EMC Notice
Electromagnetic emissions
The HC271/HC271p monitors are intended for use in the electromagnetic environment specified below. The
customers or the users of the HC271/HC271p monitors should assure that they are used in such an
environment.

RF emissions
CISPR 11
Group 1 The HC271/HC271p 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

Class B The HC271/HC271p is suitable for use in all
establishments, including domestic
establishments and those directly
connected to the public low-voltage power
supply network that supplies buildings
used for domestic purposes.

user of the HC271/HC271p
requires continued operation
during interruptions in the main
power, it is recommended that
the HC271/HC271p be powered
from an uninterruptible power
supply or a battery.
