Electromagnetic environ‐
ment - guidelines
Floors should be made of
wood or concrete or have
ceramic tiles. When the
floor is made of synthetic
material, the relative humi‐
dity must be at least 30%.
The quality of the supply
voltage should correspond
to that of a typical business
or hospital environment.
The quality of the supply
voltage should correspond
to that of a typical business
or hospital environment.
The quality of the supply
voltage should correspond
to that of a typical business
or hospital environment.
When the user of the KEY
Laser 1243 needs conti‐
nued operation even when
the power supply is inter‐
rupted, it is recommended
to supply the KEY Laser
1243 from an uninterrup‐
ted power supply or a bat‐
tery.
Magnetic fields at the
mains frequency should
correspond to typical valu‐
es in a business and hos‐
pital environment.
