RF emissions
CISPR 11
Group 1 The PS27FHDER 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 PS27FHDER 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.
This PS27FHDER complies with appropriate medical EMC standards on emissions to, and interference
from surrounding equipment. Operation is subject to the following two conditions: (1) this device may not
cause harmful interference, and (2) this device must accept any interference received, including interfer-
ence that may cause undesired operation.
Interference can be determined by turning the equipment off and on.
If this equipment does cause harmful interference to, or suffer from harmful interference of, surrounding
equipment, the user is encouraged to try to correct the interference by one or more of the following mea-
sures:
• Reorient or relocate the receiving antenna or equipment.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced technician for help.
Electromagnetic immunity
The PS27FHDER is intended for use in the electromagnetic environment specified below. The customer
or the user of the PS27FHDER should assure that it is used in such an environment.
