Guidance and manufacturer’s declaration - electromagnetic emissions
The HFA3 is intended for use in the electromagnetic environment specified below. The customer or user of the HFA3 should ensure that it is
used in such an environment.
Emissions Test
Compliance
Electromagnetic environment - guidance
RF emissions
CISPR 11
Group 1
The HFA3 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.
RF emissions
CISPR 11
Class A
The HFA3 is suitable for use in all
establishments other than domestic
establishments and those connected to a low
voltage power supply network which supplies
buildings used for domestic purposes.
Harmonic emissions
