Electromagnetic environment-guidance
RF signal of Fingertip Pulse Oximeter is simply
created by its internal function. Therefore, its
RF interference is very low and is not likely to
cause any interference to nearby electronic
equipment.
The Fingertip Pulse Oximeter applies to all
establishments, including domestic
establishments and those directly connected
to the public low-voltage power supply
network that supplies buildings used for
domestic purposes.
