The KOWA FM-600 uses RF energy only for its internal function. Therefore,
its RF emissions are very low and are not likely to cause any interference in
nearby electronic equipment.
The KOWA FM-600 is suitable for use in all establishments other than domes-
tic and those directly connected to the public low-voltage power supply net-
work that supplies buildings used for domestic purposes.

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 commer-
cial or hospital environment.

If the user of the KOWA FM-600 requires continued op-
eration during power mains interruptions, it is recom-
mended that the KOWA FM-600 be powered from an
uninterruptible power supply or a battery.
Power frequency magnetic fields should be at levels
characteristic of a typical location in a typical commer-
cial or hospital environment.
