Guidelines And Manufacturer's Declaration - Electromagnetic Emissions; Recommended Safety Distances Between Portable And Mobile Hf Telecommunication Devices And The Nebufirst Inhaler - Fahl NEBUFIRST Gebrauchsanweisung

12.0 INSTRUCTIONS WITH REGARD TO EMC
EN
● Medical electrical devices are subject to special precautions with regard to EMC and must be installed in accordance with the
EMC instructions specified below.
● Portable and mobile HF communication equipment can influence medical electrical devices.
● The use of accessories, transducers or cables other than those specified can lead to increased emission or a reduced elec-
tromagnetic immunity of the device or system.

For transmitters of which the maximum nominal power is not indicated in the table above, the recommended safety distance
d in metres (m) can be determined using the equation that belongs to the respective column, P being the maximum nominal
power of the transmitter in watt (W) as specified by the manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not be applicable in all cases. The propagation of electromagnetic values is influenced by ab-
sorptions and reflections of buildings, objects and people.
INHALER is intended for operation in an environment such as the one specified below. The customer or user

Electromagnetic environment - guideline
The NEBUFIRST INHALER uses HF energy exclusively for its
®
internal function. Therefore, its HF emission is very low and it is
unlikely that neighbouring electronic equipment will be disrup-
ted.
The NEBUFIRST INHALER is suitable for use in all facilities,
®
including facilities in living quarters and facilities which are
directly connected to a public power supply that also supplies
buildings used for residential purposes.
