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. Ther
efore, its RF emissions are very
low and are not likely to cause any
interference in nearby electronic equipment.
