercial or hospital environment. If the user
of the handle and charging accessory requires
continued operation during power mains
interruptions, it is recommended that the
handle and charging accessory be powered
from an uninterruptible power supply or a
battery.
; 25/30 cycles
Power frequency magnetic fields should be at
levels characteristic of a typical location in a
typical commercial or hospital environment.
