7.4 Electromagnetic interferences
The
FRED PA-1
®
is intended for use in the electromagnetic environment specified be-
low. The customer or the user of the
FRED PA-1
®
should assure that it is used in such
an environment.

Group 1
FRED PA-1
®
uses RF energy only for its internal function. There-
fore, its RF emissions are very low and are not likely to cause any
interference in nearby electronic equipment.

is suitable for use in all establishments, including do-
mestic establishments and those directly connected to the public
low-voltage power supply network that supplies buildings used for
domestic purposes.
