Electromagnetic environment - Guidance
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.
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.

Electromagnetic environment
— Guidance
Floors should be wood,
concrete or ceramic tile. If
floors are covered with
synthetic material, the relative
humidity should be at least
30%.
The main power quality should
be that of a typical commercial
or hospital environment.
The main power quality should

The main power quality should
be that of a typical commercial
or hospital environment. If the
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.
